How To Fix RSQU023 - A consistent delta extraction is not possible

SAP Error Message - Details

• Message type: E = Error

• Message class: RSQU - S-API after 4.0: Delta Queue, Real Time Update

• Message number: 023

• Message text: A consistent delta extraction is not possible

What causes this issue?

Consistent delta extraction is not possible since the system &v2& is
not connected to DataSource &v1&. This system is a BW system with
release 1.2. Detla data can only be distributed to several target
systems if all receiving systems have a BW release of 2.0 or higher.

System Response

The extraction process has been terminated.

How to fix this error?

Delete the assignment of DataSource &v1& to BW system &v2& before you
repeat the extraction process.

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 RSQU023 - A consistent delta extraction is not possible ?

  The SAP error message RSQU023, which states "A consistent delta extraction is not possible," typically occurs in the context of SAP BW (Business Warehouse) when there are issues with delta extraction from a source system. This error indicates that the delta mechanism cannot ensure that the data being extracted is consistent, which can happen for several reasons.
  Causes of RSQU023
  
  
  Inconsistent Delta Queue: The delta queue in the source system may have inconsistencies, possibly due to previous failed delta extractions or issues with the data load process.
  
  
  Data Changes: If there are changes in the data model or if the data in the source system has been modified (e.g., records deleted or updated) after the last delta extraction, it can lead to inconsistencies.
  
  
  Initialization Issues: If the initialization of the delta extraction was not completed successfully, it can cause problems for subsequent delta extractions.
  
  
  Missing Data: If the data that is supposed to be extracted is missing or has been archived, it can lead to this error.
  
  
  Incorrect Delta Settings: The delta settings in the InfoSource or DataSource may not be configured correctly.
  
  
  Solutions to RSQU023
  
  
  Check Delta Queue: Review the delta queue in the source system to ensure that it is consistent. You can use transaction codes like RSA7 to monitor the delta queue.
  
  
  Reinitialize Delta: If the delta extraction is not working due to initialization issues, you may need to reinitialize the delta. This involves performing a full load followed by a delta load.
  
  
  Check Data Consistency: Ensure that the data in the source system is consistent and that there are no missing records. You may need to check for any recent changes in the data model.
  
  
  Review DataSource Settings: Verify the settings of the DataSource in the source system. Ensure that the delta extraction settings are correctly configured.
  
  
  Monitor for Errors: Check for any errors in the process chain or in the data load monitor (transaction LBWQ or RSA1) that might indicate issues with the extraction process.
  
  
  Consult Logs: Review the logs for any additional error messages or warnings that could provide more context about the issue.
  
  
  Contact SAP Support: If the issue persists and you cannot identify the cause, consider reaching out to SAP support for further assistance.
