• What is the cause and solution for SAP error message RSOBJS023 - Node &1 (&2) has no key (OBJ_KEY) ?

  The SAP error message RSOBJS023 indicates that a specific node in the SAP BW (Business Warehouse) hierarchy does not have a key (OBJ_KEY) associated with it. This error typically arises when there is an issue with the hierarchy structure or when the data is not properly loaded or maintained.
  Cause:
  
  Missing Key: The node specified in the error message does not have a corresponding key in the database. This can happen if the hierarchy was not properly defined or if the data was not loaded correctly.
  Data Inconsistency: There may be inconsistencies in the data model, such as missing entries in the master data or hierarchy tables.
  Hierarchy Changes: If the hierarchy has been modified (e.g., nodes added or removed) without proper updates to the associated keys, this error can occur.
  Transport Issues: If the hierarchy was transported from one system to another, there may have been issues during the transport process that led to missing keys.
  
  Solution:
  
  Check Hierarchy Definition: Verify the hierarchy definition in the SAP BW system. Ensure that all nodes are correctly defined and that they have the necessary keys.
  Data Load: Re-run the data load process for the relevant InfoObject or hierarchy. Ensure that the data is loaded correctly and that all necessary master data is available.
  Consistency Check: Use transaction codes like RSA1 (Data Warehousing Workbench) to check for inconsistencies in the hierarchy and master data. You can also use the RSD1 transaction to check the InfoObject and its hierarchy.
  Recreate Hierarchy: If the hierarchy is corrupted, consider recreating it. This may involve deleting the existing hierarchy and creating a new one with the correct structure and keys.
  Transport Check: If the issue arose after a transport, check the transport logs for any errors or warnings. Ensure that all necessary objects were included in the transport request.
