JCO.Server Error while trying to execute a RFC program from SAP
We are connecting to an external registered server program from SAP via Web Methods.
The external server program is registered with the SAP Gateway. We have created a TCP/IP RFC destination and are able to connect to the destination successfully via SM59.
An RFC function is created in SAP and is called using the syntax CALL FUNCTION "/NGN/BAPI_STRE_SEARCH_PROCESS" DESTINATION 'PRDB2B'. We have also handled the COMM_FALIURE and SYSTEM_FALIURE exceptions in the function call.
We are monitoring the gateway via SMGW and see a connection log to the RFC destination as below
Number - 10
LUname - dev01
TPName - sapgw00
User - KRAORANE
Status - CONNECTED
Symbolic - PRDB2B
Conversation - 86520353
Prot - REG
SAP return code - 0
CPIC rtn code - 0
The external program returns results as expected.
However sometimes the RFC fails and returns the message JCO.Server could not create server function /NGN/BAPI_STRE_SEARCH_PROCESS.
We are not able to figure what exactly is causing this error. Any help will be highly appreciated.
