CALL FUNCTION XXX UPDATE TASK

Hello Experts,

Good Day!

I'm working on a user exit where a couple of existing custom FM is implemented as below, each FM updates different field from table LT_TAB_UPDATE.

CALL FUNCTION XX1 in UPDATE TASK

TABLES = LT_TAB_UPDATE

CALL FUNCTION XX2 in UPDATE TASK

TABLES = LT_TAB_UPDATE

Now, i have a new requirement to update a new field and planning to implement a new FM, i don't want to touch the existing FM's.

CALL FUNCTION XX3 in UPDATE TASK

TABLES = LT_TAB_UPDATE

I cant find anything in the forum if it's allowed to have multiple update task in one LUW but base on debugging it seems that multiple update task doesn't work as expected. Can anyone confirm if this is allowed or not?

Thanks,

Dimmak
