GET Parameter ID in Update-Function-Module

master1980 — Tue, 30 Jun 2026 11:09:18 GMT

I have written a Report in which i I set a parameter ID (= SET PARAMETER-ID Z....).
After this i do an Batch Input (Call Transaction MODE "E") on Transaction CO02 (Change Production Order) and just presses "PRINT" and then "SAVE". Within UPDATE-TASK (CO_VB_ORDER_PRINT).
a Smartform is called. In this Smartform i GET the parameter ID which is unfortunately always empty.

Why is the Parameter ID empty and what would be the best solution?

You can't GET that parameter in a background session. Either store it in a custom table & SESLECT form it or EXPORT to database in the report and IMPORT form database in the batch job.

If you have your Z report like this:

REPORT zreport. SET PARAMETER ID 'ZZ' FIELD 'VALUE'. CALL TRANSACTION 'CO02' MODE 'E'...

and CO02 does:

CALL FUNCTION 'CO_VB_ORDER_PRINT' IN UPDATE TASK... ... COMMIT WORK. " triggers all CALL FUNCTION IN UPDATE TASK asynchronously by default

an update task is created by default (unless SET UPDATE TASK LOCAL runs). It corresponds to a brand new User Session which doesn't access the same memory context. Ref: ABAP Keyword Documentation - Sessions and Memory Areas.

Several solutions:

Force the update task to run in the same User Session via CALL TRANSACTION 'CO02' UPDMODE 'L' (it's equivalent to run SET UPDATE TASK LOCAL at the start of the new user session).
If you need to keep the synchronous or local execution of the update task, you may also pass anything to the memory of the update task by creating a Z update function module which does SET PARAMETER ID 'ZZ' FIELD 'VALUE', calling this function module via CALL FUNCTION 'ZYOURFM' IN UPDATE TASK EXPORTING zz = value before CALL FUNCTION 'CO_VB_ORDER_PRINT' IN UPDATE TASK
As already said, you may use any other solution which stores data in a persistent storage, but the solution is more complex if you want to handle several users running the program at the same time.

Hello @master1980

The parameter ID is empty because SET/GET parameters don’t work across update tasks.
Your SmartForm runs in an update task (different LUW/session), so it cannot access the GET parameter set earlier

Thanks,
