• What is the cause and solution for SAP error message MODEL120 - Model cache was completely invalidated ?

  The SAP error message "MODEL120 Model cache was completely invalidated" typically occurs in the context of SAP BW (Business Warehouse) or SAP HANA when there is a significant change in the underlying data model or when the system detects inconsistencies in the model cache. This can happen due to various reasons, such as changes in the data source, updates to the InfoObjects, or modifications in the data model itself.
  Causes:
  
  Data Model Changes: Changes in the underlying data model, such as adding or removing InfoObjects, can lead to the invalidation of the model cache.
  Data Source Changes: If the data source for a query or report has been modified, it may cause the model cache to be invalidated.
  Transport Requests: If a transport request containing changes to the data model is imported, it can invalidate the existing model cache.
  System Updates: Upgrades or patches to the SAP system can also lead to cache invalidation.
  Manual Cache Clearing: Administrators may manually clear the cache, leading to this message.
  
  Solutions:
  
  Rebuild the Model Cache: The model cache will typically be rebuilt automatically when the next query is executed. Users can simply rerun the query to regenerate the cache.
  Check for Changes: Review any recent changes made to the data model or data sources. If changes were made, ensure they are correctly implemented.
  Clear Cache Manually: If necessary, you can manually clear the cache using transaction codes like RSADMIN or RSRT for BW queries. However, this should be done with caution.
  Monitor System Performance: After cache invalidation, monitor the system performance to ensure that the rebuilding of the cache does not lead to performance issues.
  Consult SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that may address specific issues related to cache invalidation.
