• What is the cause and solution for SAP error message CI_QUICKFIX_FAILED128 - Do not replace inside string templates ?

  The SAP error message CI_QUICKFIX_FAILED128 with the description "Do not replace inside string templates" typically occurs in the context of ABAP programming, particularly when dealing with string templates. This error indicates that there is an attempt to perform a replacement operation within a string template, which is not allowed.
  Cause:
  The error arises when you try to use the replacement operator (&&) within a string template. String templates in ABAP are designed to be a more readable way to concatenate strings and include variables, but they do not support dynamic replacements within their syntax. For example, if you have a string template like this:
  DATA(lv_name) = 'John'.
  DATA(lv_message) = |Hello, { lv_name }! Welcome to the system.|.
  This is valid, but if you try to do something like this:
  DATA(lv_name) = 'John'.
  DATA(lv_message) = |Hello, { lv_name }! Welcome to the system. { lv_name }|.
  And then attempt to replace { lv_name } dynamically, it will trigger the error.
  Solution:
  To resolve this error, you should avoid using replacements within string templates. Instead, you can concatenate strings using the CONCATENATE statement or use multiple string templates without trying to replace within them. Here’s how you can do it correctly:
  
  
  Using Concatenation:
  DATA(lv_name) = 'John'.
  DATA(lv_message) TYPE string.
  CONCATENATE 'Hello, ' lv_name '! Welcome to the system.' INTO lv_message.
  
  
  Using Multiple String Templates:
  DATA(lv_name) = 'John'.
  DATA(lv_message) = |Hello, { lv_name }!| && | Welcome to the system.|.
