PI E2E Synchronous test type is responsible for testing synchronous scenarios. In such cases, test validation is based on a receiver system response message and optionally on the documents created in SAP Backend.
The receiver system will not be virtualized. The connection must be working. The test validation will be performed based on the response from the receiver (after mapping in SAP PI/PO).

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. | http://webshop.com |
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 |
Database Validations
Parameter name | Description | Example |
Database validation ruleset | Reference database validation ruleset object name. Database validation ruleset specify how related backend validation should be performed. Specify tables, fields and join conditions for the backend validation. Buttons allow navigation to the chosen database validation ruleset and creation of a new database validation ruleset | GENERIC_SO |
|---|
Dynamic Columns
Dynamic Column Set field allows to assign previously defined set to an Automation Object. A dynamic column set defines additional, custom columns in the result list of message selector.
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 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 | |
JSON | |
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:
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. | |
| Marks the compared fields with yellow color as a "warning". | |
| 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. | |
| 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. | |
| 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:
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) |
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 |
Number Ranges
The number ranges allow generating new values for variables. Those values are used to substitute original document numbers or other values in reference messages.
The number range used to replace the source system document number should always be configured to not overwrite the original number. It means that documents generated by Int4 Suite should have their own subset of the original document number. Usually, it might be a subset of the upper limit of the original number range.
It is essential that automated testing with Int4 Suite consume numbers that the source system will generate during manual testing. Additionally, if testing environment data is refreshed from the production system, more documents would be created in the testing environment. If the Int4 Suite number were configured in the same range, it would start creating duplicates.
For example, the original number range for document numbers from the source system is 560000 - 590000. It would be wise to set the Int4 Suite number range from 590000 to 600000. However, suppose the SAP backend system uses an external number range. It is essential to stay in the original range. In that case, the Int4 Suite number range may be set as 585000-590000, which gives space for 5000 testing documents. Using range from upper interval reduces the risk that the number will be overwritten.
Additionally, the good practice is to use prefixes or suffixes that will quickly separate source system documents and the ones created by Int4 Suite. It should always be used when there is no document number validation by the SAP backend.
Each Object Definition can contain an unlimited number of number ranges. This way, each variable declared in an object can use its specific number range.
Parameter name | Description | Example |
Number range | Provide a name for the number range. This name would be passed as a parameter in variable processing for actions that will generate values from it. | NUM_RAN |
|---|---|---|
Prefix | The alphanumeric characters to be appended at the beginning of the document number to separate original documents from source systems and the one created during Int4 Suite testing (optional). | INT4_ |
Low value | The first number of our range. | 1 |
High value | The last number of our range. | 999999 |
Current value | When the number range is used during testing, it would increment per each use. | 23 |
Suffix | The alphanumeric characters to be appended at the end of the document number to separate original documents from source systems and the one created during Int4 Suite testing (optional). | _TEST |
Add zeros | If this box is checked, zeros will be automatically appended to the beginning of the document number, such as 000500. | |
Incr. per Test Run | If this indicator is selected, the number range is incrementing once per test run. If multiple test cases with the same Automation Object exist in the test run, they will receive the same value. |
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 |
|---|---|---|
Rule | Specify scrambling rule name for identification. | NAME |
Method | Choose a scrambling method from a list. Available methods:
| HASH |
Expression Type | Expression type. Available options:
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) |
Test Case Creation

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 input message from Java persistence | This flag needs to be checked in the case when the ABAP stack PI read a message from the JAVA adapter | |
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 |
Inject using PIT | This flag will use SAP PIT WS as a message injector (SAP PO > 7.5 SP14) for this automation object. This flag can be set up also globally for whole environment. | |
|---|---|---|
HTTP RFC Destination | Alternative RFC Connection where the REST message should be sent. If this parameter is populated, then the message will be sent there alternative RFC. | SAPSYS1_RFC |
Direct HTTP URL | Direct endpoint to tested interface (synchronous). Additionally, if the URL is dynamic (like JSON queries), it is possible to enter the variable name in {} brackets. The value will be substituted before calling the final URL | /RESTAdapter/webshop/salesOrder/ |

PI: Reference Sender Channel Name | Name of the sender channel to be used as a reference. | CC_SOAP_SENDER |
PI: Reference Sender Channel BC | Business Component of the sender channel to be used as a reference. | BC_SENDER |
PI: Reference Sender Channel Party | Party of the sender channel to be used as a reference. | SENDER_PARTY |
Flag for Flat File interfaces | Used to mark interface input as Flat File | |
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 | CLRF |

Test Case Validation
Parameter name | Description | Example |
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 correct order (unsorted) | This flag determines if the file lines in the XML Comparison Report should be displayed unsorted 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 |
