Summary:
You created a transaction launcher to open an ecc transaction from CRM WebUI.
You want to return parameter on exit from ecc transaction and would like to read the parameter in crm.
Solution:
Step1:
Set a global variable with values you want to return from ecc transaction. This could a variable of a function group or SPA/GPA parameters set by SET PARAMETER statement.
Example: In PAI on click of save button of a z transaction which creates new installment plan, set SPA/GPA parameter.
This step may be skipped for standard transactions where the desired return parameter is available in some SPA/GPA parameter.
Step2:
Open business object repository method which is called by TL.
Read the global variable which is set in previous step and set a container element
after the CALL TRANSACTION statement.
Note that bor container element name need not be same as SPA/GPA parameter name.
Step3:
TL handler class which is a subclass of CL_CRM_UI_LTX_ABSTRACT_ITS has access to the protected attribute GR_DATA_FLOW_FROM_ITS.
In process_return method of handler class, read the container of this attribute to get the parameter
gt_container of gr_data_flow_from_its is set in super call of process_return method.
So this call should not be commented.
