  Key Concepts: 
  A static variable is a type of variable in SAP ABAP that is declared with the STATICS keyword. It is a global variable that can be accessed from any program within the same ABAP runtime environment. It is used to store values that are needed across multiple programs and can be used to pass data between programs. 
  
  How to use it: 
  Static variables are declared in the top-most include of a program and can be accessed from any program within the same ABAP runtime environment. To declare a static variable, use the STATICS keyword followed by the data type and name of the variable. For example, to declare a static variable called “my_var” of type string, use the following syntax: STATICS string my_var. 
  
  Tips & Tricks: 
  When declaring static variables, it is important to ensure that they are declared in the top-most include of a program. This will ensure that they are accessible from any program within the same ABAP runtime environment. Additionally, it is important to ensure that all programs accessing the static variable use the same data type for the variable.
