• What is the cause and solution for SAP error message SDDL_PARSER_MSG028 - Comparison value of LIKE condition must be a character-type literal ?

  The SAP error message SDDL_PARSER_MSG028 indicates that there is an issue with a LIKE condition in a query or selection where the comparison value is not a character-type literal. This typically occurs in the context of SAP's data definition language (DDL) or when working with selection conditions in ABAP programs.
  Cause:
  The error arises when you are trying to use a LIKE condition in a query, but the value you are comparing against is not a string or character-type literal. The LIKE operator is used to compare a string to a pattern, and it expects the comparison value to be a character string.
  Example of the Issue:
  If you have a query like this:
  SELECT * FROM table_name WHERE column_name LIKE some_variable.
  If some_variable is not a character-type literal (for example, if it is a numeric type), you will encounter this error.
  Solution:
  To resolve this error, ensure that the comparison value in the LIKE condition is a character-type literal. Here are some steps you can take:
  
  
  Check Data Types: Verify the data type of the variable or value you are using in the LIKE condition. It should be of type CHAR, STRING, or similar.
  
  
  Convert Data Types: If you are using a variable that is not a character type, convert it to a string type before using it in the LIKE condition. For example:
  DATA(lv_variable) = 'some_value'.
  SELECT * FROM table_name WHERE column_name LIKE lv_variable.
  
  
  Use Character Literals: If you are using a hardcoded value, ensure it is enclosed in single quotes:
  SELECT * FROM table_name WHERE column_name LIKE 'some_value%'.
  
  
  Debugging: If you are unsure about the data type of a variable, you can use debugging tools in SAP to inspect the variable's type and value.

  Data Types in ABAP: Familiarize yourself with the different data types in ABAP, especially character types, to avoid similar issues in the future.
  SAP Documentation: Refer to the official SAP documentation for more details on SQL syntax and data types.
