• What is the cause and solution for SAP error message DDLS452 - Obj. with select * cannot be determined, all dependents will be activated ?

  The SAP error message DDLS452 indicates that there is an issue with the activation of a database object, specifically related to the use of the SELECT * statement in the definition of a view or a table. This error typically arises when the system cannot determine the structure of the object due to the use of SELECT *, which can lead to ambiguity in the fields being selected.
  Cause:
  
  *Use of SELECT :* The primary cause of this error is the use of `SELECT ` in the definition of a database view or table. This can create issues when the underlying tables or views change, as the system cannot determine the exact fields that should be included in the view or table.
  Dependent Objects: If there are dependent objects (like other views or programs) that rely on the object being activated, and the system cannot resolve the structure due to the SELECT *, it will raise this error.
  Changes in Underlying Tables: If the structure of the underlying tables has changed (e.g., fields added or removed), it can also lead to this error.
  
  Solution:
  
  
  Modify the Definition: Instead of using SELECT *, explicitly specify the fields you want to include in the view or table definition. This will help the system to clearly understand which fields are being referenced.
  Example:
  SELECT field1, field2, field3 FROM your_table
  
  
  Check Dependencies: Review any dependent objects that might be affected by the changes. Ensure that they are also updated accordingly to reflect the new structure.
  
  
  Re-activate Objects: After making the necessary changes, try to re-activate the object. This can often resolve the issue.
  
  
  Check for Syntax Errors: Ensure that there are no syntax errors in the SQL statement or in the definitions of the objects.
  
  
  Use Transaction SE11 or SE14: You can use transaction codes SE11 (Data Dictionary) or SE14 (Database Utility) to check the definitions of the objects and their dependencies.
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide additional guidance.
  Documentation: Review SAP documentation regarding best practices for defining views and tables, particularly regarding the use of SELECT *.
  Testing: After making changes, thoroughly test the affected objects to ensure that they function as expected and that no other issues arise.
  
  By following these steps, you should be able to resolve the DDLS452 error and successfully activate your database objects.
