• What is the cause and solution for SAP error message DDLS104 - Random expressions are not supported in a condition ?

  The SAP error message DDLS104 indicates that random expressions are not supported in a condition within the context of Data Definition Language (DDL) operations, particularly when working with database views or table definitions in ABAP Dictionary.
  Cause:
  This error typically arises when you are trying to use a random expression or a non-deterministic function in a condition of a database view or a table definition. In SAP, certain expressions or functions that do not yield a consistent result (like random number generators or functions that depend on external factors) cannot be used in conditions because they can lead to unpredictable results in the context of database operations.
  Solution:
  To resolve this error, you should:
  
  
  Review the Condition: Check the condition that is causing the error. Look for any expressions that may be considered random or non-deterministic.
  
  
  Replace Random Expressions: If you find any random expressions, replace them with deterministic expressions. For example, instead of using a function that generates random values, use fixed values or expressions that yield consistent results.
  
  
  Use Alternative Logic: If your logic requires randomness, consider handling that logic in the application layer (e.g., in ABAP code) rather than in the database view or table definition.
  
  
  Test the Changes: After making the necessary adjustments, test the changes to ensure that the error is resolved and that the functionality meets your requirements.
  
  
  Related Information:
  
  ABAP Dictionary: Understanding how the ABAP Dictionary works can help you design your database views and table definitions more effectively.
  Deterministic vs. Non-Deterministic Functions: Familiarize yourself with the difference between these types of functions, as this knowledge will help you avoid similar issues in the future.
  SAP Documentation: Refer to the official SAP documentation for more details on DDL operations and the limitations regarding expressions in conditions.
