Hi,

I have created a flow service which internally calls an SAP adapter service (to invoke a BAPI).
This flow service is exposed as a webservice.
Ocassionally the flow service is failing with on of the below two errors. If I re-execute the service with the same data, it runs without any error.
ERROR 1:

Is this because of any transient error?***
If so can someone suggest me a way to retry?
