• What is the cause and solution for SAP error message DDLS248 - Alias name for parameter & is missing ?

  The SAP error message DDLS248 indicates that there is a missing alias name for a parameter in a Data Definition Language (DDL) statement. This typically occurs when you are trying to create or modify database objects (like tables, views, etc.) and the system expects an alias name for a parameter but does not find one.
  Cause:
  
  Missing Alias: The most common cause is that the DDL statement is missing an alias for a parameter that requires one. This can happen if you are defining a view or a table and forget to provide an alias for one of the fields.
  Syntax Error: There might be a syntax error in the DDL statement that leads to the system not recognizing the alias.
  Incorrect Parameter Usage: The parameter might be used incorrectly in the context of the DDL statement.
  
  Solution:
  
  
  Check the DDL Statement: Review the DDL statement where the error occurred. Ensure that all parameters that require an alias have one defined.
  
  For example, if you have a statement like:
  CREATE VIEW my_view AS SELECT column1, column2 FROM my_table;
  Ensure that if you are using any parameters that require aliases, they are properly defined:
  CREATE VIEW my_view AS SELECT column1 AS alias1, column2 AS alias2 FROM my_table;
  
  
  
  
  Correct Syntax: Make sure that the syntax of your DDL statement is correct. Refer to the SAP documentation or SQL reference for the correct syntax.
  
  
  Use Proper Naming Conventions: Ensure that the alias names you are using follow the naming conventions and do not contain any illegal characters.
  
  
  Test in Smaller Parts: If the DDL statement is complex, try breaking it down into smaller parts to isolate the issue.
  
  
  Consult Documentation: If you are unsure about the parameters and aliases, consult the SAP documentation or help resources for guidance on the specific DDL commands you are using.
