How to trigger Output Control within Outbound test cases?

Outbound application interfaces based on the SAP Message Control can be tested end to end in Int4 Suite by a single test case. Examples of documents that use the output control in SAP S/4HANA are sales orders, purchase orders, outbound deliveries, or sales invoices.
The test case will verify both the S/4HANA and the integration platform together. Here you can find how Int4 Suite can reprocess interface messages from SAP Output Control.
Testing scope:

The solution is applicable for the below test types:

IDoc Outbound
SAP PI/PO Outbound
SAP CPI E2E Outbound

Below you will find the automation object’s required parameters and variables that will combine repeating the message in output control for the particular business document and capturing its final output message from the integration platform.

Configuration of an automation object:

Create a standard automation object for outbound interface (based on the description for a particular test type)
Setup an Additional Parameter:
Name: Trigger the output from message control (NAST)
Value: X
Add variables that will allow to repeat the message and correlate output based on the final content

Variable Name	Variable Description	Variable processors	Comment

Variable Name	Variable Description	Variable processors	Comment
KAPPL	Output application	Action: Populate Variable Before execution Var. Proc.: CONSTANT Processing Parameter: {Application from NAST}	For example: V1 for sales order, V3 for Invoice etc.
KSCHL	Output Type	Constant as above. Parameter should contain Output Type key	For example: RD00
PARNR	Partner	Constant as above. Parameter should contain Partner Name	Optional
PARVW	Partner Role	Constant as above. The parameter should contain Partner Role	Optional
SPRAS	Language	Constant as above. Parameter should contain Language	Optional
AENDE	Change message flag	Constant as above. Used for testing change messages.	Optional
NACHA	Message transmission medium	Constant as above	Optional
OBJKY	SAP Document number	Two actions: Read variable before execution \| READ_MSG \| {XPath or flat file expression} Locate new message using variable value \| XPATH \| {same XPath or flat file expression}	The same XPath expression should be used for both actions.
NEWSESSION	Trigger output in new session	Constant	Set to 'X' to trigger each output in new RFC session. This is required e.g. in situations when backend logic is implemented in function group and not all global variables are initialized correctly. Triggering multiple outputs in the same session can cause unwanted side effects in such scenarios.
LOCALE	Language of the remote session		Optional Set it to change sy-langu in target system using SET LOCALE statement

The variables' names must be the same. They are used to populate an output in the SAP S/4HANA backend automatically.
First, The OBJKY variable is used to read the business document number that the test case output was captured. Next, the new entry is added to output control, and the interface logic creates a new test message.
Finally, by the second action in the OBJKY variable, Int4 Suite will search the integration platform and find a new message that was produced by the test case execution and contain the correct document number.
