I have an inbound IDOC (from PI7.3 into my R/3 system RED) that is failing in the SAP PI and in RWB it can be seen with this error.
Message processing failed. Cause:
javax.resource.spi.EISSystemException: com.sap.conn.jco.JCoException: (104)
JCO_ERROR_SYSTEM_FAILURE: No service for system TRFCSAPPID, client in
Integration Directory (raised by system RED|RHIHSAPDCI01) Message 601 of class
IDOC_ADAPTER type A, Par: TRFCSAPPID
The TRFCSAPPID is the R/3 WE20 TRFC PORT.
The IDOC EDI_DC40 Sender Profile
SNDPOR = TRFCSAPPID
SNDPRT = LS
SNDPRN = WENCO
and Receiver parts
RCVPOR = SAPRED
RCVPRT = LS
RCVPRN = REDCLNT110
(I have created a test IDOC in R/3 via WE19 just to make sure that the IDOC would find the partner profile and process the IDOC - and this had the same settings, SNDPOR etc as above. That works.)
However when an IDOC is sent from SAP PI7.3 into R/3 it fails with that JcoException.
What is causing that error?
