In an already live PI 7.0 environment we have several Proxy to JDBC XI interfaces that work fine and post data to an external SQL Database from SAP R/3. In one of them we get the following error in RWB Message Monitoring the last 2-3 weeks "JDBC message processing failed; reason ERROR_UNKNOWN_PAYLOAD_FORMAT;0"
That's really strange because the interface runs successfully most of the times that it is executed within the day except for a couple of times. To me it seems that it is a data format error. In SXI_MONITOR everything is ok, the error occurs on the JDBC adapter side. Even if I try to resend the message via Message Monitoring there is no luck, I cannot display the content of the messag/payload from the Audit Log that is posted to the SQL Database.
No upgrade took place on the PI system recently.
