• What is the cause and solution for SAP error message DDLS154 - select * could not be expanded; base table & does not exist ?

  The SAP error message DDLS154 indicates that there is an issue with a database table that is being referenced in a Data Definition Language (DDL) statement. Specifically, the message states that the base table specified does not exist, which means that the system cannot find the table you are trying to access or manipulate.
  Cause
  The error can occur due to several reasons:
  
  
  Table Does Not Exist: The most straightforward reason is that the table you are trying to reference has not been created or has been deleted.
  
  
  Incorrect Table Name: There may be a typo in the table name or the table name may be case-sensitive depending on the database system.
  
  
  Transport Issues: If the table was created in a different system (e.g., development) and not transported correctly to the current system (e.g., production), it may not exist in the current environment.
  
  
  Authorization Issues: The user executing the DDL statement may not have the necessary authorizations to access the table.
  
  
  Database Connection Issues: There may be issues with the database connection that prevent the system from accessing the table.
  
  
  Solution
  To resolve the DDLS154 error, you can take the following steps:
  
  
  Verify Table Existence:
  
  Check if the table exists in the database. You can do this by using transaction codes like SE11 (Data Dictionary) or SE16 (Data Browser) to look for the table.
  
  
  
  Check Table Name:
  
  Ensure that the table name is spelled correctly and matches the case used in the database.
  
  
  
  Transport Check:

  Authorization Check:
  
  Verify that the user has the necessary authorizations to access the table. You can check this in transaction SU53 or by consulting with your security team.
  
  
  
  Database Connection:
  
  Ensure that the database connection is active and functioning correctly. You may need to check with your database administrator if there are any connectivity issues.
