Hi ,
We faced a similar issue in our landscape.
Our transport path looks as below
Dev --> Virtual system --> after approval in STMS_QA --> QAS
After approving the transport in STMS_QA , we were not able to see the transport in QAS. The RSTMS_DIST_APPROVED_REQUESTS job failed telling 'Could not find delivery route for client(000) in (virtual system name)'.
When we checked the virtual system buffer, we found a transport for client 000. Yet , our delivery route was configured only for client 100. So the job was failing to forward any transport as it couldn't find any delivery route for client 000 transport. We deleted the 000 client transport from the buffer and rescheduled the job. Then the trasnport requests were moving to the subsequent buffers successfully.
Thanks,
Kasi Gupta
