  Key Concepts: 
  The escape character function in SAP is a feature of the ABAP Runtime Environment (BC-ABA) that allows users to define a character as an escape character. This character can then be used to escape special characters in strings, allowing them to be used in SQL statements. 
  
  How to use it: 
  To use the escape character function, users must first define a character as the escape character. This can be done by using the SET ESCAPE statement in an ABAP program. Once the escape character is defined, it can be used to escape special characters in strings. For example, if the escape character is set to ‘\’, then a string containing a single quote (‘) can be escaped by using ‘\’ before the single quote. 
  
  Tips & Tricks: 
  When using the escape character function, it is important to remember that only certain characters can be used as an escape character. These characters are: \, *, +, -, ?, and !. Additionally, it is important to remember that the escape character must be defined before it can be used.
