• What is the cause and solution for SAP error message RS2HANA_CHECK021 - Existence and assignment of SAP HANA procedure(s) ?

  The SAP error message RS2HANA_CHECK021 typically indicates an issue related to the existence and assignment of SAP HANA procedures in the context of SAP BW/4HANA or SAP BW on HANA. This error often arises during the activation or execution of data models, where the system is unable to find the required HANA procedures that are supposed to be linked to the data model.
  Cause:
  
  Missing HANA Procedures: The required HANA procedures that are supposed to be generated or assigned to the data model do not exist in the HANA database.
  Incorrect Assignment: The data model may be incorrectly configured, leading to a mismatch between the model and the expected HANA procedures.
  Transport Issues: If the HANA procedures were transported from another system, there may have been issues during the transport process that resulted in missing or incomplete procedures.
  Version Mismatch: There may be a version mismatch between the BW/4HANA system and the HANA database, leading to compatibility issues.
  
  Solution:
  
  
  Check Existence of Procedures: 
  
  Log into the SAP HANA database using HANA Studio or HANA Database Explorer.
  Check if the required procedures exist in the appropriate schema. You can do this by executing SQL queries to list the procedures.
  
  
  
  Recreate Missing Procedures: 
  
  If the procedures are missing, you may need to regenerate them. This can typically be done by reactivating the data model in the BW system.
  Go to the BW modeling tools, find the data model, and try to activate it again.
  
  
  
  Review Assignments: 
  
  Ensure that the data model is correctly assigned to the corresponding HANA procedures. Check the settings in the BW modeling tools to confirm that the mappings are correct.
  
  
  
  Transport Validation: 
  
  If the procedures were transported, validate the transport logs to ensure that all objects were transported successfully. If there were errors, you may need to re-transport the objects.
  
  
  
  Check for Updates: 
  
  Ensure that both the BW/4HANA and HANA database are updated to the latest support package or version, as updates may contain fixes for known issues.
  
  
  
  Consult Documentation: 
  
  Refer to SAP Notes and documentation related to your specific version of BW/4HANA and HANA for any known issues or additional troubleshooting steps.
