• What is the cause and solution for SAP error message RSAWBN021 - Cannot delete &1 because of lower-level objects ?

  The SAP error message RSAWBN021 indicates that you are trying to delete a higher-level object (like a DataSource, InfoSource, or other objects) that has dependent lower-level objects associated with it. This is a common issue in SAP BW (Business Warehouse) when there are dependencies that prevent the deletion of an object.
  Cause:
  The error occurs because:
  
  The object you are trying to delete has one or more dependent objects that rely on it. For example, if you are trying to delete a DataSource, there may be InfoProviders, transformations, or other objects that are using this DataSource.
  The system enforces referential integrity, which means it will not allow the deletion of an object if it would leave other objects in an inconsistent state.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Identify Dependent Objects:
  
  Use transaction codes like RSA1 (Data Warehousing Workbench) to check for dependent objects.
  Navigate to the object you are trying to delete and look for any associated objects (like InfoProviders, transformations, etc.).
  
  
  
  Delete or Modify Dependent Objects:
  
  If you find dependent objects that are no longer needed, you can delete them first.
  If the dependent objects are still required, consider modifying them to remove the dependency on the object you want to delete.
  
  
  
  Check for Active Objects:
  
  Ensure that there are no active objects that are using the object you want to delete. You may need to deactivate or delete these active objects first.
  
  
  
  Use the Object List:
  
  In some cases, you can use the object list feature in the Data Warehousing Workbench to see all objects related to the one you are trying to delete.
  
  
  
  Consult Documentation:
  
  If you are unsure about the dependencies, consult the SAP documentation or your system administrator for guidance on how to safely remove the object without affecting other components.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as RSA1, SE11 (Data Dictionary), and SE80 (Object Navigator) to navigate and manage objects in SAP BW.
  SAP Notes: Check for any SAP Notes related to the specific object type you are dealing with, as there may be known issues or additional guidance provided by SAP.
  Backup: Always ensure you have a backup or a way to restore objects before making deletions, especially in production environments.
  
  By following these steps, you should be able to resolve the RSAWBN021 error and successfully delete the object in question.
