• What is the cause and solution for SAP error message RSMIGR174 - Drop unnecessary DSO MPP views (view suffix 61,62) ?

  The SAP error message RSMIGR174 indicates that there are unnecessary DataStore Object (DSO) MultiProvider (MPP) views with specific suffixes (61, 62) that need to be dropped. This error typically arises during the migration or upgrade process of SAP BW (Business Warehouse) systems, particularly when transitioning to newer versions or when optimizing the data model.
  Cause:
  The error is caused by the presence of obsolete or unnecessary MPP views that are no longer needed in the current data model. These views may have been created during previous configurations or migrations and are not required for the current setup. The suffixes 61 and 62 usually refer to specific versions or types of views that are not compatible or necessary in the new environment.
  Solution:
  To resolve the RSMIGR174 error, you need to drop the unnecessary DSO MPP views with the specified suffixes. Here are the steps to do this:
  
  
  Identify the Views: Use transaction codes like RSA1 (Data Warehousing Workbench) or SE11 (Data Dictionary) to identify the MPP views with suffixes 61 and 62.
  
  
  Check Dependencies: Before dropping the views, ensure that they are not being used by any queries, reports, or other objects in your BW system. You can check for dependencies using the "Where-Used List" functionality in SE11.
  
  
  Backup: It is always a good practice to back up your data and configurations before making changes to the system.
  
  
  Drop the Views: Once you have confirmed that the views are unnecessary, you can drop them using the following steps:
  
  Go to transaction SE11.
  Enter the name of the MPP view you want to drop.
  Select the "Delete" option to remove the view.
  
  
  
  Re-run the Migration: After dropping the unnecessary views, re-run the migration or upgrade process to ensure that the error is resolved.
