• What is the cause and solution for SAP error message MC798 - Table &: DROP statements could not be generated for all dependent views ?

  The SAP error message MC798, which states "Table &: DROP statements could not be generated for all dependent views," typically occurs during the deletion or modification of a database table in the SAP system. This error indicates that there are dependent views that prevent the DROP statement from being executed successfully.
  Cause:
  
  Dependent Views: The primary cause of this error is that there are one or more database views that depend on the table you are trying to drop. SAP does not allow the deletion of a table if there are views that reference it, as this would lead to inconsistencies in the database.
  Database Constraints: There may be constraints or relationships defined in the database that prevent the deletion of the table.
  Authorization Issues: Sometimes, the user executing the operation may not have the necessary authorizations to drop the views or the table.
  
  Solution:
  To resolve the MC798 error, you can follow these steps:
  
  
  Identify Dependent Views:
  
  Use transaction code SE11 (Data Dictionary) or SE14 (Database Utility) to check for dependent views.
  You can also use the SQL command SELECT * FROM DDL_DEPENDENCIES WHERE OBJECT_NAME = '<your_table_name>' to find dependent objects.
  
  
  
  Drop or Modify Dependent Views:
  
  If you find dependent views, you will need to drop or modify them before you can drop the table.
  Use transaction SE11 to delete the views or adjust their definitions to remove the dependency on the table.
  
  
  
  Check for Constraints:
  
  Ensure that there are no foreign key constraints or other dependencies that would prevent the table from being dropped.
  You can check constraints in the Data Dictionary (SE11) under the "Foreign Keys" tab.
  
  
  
  Authorization Check:
  
  Ensure that you have the necessary authorizations to perform the DROP operation on both the table and any dependent views.
  
  
  
  Re-attempt the DROP Statement:
  
  Once all dependent views and constraints have been addressed, you can re-attempt to drop the table.
