PI E2E Outbound

PI E2E Outbound is a test that will search for the message in SAP PI/PO middleware platform based on conditions specified in the Variables of Automation Object. It can trigger message by itself via output control or check the outbound message triggered by other test case or manual action.

Top of the screen with Automation Object (AO) ID, description and test type.

Basic Information

Parameter name

Description

Example

Interface

SAP PI/PO interface name.

In SAP PO, the best information to see interface service name is an ICO definition.

SI_O_PurchaseOrder - SAP PO interface name

Namespace

Namespace from ICO.

The name and namespace will allow to automatically build test cases just based on providing message GUID/number from middleware. Based on content, the interface name/namespace will be checked, and automatically configuration object proposed.

Test Case Creation

Parameter name	Description	Example
PI: Ignore parent message during TC creation	This flag is used for scenarios with multiple receivers. If you create a test case based on the message that is part of the bigger scenario, then engine will search for the initial message that SAP PI/PO received. This requires at least logging the BI processing step (as SAP does not recommend staging). If you would like to create the test case for a single receiver or the BI logging is not available, then you need to check this checkbox
Message version after processing	A version of the message to be fetched from the SAP PI/PO persistence. Here we specify the version which contains after mapping version of the message - already processed by SAP PI/PO. If empty, Global Parameter is used.	Depending on the SAP PI version can be either: numeric: -1 caption: AM
Child Test Case Automation Object	Automation Object(s) used to link and create child test cases. This parameter allows for automatic creation of linked outbound test cases during save. Following Automation Object types can be used as child: 5 PI E2E Outbound 7 IDoc Outbound 13 SAP CPI E2E Outbound

ABAP Stack SAP PI Integration

Parameter name	Description	Example
PI: Landscape where interface exists on the ABAP stack	Name of the PI ABAP Landscape. It is required to access the ABAP stack PI messages.
PI: ABAP stack: Read output message from Java persistence	This flag needs to be checked in the case when the ABAP stack PI sends a message to the JAVA adapter

Test Case Execution

Parameter name	Description	Example
Trigger the output from message control (NAST)	How to trigger Output Control within Outbound test cases?
Flat File Line Separator	The character used for end-of-line determination in Flat File messages: for example, CLRF - Unix. The parameter is used to display the comparison report better and display the reference and new message line by line. "Carriage Return and New line" character should be stored as CRLF "Line Feed" should be stored as LF (Unix based files) There is no default value, so the parameter is obligatory for CSV files Use \|\| to enter multiple alternative separators e.g. CLRF\|\|'	CLRF
Line Separator Escape Character	Escape character for line separator. Used to avoid line breaks in case separator is used in the file content. Value of this parameter should be aligned with specific format used by tested interface. Example: If line separator is set to ' and escape character is ? following split is applied: Source: NAD+SU+8720121000874::3++Test?'file'NAD+SU+8236459000874 Split: NAD+SU+8720121000874::3++Test?'file' NAD+SU+8236459000874
Flat Files Compare with payload validations applied	If this checkbox is checked, Payload Validation rules are applied before files comparison and the match content is replaced by the placeholders. This can in some cases result in better flat file comparison results, especially in case of many missing lines.

Test Case Validation

Parameter name	Description	Example
Validate message output	This flag allows activating output payload validation for SAP PI/PO The validation is performed before the final backend validation, and the results are combined. It is the same validation as used by default by PI Unit Test type.
Ignore Receiver Validation	By default receiver name and party are compared with reference message as part of the test. This flag disables receiver validation.
PI: Validate message status	SAP PI/PO message processing status will be taken as a part of the test case result. By default, the processing status is not part of the test as such, for example, the communication channel may be deactivated not to send test messages. This option is helpful when performing validation of receiver communication channels. It would not validate the results of processing in the channel but at least collect SAP PO status.
PI: Validate message attachments	This flag allow to check SAP PI/PO message attachments as a part of the test.
Show XML in the original order (unsorted)	This flag determines if the lines of the file in the XML Comparison Report should be displayed in the original order or should be sorted alphabetically for a specific nodes.	Checked or 'X' - payload will not be sorted on the report Unchecked or '' - payload will be sorted alphabetically (default value)

Message Selector

Parameter name	Description	Example
PI: Message Search - Interface Name	Used to specify the Interface Name within which the Message Selector should search for the version of the message. This parameter is only to be entered if Interface Name visible in the Message Monitor main screen differs from the Interface Name used to create the object definition.	If we only have receiver interfaces visible in the message monitor, then use the receiver name specified in the ICO of the sender interface specified in the automation object used.
PI: Message Search - Namespace	Used to specify the Interface Namespace within which the Message Selector should search for the version of the message. This parameter is only to be entered if Interface Namespace visible in the Message Monitor main screen differs from the Interface Namespace we have used to create the object definition.	The same condition as the previous parameter but then for the namespace of the receiver interface

Backend Systems

Parameter name

Description

Example

Backend system line for current doc.

