SAP Error Message - Details

• Message type: E = Error

• Message class: XC - Message Class for Core Interface

• Message number: 507

• Message text: Error in one of the previous RFCs of the same LUW

What causes this issue?

The system has determined that an error occurred in a previous RFC of
the <DS:GLOS.8554C86B3BAACE42817DEADBB261F52A>qRFC LUW</> being
processed. However, it was only determined during the RFC being
processed that <DS:GLOS.180AC48E4BA2464C960A5297D9F7AAE3>C
handling</> needs to be deactivated.

System Response

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

• What is the cause and solution for SAP error message XC507 - Error in one of the previous RFCs of the same LUW ?

  The SAP error message XC507 indicates that there was an error in one of the previous Remote Function Calls (RFCs) within the same Logical Unit of Work (LUW). This error typically arises in scenarios where multiple RFC calls are made in a sequence, and one of the calls fails, causing subsequent calls to also fail.
  Cause:
  
  
  Previous RFC Failure: The most common cause of the XC507 error is that one of the previous RFC calls in the same LUW encountered an error. This could be due to various reasons such as:
  
  Incorrect data being passed to the RFC.
  Issues with the remote system (e.g., the target system is down or unreachable).
  Authorization issues preventing the RFC from executing successfully.
  Network issues causing communication failures.
  
  
  
  Transaction Rollback: If the previous RFC call resulted in a rollback of the transaction, any subsequent calls in the same LUW will also fail.
  
  
  Solution:
  
  
  Check Previous RFC Calls: Review the logs or trace files to identify which RFC call failed. You can use transaction codes like SM21 (System Log) or ST22 (Dump Analysis) to find more details about the error.
  
  
  Analyze Error Messages: Look for specific error messages associated with the failed RFC call. This will provide insights into what went wrong.
  
  
  Correct Data Issues: If the failure was due to incorrect data, ensure that the data being passed to the RFC is valid and meets the expected format and constraints.
  
  
  Check System Connectivity: Ensure that the target system is up and running, and that there are no network issues preventing communication.
  
  
  Review Authorizations: Verify that the user executing the RFC has the necessary authorizations to perform the requested actions.
  
  
  Re-execute the LUW: After addressing the root cause of the failure, you may need to re-execute the entire LUW to ensure that all RFC calls are processed successfully.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as SM37 (Job Monitoring), SM58 (Transactional RFC), and SLG1 (Application Log) to monitor and troubleshoot RFC issues.
  RFC Configuration: Ensure that the RFC destination is correctly configured in transaction SM59.
  SAP Notes: Check for any relevant SAP Notes that may address known issues related to the XC507 error.
  
  By following these steps, you should be able to identify the cause of the XC507 error and implement a solution to resolve it.
