The tRFC component stores the called RFC function together with the corresponding data in the database of the SAP system, including a unique transaction identifier (TID). If a call is sent, and the receiving system is down, the call remains in the local queue until a later time.

What is the difference between tRFC and qRFC?

qRFC performs a serialization of tRFC (Transactional RFC) using wait queues. While the actual sending process is done by the tRFC, inbound and outbound queues are added to the tRFC, thus resulting in a qRFC (queued Remote Function Call).

What is tRFC error?

– tRFC – Transact Remote Function Call Error, occurs whenever LUW’s (Logical Unit of Work’s) are not transferred from the source system to the destination system.

How do I reprocess tRFC?

1. You can reprocess an tRFC LUW, by selecting the same and by navigating to Edit -> Execute LUW.
2. An LUW can also be debugged by navigating to Edit -> Debug LUW option.
3. In case large number of tRFCs are stuck, all of them can be processed at a time by selecting.
4. Edit -> Execute LUWs option as shown in the above screen.

How does SAP tRFC work?

How does SAP solve tRFC errors?

Execute them by going to menu options –> edit –> Execute LUW(F6). Once all the failed tRFC’s are cleared from the queue, refresh the InfoPackage and it will get successful.

What is SAP SMQ2?

SMQ2 is a transaction code used for qRFC Monitor (Inbound Queue) in SAP. It comes under the package SRFC. When we execute this transaction code, RSTRFCM3 is the normal standard SAP program that is being executed in background.

How do I check my tRFC log?

You can display the log file using transaction SM58. When the calling program reaches a COMMIT WORK, the remote call is forwarded to the target system. All tRFCs with a single destination that occur between one COMMIT WORK and the next belong to a single logical unit of work (LUW).

How do I know if my tRFC failed?

In the same way, search for all those failed tRFC’s as per the noted TID’s. Execute them by going to menu options –> edit –> Execute LUW(F6). Once all the failed tRFC’s are cleared from the queue, refresh the InfoPackage and it will get successful.

How do I check my Trfc log?

How do I monitor transactional RFC in SAP?

Start the Alert Monitor using transaction RZ20 or choose CCMS → Control/Monitoring → Alert Monitor. On the CCMS Monitor Sets screen, expand the SAP CCMS Monitor Templates set. Start the Communications monitor from the list by double-clicking it. Expand the Transactional RFC and Queued RFC subtree.

What is SMQ1 and SMQ2?

SMQ1 – qRFC Monitor for the outbound queue. You use this transaction to monitor the status of the LUWs in the outbound queue and restart any hanging queues manually. ● SMQ2 – qRFC Monitor for the inbound queue. You use this transaction to monitor the status of the LUWs in the inbound queue.
