Hello,
you can change process code from ME11(change) to ME10(create), which it will change the FM from IDOC_OUTPUT_ORDCHG to "IDOC_OUTPUT_ORDERSIDOC" . It sends every item, but problem is that it send them with wrong ACTION type as "Create" i.e. '001' rather than 002.
You have to go ME10 user exit and change the action code from '001' to '002'.
Thanks,
Cyrus
