We recently upgrade our SAP Data Services from 4.1 SP3 to 4.2 SP4 Patch3. Since then, all the OpenHub jobs start failing intermittently with the below error:
Read status '' could not be set for Open Hub destination at SAP system . Error is: No suitable namespace available.
Here is a normal process flow of the OpenHub jobs.
1. DS job started
2. Dataflow trigger a BW process chain to populate the OpenHub table
3. DS RFC server wait for the read request id
4. DS RFC server receive the read request id and pass to the Dataflow
5. Dataflow set the status with the read request id and start to extract data
6. DS job finish
In the fail instances, we found that after step 3, DS RFC server receive a read request id (0), write it to AL_SAP_JOB, and pass this invalid 0 id to the Dataflow, even though the process chain is still running and has NOT sent back the valid read request id. The Dataflow then try to set the status to a request id 0 which does not exist in BW, and hence the error occur. The BW process chain complete successfully and send back the valid id to DS RFC server, but RFC server does not know how to deal with the valid id already. Below is the RFC logs.

Does any one have the similar issue on OpenHub or have an idea where the 0 read request id is coming from?
Thanks a lot!!
