syst-cprog not getting set or taking wrong value in parallel processing

Hi Experts,

In User Exit 935, we have a code : " check syst-cprog = 'SAPLKO71' or syst-cprog = 'RKO7KO8G' ".

The part of code after this statement is getting executed if we run the program individually for single records.

But in parallel processing, this piece of code is being bypassed.

Any suggestion, how to correct the issue.

Thanks and Regards,

Vikas
