• What is the cause and solution for SAP error message DDLS459 - With LIKE in compares, only literals allowed on the right ?

  The SAP error message DDLS459 typically occurs in the context of ABAP Dictionary or when working with Data Definition Language (DDL) statements in SAP. This error indicates that there is an issue with the use of the LIKE operator in a comparison where the right-hand side of the comparison is not a literal value.
  Cause:
  The error arises when you attempt to use a variable or a non-literal value on the right side of a LIKE comparison in a DDL statement. In SAP, the LIKE operator is used to compare a field against a pattern, and the right side must be a literal string (e.g., a hardcoded value) rather than a variable or a field reference.
  Example of the Error:
  SELECT * FROM my_table WHERE my_field LIKE my_variable.
  In this example, my_variable is not a literal, which would trigger the DDLS459 error.
  Solution:
  To resolve this error, you need to ensure that the right side of the LIKE comparison is a literal string. Here are a few approaches to fix the issue:
  
  
  Use a Literal Value: Replace the variable with a literal string that you want to compare against.
  SELECT * FROM my_table WHERE my_field LIKE 'some_pattern'.
  
  
  Dynamic SQL: If you need to use a variable for dynamic comparisons, consider using dynamic SQL (e.g., using EXECUTE IMMEDIATE in ABAP) where you can construct the SQL statement as a string and execute it.
  
  
  Use a Different Comparison: If the use of LIKE is not strictly necessary, consider using other comparison operators that allow variables, such as = or IN.
  
  
  Related Information:
  
  Documentation: Refer to the SAP Help Portal or ABAP documentation for more details on the LIKE operator and its usage.
  ABAP Development: If you are working in an ABAP environment, ensure that you are familiar with the syntax and limitations of SQL statements in ABAP.
  Testing: Always test your changes in a development environment before moving to production to ensure that the logic works as expected.
  
  By following these guidelines, you should be able to resolve the DDLS459 error and successfully execute your SQL statements in SAP.
