You can save records into a DB table.

Create A DB dtab table with table with components of the return table of the function module.

After the function module completes successfully.

Add code to

Loop after the return table of the FUN module

itab--> internal table

istr line of itab

loop at itab into istruc

append istruc to dtab.

if sy-subrc <>0

error.

ENDLOOP

Hi,

Are you using a "starting new task" approach??

If this is the case, have you tried the addition "PERFORMING ..... ON END OF TASK"??

You most declare a routine as follows


form process_results.
......
.....

RECEIVE RESULTS FROM 'FUNCTION_MODULE'.

.....
....

endform.

Doing this, your calls to the FUNCTION_MODULE may look like this:


Call function 'FUNCTION_MODULE' starting new task g_taskname
destination in group g_group
performing process_results on end of task
.....
....

With this you can process the return table.

I hope this may help you.
