Multiple idocs in Single Job behaves differently (RBDAPP01)

Hi,

How to debug the background Job for Program RBDAPP01 which already posted the Idocs in 53 status from 64.

I wanted to analyze why multiple idocs in same job behave differently than the single idoc in a job. In case of multiple idocs in a single job i put packet size 1, but no help.

Thanks,

Asit Purbey.
