• Key Concepts: 
  The substring function in SAP is a built-in function that allows users to extract a portion of a character string. It is part of the BC-ABA ABAP Runtime Environment, which is a programming language used to develop applications for the SAP system. 
  
  How to use it: 
  The substring function can be used to extract a portion of a character string. It takes three parameters: the source string, the starting position, and the length of the substring. The starting position is the index of the first character in the substring, and the length is the number of characters to be extracted. The substring function returns a new string containing the extracted characters. 
  
  Tips & Tricks: 
  When using the substring function, it is important to remember that the starting position and length parameters are zero-based. This means that the first character in the source string has an index of 0, and the length parameter should be one less than the desired number of characters.
