• What is the cause and solution for SAP error message DT905 - List of dependent views: ?

  The SAP error message DT905, which states "List of dependent views," typically occurs in the context of data modeling or when working with views in SAP systems, particularly in SAP BW (Business Warehouse) or SAP HANA environments. This error indicates that there are dependent views or objects that are affected by the changes you are trying to make.
  Cause:
  
  Dependent Objects: The error usually arises when you attempt to modify or delete a view that has dependent objects (like other views, queries, or data models) that rely on it.
  Data Model Changes: If you are trying to change the structure of a view (like adding or removing fields) that is being used by other views or reports, the system will prevent this to maintain data integrity.
  Inconsistent State: The system may be in an inconsistent state due to previous changes that were not properly executed or saved.
  
  Solution:
  
  Identify Dependent Views: Use the transaction code or tools available in your SAP environment to identify which views or objects are dependent on the view you are trying to modify. This can often be done through the Data Dictionary (SE11) or the relevant modeling tools.
  Review Dependencies: Once you have identified the dependent views, review their definitions and understand how they are linked to the view you want to change.
  Modify or Delete Carefully: If you need to modify the view, ensure that you also update the dependent views accordingly. If you need to delete the view, you may need to first delete or modify the dependent views.
  Check for Active Queries: Ensure that there are no active queries or reports that are currently using the view. If there are, you may need to deactivate or adjust them before making changes.
  Transport Requests: If you are working in a development environment, ensure that your changes are properly included in transport requests and that they are moved to the appropriate environments (like QA or Production) in a controlled manner.
