• What is the cause and solution for SAP error message RSAN_WB098 - Deleting invalid projection for field &1 ?

  The SAP error message RSAN_WB098 indicates that there is an issue with a projection in the SAP BW (Business Warehouse) system. Specifically, it refers to the deletion of an invalid projection for a field. This typically occurs when there are inconsistencies or issues with the data model, particularly in the context of InfoObjects, InfoProviders, or transformations.
  Cause:
  
  Invalid Projections: The projection for a specific field may have become invalid due to changes in the underlying data model, such as the deletion or modification of InfoObjects or InfoProviders.
  Data Model Changes: If there have been recent changes to the data model (e.g., changes in InfoObjects, InfoProviders, or transformations), it can lead to inconsistencies that trigger this error.
  Transport Issues: If changes were transported from one system to another (e.g., from development to production), and the transport did not include all necessary objects, it could lead to invalid projections.
  Inconsistent Metadata: Metadata inconsistencies can arise from manual changes or errors during data modeling.
  
  Solution:
  
  Check the Data Model: Review the data model to ensure that all InfoObjects and InfoProviders are correctly defined and that there are no missing or invalid objects.
  Rebuild Projections: If the projections are invalid, you may need to delete the invalid projections and recreate them. This can often be done through the Data Warehousing Workbench (transaction RSA1).
  Activate Objects: Ensure that all relevant objects (InfoObjects, InfoProviders, transformations) are activated. Sometimes, simply reactivating the objects can resolve the issue.
  Check Transport Requests: If the issue arose after a transport, verify that all necessary objects were included in the transport request and that they were successfully imported into the target system.
  Use Repair Tools: SAP provides tools to help repair inconsistencies in the data model. You can use transaction RSBAS000 to check for inconsistencies and repair them.
  Consult SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that may address this specific error or provide additional guidance.
