Hi,
If issue not solved. Try
1. get IDO Cnumber from message failed in SM58. then delete entry in sm58 and try to resend IDOC from we19. (if IDOC status is Green)
2. Some time this issue may occur in consistent SLD entries. like
the Business system may not have the software component related to your IDOC configuration.
So check the sender tab of business system in ID. will it has your IDOC is in outbound interafces list.
if not check SLD --> Busienss system-->installed software
