'Missing parameter with PERFORM' error with a function IN BACKGROUND TASK

[Former Member]

I am getting this error when calling a custom function in MIGO user exit ZXMBCU01. When I remove the 'IN BACKGROUND TASK' the function works fine and there are no error messages. When using 'IN BACK...' you can't debug within it to see where the message comes from. I see the message with SM58. I am working in an sap 4.7 environment. I have not found any solutions from google searches.

Here is the statement within ZXMBCU01:

CALL FUNCTION 'Z_UPDATE_MATERIAL_AVAIL_STATUS' IN BACKGROUND TASK

EXPORTING

work_order = xmseg-aufnr.

Here is the code for the function:

Hi,

CALL FUNCTION 'Z_UPDATE_MATERIAL_AVAIL_STATUS' IN BACKGROUND TASK

EXPORTING

work_order = xmseg-aufnr.

Check whether XMSEG-AUFNR is as same type of AUFK-AUFNR?

Please check if the Function Module has been declared as RFC enabled. Check in the Attributes tab page of the Function Module.

Please let me know how this issue has been resolved.

Hello,

Maybe you also need to include the destination? Here's how we use it:

call function 'Z_CS_WEB_DO_BACKGROUND_MOVEINS'

in background task

destination 'NONE'

tables

pe_premises = i_premises.

And, the function module itself is marked as RFC-enabled as the previous poster suggested.

I'd be starting a process of elimination... perhaps start with an "exit." right after

SELECT SINGLE objnr 
  FROM aufk
  INTO gv_objnr
  WHERE aufnr = work_order.
exit.  "leave FM NOW

and if that doesn't crash, work down the code down the code in the function e.g. comment out the BAPI_commit call... and / or build a little test harness report to call the Z function in background task... btw, does the ST22 dump point to anything more specific...?
