Hi Amit,
I would suggest following steps to check:
1. Check whether all data passed from sender system in outbound Idoc if yes then go to step-2 else check why data not getting pass in outbound idoc.
2. Check whether all fields mapped in Idoc structure in receiving system using tcode-WE30.
Please update your response on above 2 checks.
