while processing C015 - Getting Error 'Reservation 000005089 is already being Processed "

Hello,

I have created a customized Program script which will process  MB1A , MIGO and CO15 simultaneously

MB1A - using BAPI

MIGO and CO15 using BADI

When i process for few records everything works fine. But when i process for 2000 records , after processing i am getting error at C015  "Reservation 000005089 is already being Processed".

I tried with wait time up to 8 seconds after MB1A , still i am getting same error.

Can any one suggest how to fix the issue.

BR,

Murali
