• What is the cause and solution for SAP error message RSO_RES_IOBJ020 - Internal error: DataStore object (Units of Measure) could not be deleted ?

  The SAP error message "RSO_RES_IOBJ020 Internal error: DataStore object (Units of Measure) could not be deleted" typically indicates that there is an issue with the deletion of a DataStore Object (DSO) in SAP BW (Business Warehouse). This error can arise due to various reasons, including dependencies, data inconsistencies, or system issues.
  Causes:
  
  Dependencies: The DSO may be linked to other objects, such as InfoProviders, queries, or transformations. If there are dependencies, the system will prevent deletion to maintain data integrity.
  Data Inconsistencies: There may be inconsistencies in the data or metadata associated with the DSO that prevent it from being deleted.
  Authorization Issues: The user attempting to delete the DSO may not have the necessary authorizations to perform the deletion.
  System Errors: Internal errors or bugs in the SAP system can also lead to this message being displayed.
  
  Solutions:
  
  
  Check Dependencies:
  
  Use transaction code RSA1 to access the Data Warehousing Workbench.
  Navigate to the DSO in question and check for any dependencies. If there are dependent objects, you will need to delete or modify them before you can delete the DSO.
  
  
  
  Data Consistency Check:
  
  Run consistency checks on the DSO to identify any issues. You can use transaction code RSBAS000 to perform a consistency check.
  If inconsistencies are found, resolve them before attempting to delete the DSO again.
  
  
  
  Authorization Check:
  
  Ensure that the user has the necessary authorizations to delete the DSO. Check the roles and authorizations assigned to the user in transaction code SU01.
  
  
  
  Use Transaction Code:
  
  If the DSO is not being used, you can try to delete it using transaction code RSDS (DataStore Object Maintenance) and see if it allows you to delete it directly.
  
  
  
  System Logs:
  
  Check the system logs for any additional error messages or information that might provide more context about the internal error. You can use transaction code SM21 to view the system log.
