Jobdetails/get previous job whitch called report in seperate task

Question

We have 2 reports whitch will call the same function moduls in seperated new tasks and wait for anser.
We use it to work up data in parallel mode. The function module itself call a report
e.g.
        CALL FUNCTION pa_fbnam
           STARTING NEW TASK g_taskname     "Function module to perform in parallel
           DESTINATION IN GROUP pa_group 
           PERFORMING return_info ON END OF TASK
           EXPORTING
               ip_tjob   = g_id_tjob  "jede RFC Instanz bekommt eindeutige ID
               IP_DBS    = pa_dbs     "Kennung der Zieldatenbank
               IP_TASK   = g_taskname
           EXCEPTIONS
             communication_failure = 1 MESSAGE l_msgtxt.
Now the problem is, that the reports call the SAME function moduls. In the function modul we want to know
whitch report called the fm, because we need this info for the report ...
We tried "call stack" info - no chance, we tried import/export to/from memory - no chance
Daoes anyone has an idea, how we can track the 'call parts' or rather say how we can check, whitch report/function calls the new tasks?
thanks a lot
bye

Hi Mike,
Not sure.  I tested it in an ECC6 system as STARTING NEW TASK (function module in same client/application server as calling program) and via a bgRFC from ECC6 to SCM 5.1
In both cases the function returned the calling program details with no problems. 
If your calling program is running on the same application server as your RFC then maybe you could try the EXPORT/IMPORT command with the alternative of either SHARED MEMORY or SHARED BUFFER
export sy-repid to shared buffer indx(st) id 'ZZCALLER'.
where ZZCALLER is any arbitrary name.  In your RFC immediately delete the value (after reading it) by
delete from  shared buffer indx(st) id 'ZZCALLER'.
Unfortunately there could be a minute timing issue with caller A and caller B executing at the same time but this is minimal.
Cheers,
Pete
Addition:
Just a thought to 'help' a little with the timing issue; you could have two id's ZZCALLERA and ZZCALLERB.  Try to import both and by checking the sy-subrc you will know which one was called. Not brilliant but may help depending upon your overall solution design
