Update Task Function Module

[Former Member]

Hi All,

I am trying to update my custom tables using Update Task function module.

FM update task

Insert table A

Insert table B

endFM.

In main program.

Call FM in Update Task.

If sy-subrc = 0.

Commit work.

Endif.

To this FM if I pass a record which already exist in table A. Still the system sets Sy-subrc = 0 after execution of FM. Because of this I am unable to identify whether update is successful or not.

Please help.

Hi Vimal,

Just specifying IN UPDATE TASK will not return any return code to your program as this FM will not run in the same LUW as your program does.

Vimal,

if the INSERT tries to insert an existing key, check for sy-subrc = 4 in the function module, raise an error (duplicate key) and the iupdate process is aborted - you will get express message.

It might be better to

first lock the table

then check the existence of key

then call update function (update process will unlock).

Hi Clémens,

Thanks for the reply. Actually I am going to run this program in batch mode. Will this cause any issue if I raise an exception & if I get express message. Will the processing will be normal for other records.

Thanks,
