DB Update from BAPI

Question

Hi All,
I am trying to create a RFC FM ( BAPI) which will be called from external system. The role of this FM is insert to 3 different  Z tables.  Table structure's  is like Header, Details & Sub details.
Requirement is if the insert/update fails on Header than all other insert/update should fail  Also i need to report back any errors to calling system.
I have designed the BAPI in such way that after some initial data check, i call another FM in update task.
Inside this FM i am doing insert/update. After coming out i am doing Commit Work. Also setting  SET UPDATE TASK LOCAL
My doubt is
(1) how would this handle a situation where update in header fails so all other update are rejected.
(2)  I would like to let the other system know, if the insert is good or fail. Since Update task does not allow export, how to handle this.
Please advice the best solution for this.

Hello,
I agree with the last post, it's useless to use update task for a simple update process.
But if you want to create a BAPI, then COMMIT WORK is forbidden, the commit is the responsibility of the calling application (by calling BAPI_TRANSACTION_COMMIT by RFC).
Now, if you want to know if the INSERT are okay, just test SY-SUBRC, and return an exporting parameter which gives the status if it's okay or not (if it's a BAPI, that should be parameter RETURN of type table of BAPIRET2). The calling program will then be able to commit or rollback (using BAPI_TRANSACTION_ROLLBACK)