This parameter points out the system where the reference backend document is stored. The value should be a system line described in the landscape configuration.

Note:

If Backend system line for the current doc. has the same value as the Backend system line for the reference doc. (for instance, both are S4/HANA) then the RFC connection between the systems will be maintained both in:

a) the original environment of the reference document (for instance, production system)

b) the environment where the current test case execution takes place (for instance, development system)

If Backend system line for the current doc. is different than the Backend system line for the reference doc. then, the RFC connection will be maintained only in the environment of the current execution (for instance, development system), but for both system lines (like ECC and S4HANA)

ECC

SAP_ERP

Backend system line for reference doc.

This parameter points out the system line where Int4 Suite should create test documents during test case execution. In most cases, reference documents and documents created during current test execution are stored in the same system line. However, suppose Int4 Suite is used in a migration scenario (for example, migration from ECC to S4/HANA). In that case, the documents might be created in the new system and then compared with the references from the old system.

The value should be a system line described in the landscape configuration.

Note:

If Backend system line for the current doc. has the same value as the Backend system line for the reference doc. (for instance, both are S4/HANA) then the RFC connection between the systems will be maintained both in:

a) the original environment of the reference document (for instance, production system)

b) the environment where the current test case execution takes place (for instance, development system)

If Backend system line for the current doc. is different than the Backend system line for the reference doc. then, the RFC connection will be maintained only in the environment of the current execution (for instance, development system), but for both system lines (like ECC and S4HANA)

S4HANA

Variables

Variables are the container for values that can be used during testing. Each variable contains two values, the one that is calculated based on the reference message/document and the one that is calculated ad-hoc during test case execution.

Variables & Variable processing

Create button allows variable creation.

Parameter name	Description	Example
Name	Variable technical name	VARIABLE_1
Description	Free text for variable description	Variable One
Type	Type of variable processing	Read & Replace Find message Custom
Scope	Scope determines the processing of procedures that generate unique values like, e.g., GUID or NUM_RANGE. Test Case Scope - variable is replaced with new values considering values from the currently processed test case. The variable value, which occurs multiple times in the test case payload, is replaced with the same new value. The variable value in different test cases from the currently processed test run is replaced with a new value for each test case. Test Run - variable is replaced with new values considering values from the currently processed test run. The variable value in different test cases from the currently processed test run is replaced with the same new value.	Test Case Test Run

Payload Validations

Output payloads after processing by SAP PI/PO are validated against previously stored references. This configuration enables adding rules with exceptions that will allow for differences.

File Type	Processing
XML	XPath
JSON	JSONPath
Flat Files, X12, EDIFACT	Int4 Flat File Syntax or REGEX

Parameter name	Description	Example
Description	Free text for the exception rule	Field1
Expression Type	Expression type. Available options: unspecified XPath Flat expression This field is optional for all interfaces where there is a single type of output. However, for interfaces that output might be both XML and flat file, it is mandatory to specify the expression type.	XPath
Expression	Path pointing to the field/node where the exception should be applied.	//ORDER/DATE/text() (XPATH expression) or START_TAG(BGM+220+)&&END_TAG(+)&& (Flat file expression) or $.order.date (JSONPath expression) REGEX(BGM\+220\+(.)\+) (REGEX expression)*
Rule	Rule to be applied to the field.
Warning	Marks the compared fields with yellow color as a "warning".
Warning when different based on variable replacement	In case compared values are different Int4 Suite compares them with specified variable. If reference/current value pair from comparison matches variable values result is marked as "warning". Variable name used for checking the values has to be specified in the Processing Parameter column.
Warning when different based on value mapping object	In case compared values are different Int4 Suite compares them with specified values in the Mapping Object. If reference/current value pair from comparison matches mapping values result is marked as "warning". Mapping Object name used for checking the values has to be specified in the Processing Parameter column.
Ignore	Even if it is different in the content, it is not highlighted.
Parameter	Used in correlation with Warning Rules.

Payload Matching

In scenarios with multiple outputs for the same receiver, there is a need to compare them based on the same order as reference documents used for test case creation.
Integration Platforms don’t guarantee that outputs will always be sent in the same order control; therefore, the solution is to sort the messages before comparison.

