Hello Folks,
I am doing a Proof Of Concept on extension of My Inbox for integrating all the applications in my organization under one approval app. To achieve this I extended the TaskProcessing service (version 2) into my own service and added all the required stuff following the cookbook.
One of the scenario is getting task from HP service manager, for which I implemented by own custom provider in Gateway server by extending the /IWPGW/CL_TGW_TASK_FACADE_ABS class and re-writing the methods as required. After that I completed the SPRO configuration for Task Gateway Providers and defined the software version, Provider, Task Facade Implementation Class, etc.
Next step - I maintained the SAP system alias and defined a new system alias with software version same as defined for my custom provider in the step above.
The issue - My Inbox application was not getting the tasks for default ECC system with scenario specific tiles.This only happens when I have defined a scenario and using that definition in Tile. It was always getting task from the custom provider system. If I say allItems=true it works perfectly.
On debugging I found that the BUILD_SCENARIO_SERVICE_URL always returns the service URL for one system alias.
I re-wrote the build scenario service URL to correct the issue and it is working. Now my question is - is this the correct approach ? Why is the default implementation not able to handle 2 system alias (one SAP and one Non SAP) ??
My re-definition of BUILD_SCENARIO_URL is given below -
DATA:
lv_scn_count TYPE i,
ls_scn_task TYPE /iwpgw/c_tgw_tsk,
lv_service_url TYPE string,
lv_task_id type char40.
CALL METHOD super->build_scenario_service_url

iv_service_tech_name = iv_service_tech_name
