How To Fix RSAU492 - No return value <> 0 allowed in update routines in transfer mode

SAP Error Message - Details

• Message type: E = Error

• Message class: RSAU - Update rules

• Message number: 492

• Message text: No return value <> 0 allowed in update routines in transfer mode

What causes this issue?

The return code was set to <> 0 in routine '&V1&', but the
corresponding data field is updated with MOVE. You therefore can
<ZH>not</> prevent the update of a single data field for certain key
values.

System Response

The load process is terminated.

How to fix this error?

When you update with MOVE, you do not have to update all the data
records. In this case you should use a start routine in the update
rules in which you delete the data records that you do not want to
update from table DATA_PACKAGE. Set the return code for all routines
affecting a data field that is updated with MOVE to 0 (also the
corresponding key field routines).

Procedure for System Administrators

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 RSAU492 - No return value <> 0 allowed in update routines in transfer mode ?

  The SAP error message RSAU492 "No return value <> 0 allowed in update routines in transfer mode" typically occurs during data transfer processes, particularly when using update routines in the context of data extraction or data loading in SAP systems. This error indicates that the update routine has returned a value that is not equal to zero, which is not allowed in the transfer mode.
  Cause:
  
  Update Routine Logic: The update routine may contain logic that results in a non-zero return value. This could be due to an error in the processing logic, such as an exception being raised or a condition not being met.
  Data Issues: There may be issues with the data being processed, such as invalid or unexpected values that cause the update routine to fail.
  Configuration Issues: The configuration of the data transfer process may not be set up correctly, leading to unexpected behavior in the update routines.
  
  Solution:
  
  Check Update Routine Logic: Review the code of the update routine to ensure that it is correctly handling all possible scenarios and that it returns a value of zero upon successful completion. Ensure that any exceptions are handled properly.
  Debugging: Use debugging tools to step through the update routine and identify where the non-zero return value is being generated. Look for any conditions that might lead to an error.
  Data Validation: Validate the data being processed to ensure it meets the expected criteria. Check for any anomalies or unexpected values that could cause the update routine to fail.
  Review Configuration: Ensure that the configuration for the data transfer process is correct. This includes checking the settings for the data source, target, and any transformation rules that may be applied.
  Error Handling: Implement proper error handling in the update routine to ensure that it can gracefully handle unexpected situations and return a zero value when appropriate.
  
  Related Information:
  
  SAP Notes: Check SAP Notes related to the specific error message or the components involved in the data transfer process. SAP Notes often provide insights, patches, or workarounds for known issues.
  Documentation: Review the documentation for the specific data transfer process you are using (e.g., Data Services, BW, etc.) to ensure you are following best practices.
  Community Forums: Engage with SAP community forums or support channels to see if others have encountered similar issues and what solutions they have found.
  
  By following these steps, you should be able to identify the cause of the RSAU492 error and implement a solution to resolve it.
