• What is the cause and solution for SAP error message DI774 - Lock mode for table & meaningless since no base table exists ?

  The SAP error message DI774 indicates that there is an issue with the lock mode for a table that does not have a corresponding base table. This typically occurs in the context of database operations where a lock is being requested on a table that is either a view or a non-existent table.
  Cause:
  
  Non-existent Base Table: The error usually arises when the system is trying to lock a table that does not have an underlying base table. This can happen if the table is a view or if the table has been deleted or not properly defined in the database.
  Incorrect Table Name: There might be a typo or an incorrect reference to the table name in the code or configuration.
  Database Issues: There could be issues with the database itself, such as corruption or misconfiguration.
  
  Solution:
  
  Check Table Existence: Verify that the table you are trying to access actually exists in the database. You can do this by using transaction codes like SE11 (Data Dictionary) or SE16 (Data Browser) to check the table definition.
  Review Table Type: If the table is a view, ensure that the underlying base tables exist and are correctly defined. If you are trying to lock a view, consider whether you need to lock the base tables instead.
  Correct Table Name: Double-check the code or configuration where the table is referenced to ensure that the name is correct and matches the actual table in the database.
  Database Consistency Check: If you suspect database corruption, you may need to run consistency checks or consult with your database administrator to resolve any underlying issues.
