• What is the cause and solution for SAP error message MC523 - Database views can contain transparent tables only ?

  The SAP error message MC523 ("Database views can contain transparent tables only") typically occurs when you are trying to create or modify a database view in the SAP system that includes non-transparent tables, such as pooled tables or cluster tables. In SAP, database views are designed to work with transparent tables, which are the standard table type that directly corresponds to a database table.
  Cause:
  
  Inclusion of Non-Transparent Tables: The primary cause of this error is the inclusion of one or more non-transparent tables (pooled or cluster tables) in the database view definition.
  Incorrect Table Type: The view is attempting to join or reference tables that do not meet the criteria for database views.
  
  Solution:
  To resolve the MC523 error, you can take the following steps:
  
  
  Check Table Types: Review the tables included in your database view. Ensure that all tables are transparent tables. You can check the table type in the Data Dictionary (transaction SE11) by looking at the table's attributes.
  
  
  Modify the View Definition:
  
  If you find non-transparent tables in your view, you will need to remove them from the view definition.
  If you need to include data from pooled or cluster tables, consider creating a different type of view, such as a join view or a projection view, if applicable.
  
  
  
  Create Separate Views: If you need to work with data from both transparent and non-transparent tables, consider creating separate views for each type and then combining the results in your application logic.
  
  
  Use Alternative Data Retrieval Methods: If the data from non-transparent tables is essential, you might need to use alternative methods to retrieve that data, such as using ABAP programs or function modules that can handle the data appropriately.
