BADI: /IWPGW/BADI_TGW_TASK_DATA. How it works?

[suwandi_cahyadi]

Hello,

I am on S4 HANA 1610 and I want to change the detail description of the task in the detail screen. I thought that I can use BADI /IWPGW/BADI_TGW_TASK_DATA as stated in this page.

I implemented this both at the front-end server (Fiori Server) and back-end server (S/4 HANA) putting only the TASK_ID in the filter. then I put external break-point for my user at both methods in this BADI (MODIFY_TASK_TITLE, MODIFY_TASK_DESCRIPTION). Somehow the break-point in method MODIFY_TASK_TITLE at the front end server is triggered only if I put select the task that I filter for this BADI on the left section then press refresh at the browser. It is called from method UPDATE_TASK_DETAILS_FROM_CUST of class /IWPGW/CL_TGW_EDP_TASK.

But somehow the MODIFY_TASK_DESCRIPTION is never triggered or I don't know how to trigger that method. I search class /IWPGW/CL_TGW_EDP_TASK for MODIFY_TASK_DESCRIPTION, and I can find it is being called at methods: ENTITY_DESCRIPTION and MAP_FINALIZE_FIELDS_DATA.

I also read in this thread to check IW_PGW support package level. But somehow I couldn't find that component in status in both front-end and back-end server.

The question is, how to get method MODIFY_TASK_DESCRIPTION of BADI /IWPGW/BADI_TGW_TASK_DATA triggered?

Thank you.
