• What is the cause and solution for SAP error message RS2HANA_VIEW021 - Check external SAP HANA view consistency for version A of BW object &1 ?

  The SAP error message RS2HANA_VIEW021 indicates that there is an inconsistency in the external SAP HANA view associated with a BW (Business Warehouse) object. This error typically arises when there are discrepancies between the BW object definitions and the corresponding HANA views that are generated or used for reporting and data modeling.
  Cause:
  
  Changes in BW Object: If there have been changes made to the BW object (like InfoObjects, InfoProviders, or transformations) that have not been reflected in the HANA view, this can lead to inconsistencies.
  HANA View Not Updated: The HANA view may not have been regenerated after changes were made to the underlying BW object.
  Version Mismatch: The error message specifically mentions "version A," which suggests that there may be multiple versions of the BW object, and the HANA view is not aligned with the expected version.
  Transport Issues: If the BW object was transported to a different system without the corresponding HANA view, this could lead to inconsistencies.
  
  Solution:
  
  Check HANA View Consistency: Use the transaction code RS2HANA_VIEW to check the consistency of the HANA view. This transaction allows you to analyze the HANA views associated with BW objects.
  Regenerate HANA Views: If inconsistencies are found, regenerate the HANA views. This can typically be done through the BW modeling tools or by using the appropriate transaction codes (like RS2HANA_VIEW).
  Review Changes: Review any recent changes made to the BW object and ensure that they are correctly reflected in the HANA view.
  Transport BW Objects: If the issue is due to transport, ensure that both the BW object and the HANA view are transported together to maintain consistency.
  Check Versioning: Ensure that you are working with the correct version of the BW object. If necessary, switch to the appropriate version in the BW modeling tools.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as RS2HANA_VIEW, RSA1 (Data Warehousing Workbench), and RSRT (Query Monitor) for further analysis.
  SAP Notes: Check for any relevant SAP Notes that may address specific issues related to HANA views and BW objects. SAP Notes often provide patches or additional guidance for known issues.
  Documentation: Review SAP documentation on BW and HANA integration to understand best practices for maintaining consistency between BW objects and HANA views.
  
  By following these steps, you should be able to resolve the RS2HANA_VIEW021 error and ensure that your BW objects and HANA views are consistent.