Parameter name	Description	Example
Rule	Free text for rule name	Rule1
Expression Type	Expression type. Available options: unspecified XPath Flat expression This field is optional for all interfaces where there is a single type of output. However, for interfaces that output might be both XML and flat file, it is mandatory to specify the expression type.	XPath
Expression	Path pointing to the field/node where the exception should be applied.	//ORDER/DATE/text() (XPATH expression) or START_TAG(BGM+220+)&&END_TAG(+)&& (Flat file expression) or $.order.date (JSONPath expression) REGEX(BGM\+220\+(.)\+) (REGEX expression)*
Rule Type	Rule type. Available options: Exact match - value from reference and current payload has to be the same Variable - value from reference and current payload is compared based on variable values and variable replacement Mapping object - value from reference and current payload is compared based on mapping object value replacement
Parameter	Depending on Rule type: variable name or mapping object name
Group	Free text grouping field. All rules with from the same group have to be fulfilled to match payloads. At least one group has to be fulfilled to match payloads. Rules within group are linked with AND operator. Groups are linked with OR operator.

Execution Settings

Parameter name

Description

Example

Debug Log

Int4 Suite will provide additional, more technical information in Test Execution Report during the running of the test cases if this parameter is set. Therefore, it is recommended to set this option initially and deactivate it when object definition is confirmed after executing the first test cases

Display wait popup before validation

Wait Flag indicating if Int4 Suite should stop test case execution after sending test case message to middleware. Int4 Suite will show the confirmation box, and the user will decide to continue. This setting can execute manual follow-up actions before running the next test case or checking the validations.

This setup works only with Execute via SAP GUI option of execution

Delay between execution and validation

Parameter name	Description	Example
For each test case	Delay (in seconds) between test case execution ( sending message) and checking the results.	10
Once per test run	Delay (in seconds) between test run execution ( sending messages) and checking the results.	60

Data Scrambling

A scramble list is a part of an automation object. For compliance purposes, for example, GDPR purposes, it's required to hide some of the test case fields. Thanks to the anonymizer feature, it's possible to select fields that hold sensitive values and decide what action should be taken to prevent them from being compromised.

Parameter name	Description	Example
Rule Type	Rule type. Available options: Test Case Creation - in case you want to scramble data during the creation of a test case Runtime - in case you want to scramble data during runtime - when the interface is executed, and additional data is loaded to test case data.	Test Case Creation
Rule	Specify scrambling rule name for identification.	NAME
Method	Choose a scrambling method from a list. Available methods: CONSTANT Replace value with constant The current value will contain the constant passed in the parameter. The constant should be provided as is without any brackets. GUID Generate GUID Generate random value in a GUID format. RANDOM Generate a random value Generates a random value. The value of the parameter defines the upper limit of the range. It is also possible to generate negative numbers. For example, passing -100 in parameter will generate random numbers from -1 to -100 HASH create a hash based on value Calculates a hash based on the given value using algorithm passed in parameter (default 'SHA1'). MASK - replace each character with constant Replace each character with a constant passed in parameter. For example, passing X in the parameter will replace scrambled data with X signs. CUSTOM - create custom method create a CUSTOM method (implementing an interface /INT4/IFTT_IF_DATA_SCRMBL_METH).	HASH
Expression Type	Expression type. Available options: unspecified XPath Flat expression This field is optional for all interfaces where there is a single type of output. However, for interfaces that output might be both XML and flat file, it is mandatory to specify the expression type.	XPath
Expression	Path pointing to the field/node where the exception should be applied.	//ORDER/DATE/text() (XPATH expression) or START_TAG(BGM+220+)&&END_TAG(+)&& (Flat file expression) or $.order.date (JSONPath expression) REGEX(BGM\+220\+(.)\+) (REGEX expression)*
Parameter	Specify Processing Parameter suitable for a chosen scrambling method.	X (for Mask method), SHA1 (for HASH Method)

XSLT Transformations

XSLT Transformation can be applied on both Input and Output payloads and it is stored in a reference test case of type XSLT Transformation. To call XSLT Transformation during Test Case execution, Test Case number that is of type XSLT Transformation needs to be provided as an input to one of the below parameters.

Parameter name	Description
Execute XSLT on ref. output payload	Run XSLT Transformation on output reference message (output stored in Test Case as reference)
Execute XSLT on cur. output payload	Run XSLT Transformation on current output message (output generated during Test Case execution)

Example usage of XSLT transformations can be found here XSLT transformation examples | Different order of XML nodes in a new solution.
