Thanks for the response Vadamalai.
You are suggesting to enhance the code at coding level. Can you please eloborate me more on that. Inbound idoc is not coming to reaching to SAP itself. We are not sure at which level check is happening.
One more thing is if we create custom idoc with z segments, will these z segments also get updated( change in release) while doing next upgrade.
Thanks,
Gowrinath.
