I am having this error pop up very frequently on some new SAP systems. This will randomly happen and keep us from being able to release transports and import them in STMS. I receive the following error:
There was an attempt to start the transport control program tp using the local RFC interface.
An error occurred here.
Error code: 4
RFC error text: timeout during allocate / CPIC-CALL: 'ThSAPCMRCV'
- When I check the Transport Tool (STMS: import queue> check> transport tool) I get the following information:
timeout during allocate / CPIC-CALL: 'ThSAPCMRCV' : cmRc=20 thRc=456#Time
out during connection setup (check that partner exists
- When checking the TP System Log I receive the same error. The RSTPTEST report does not give any additional information. SM21 shows a warning and an error:
Warning:
Communication Error, CPIC return code 020, SAP Return code 456
Dialog Process No. 000
Problem cl: SAP web AS problem
Package: STSK
Further Details:
Module Name: thxxhead
Line: 7488
Error Text: 020456
Caller: ThRecei
Error:
Problem cl: transaction problem
Package: STTO
All of these errors are only pointing to a time out. I cannot figure out why this is happening. I checked the TMS RFC connection in SM59 and they are fine. I have been able to work around this issue in 2 different ways. First, I can delete the files in the "\trans\tmp" directory on the server. Sometimes this resolves the error. Else I have to restart the system.
I need to understand where this issue is coming from and how to resolve it. It is becoming more and more frequent. Thank you for your help!
