  Key Concepts: 
  LET expression is a type of expression used in the ABAP Runtime Environment of SAP. It is used to assign values to variables and can be used in combination with other expressions. It is composed of two parts: the target variable and the source expression. The target variable is the variable that will receive the value from the source expression. 
  
  How to use it: 
  To use a LET expression, you must first declare the target variable. This can be done using the DATA statement. Then, you must specify the source expression, which can be any valid ABAP expression. Finally, you must use the LET keyword to assign the value of the source expression to the target variable. 
  
  Tips & Tricks: 
  When using a LET expression, it is important to remember that the target variable must be declared before it can be used. Additionally, it is important to note that LET expressions are evaluated from left to right, so any variables used in the source expression must be declared before they are used.
