• What is the cause and solution for SAP error message ACM_SYNTAX044 - Operator LIKE is not permitted for data type &1 ?

  The SAP error message ACM_SYNTAX044 indicates that the LIKE operator is being used with a data type that does not support it. In SAP ABAP, the LIKE operator is typically used for string comparisons, but it cannot be applied to certain data types such as numeric types, date types, or other non-character types.
  Cause:
  The error occurs when you attempt to use the LIKE operator on a field or variable that is not of a character type (e.g., CHAR, STRING, etc.). For example, if you try to use LIKE on a numeric field or a date field, you will encounter this error.
  Solution:
  To resolve this error, you need to ensure that the LIKE operator is only used with compatible data types. Here are some steps you can take:
  
  
  Check Data Types: Review the data types of the fields or variables involved in the comparison. Ensure that they are character types.
  
  
  Convert Data Types: If you need to compare a non-character type with a string pattern, consider converting the non-character type to a string. You can use the CONCATENATE statement or the WRITE statement to convert numeric or date values to strings.
  Example:
  DATA: lv_number TYPE i VALUE 123,
        lv_string TYPE string.
  
  lv_string = lv_number.
  IF lv_string LIKE '12%'.
      " Your logic here
  ENDIF.
  
  
  Use Appropriate Operators: If you are working with numeric or date types, consider using other comparison operators such as =, <>, <, >, etc., instead of LIKE.
  
  
  Review Logic: Ensure that the logic of your program is correct and that using LIKE is indeed necessary. Sometimes, a different approach may be more appropriate.
  
  
  Related Information:
  
  Data Types in ABAP: Familiarize yourself with the different data types in ABAP and their characteristics. This will help you understand which operators can be used with which types.
  ABAP Documentation: Refer to the official SAP documentation for more details on the LIKE operator and its usage.
  Debugging: If you are unsure where the error is occurring, use the ABAP debugger to step through your code and identify the exact line causing the issue.
  
  By following these steps, you should be able to resolve the ACM_SYNTAX044 error and ensure that your code functions as intended.
