How To Fix RLFW002 - After import method &1 uses qRFC or bgRFC.

SAP Error Message - Details

• Message type: E = Error

• Message class: RLFW - Messages for runlevel framework

• Message number: 002

• Message text: After import method &1 uses qRFC or bgRFC.

What causes this issue?

A source code scan of function &V1& revealed the usage of RFC calls of
the form
'call function <FUNC> in background task'
or
'call function <FUNC> in background unit'
Such calls will not be executed in 'Zero Downtime Maintenance'
upgrades(ZDO). The reason is that the above RFC variants are disabled in
the upgrade systems on which the after import methods (AIM) are
executed.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Remove any calls of the above RFC variants from the AIM to ensure that
data changed by the AIM are consistently handled during upgrades
conducted with the ZDO

• What is the cause and solution for SAP error message RLFW002 - After import method &1 uses qRFC or bgRFC. ?

  The SAP error message RLFW002 typically occurs when there is an issue with the queuing mechanism used in the background processing of Remote Function Calls (RFC) in SAP, specifically when using qRFC (queued RFC) or bgRFC (background RFC). This error can arise during the import of data or when executing certain methods that rely on these queuing mechanisms.
  Cause:
  The error message RLFW002 indicates that there is a problem with the import method that is trying to use qRFC or bgRFC. Common causes include:
  
  Queue Issues: There may be issues with the queue itself, such as it being locked, not being processed, or having entries that are not being executed correctly.
  Configuration Problems: The configuration for qRFC or bgRFC might not be set up correctly, leading to failures in processing.
  Network Issues: Connectivity problems between systems can also lead to failures in executing queued RFC calls.
  Transaction Errors: If there are errors in the transaction that is being processed, it can lead to this error message.
  Authorization Issues: The user executing the method may not have the necessary authorizations to perform the action.
  
  Solution:
  To resolve the RLFW002 error, you can take the following steps:
  
  Check Queue Status: Use transaction codes like SMQ1 (for qRFC) or SMQ2 (for bgRFC) to check the status of the queues. Look for any entries that are stuck or have errors.
  Analyze Logs: Check the application logs (transaction SLG1) for any related error messages that can provide more context on what went wrong.
  Reprocess Queues: If you find entries in the queue that are stuck, you can try to reprocess them. In SMQ1 or SMQ2, you can select the entries and choose to reprocess them.
  Check Configuration: Ensure that the configuration for qRFC and bgRFC is correct. This includes checking the RFC destinations and ensuring that they are properly set up.
  Network Connectivity: Verify that there are no network issues between the systems involved in the RFC calls.
  User Authorizations: Ensure that the user executing the method has the necessary authorizations to perform the action.
  Consult Documentation: Refer to SAP documentation or notes related to qRFC and bgRFC for any specific configurations or known issues.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as SMQ1, SMQ2, SLG1, and SM58 for monitoring and troubleshooting RFC calls.
  SAP Notes: Check SAP Notes for any known issues or patches related to the error message RLFW002.
  SAP Community: Engage with the SAP Community forums for insights from other users who may have encountered similar issues.
  
  By following these steps, you should be able to diagnose and resolve the RLFW002 error effectively. If the problem persists, consider reaching out to SAP support for further assistance.
