• What is the cause and solution for SAP error message CNV_OR_PE_GEN028 - ABAP line exceeds max. length of allowed characters (max. length = 255) ?

  The SAP error message CNV_OR_PE_GEN028 indicates that an ABAP line of code exceeds the maximum allowed length of 255 characters. This error typically occurs during the execution of a program or report that processes data, especially in the context of data migration or conversion scenarios.
  Cause:
  
  Long Code Lines: The most common cause is that a line of ABAP code (such as a SELECT statement, string concatenation, or a long comment) exceeds the 255-character limit.
  Data Processing: If you are working with data that is being processed in a loop or through a function module, the data being handled may inadvertently create long lines of code.
  Concatenation: When concatenating strings or building dynamic SQL statements, the resulting line may exceed the limit.
  
  Solution:
  
  Break Down Long Lines: Review the ABAP code and break down any long lines into shorter segments. For example, if you have a long SELECT statement, consider breaking it into multiple lines.
  SELECT field1, field2, field3
    INTO TABLE @DATA(result)
    FROM your_table
    WHERE condition1 = value1
      AND condition2 = value2.
  
  Use String Templates: If you are constructing long strings, consider using string templates or concatenation methods that allow for better readability and maintainability.
  DATA(lv_long_string) = |This is a long string that needs to be split into multiple lines.|.
  
  Check for Comments: Ensure that comments in the code do not exceed the limit. If necessary, split comments into multiple lines.
  Review Function Modules: If the error occurs in a function module, check the parameters being passed and ensure they are not too long.
  Debugging: Use the debugger to identify the exact line of code causing the issue. This can help you pinpoint where the length exceeds the limit.
  
  Related Information:
