  A function pool is a collection of related functions in the SAP system. It is used to store and manage functions that are used in the development of programs.

  Function pools are used in the development of programs in the SAP system. They are accessed through the Workbench Tools, such as Editors, Painters, and Modelers. To access a function pool, you must first select the module that contains the desired functions. Once you have selected the module, you can then select the specific function from the list of available functions. 
  
  Tips & Tricks: 
  When using function pools, it is important to remember that each module contains a set of related functions. This means that if you need to access a specific function, you should first select the module that contains it before selecting the specific function. Additionally, it is important to remember that some modules may contain multiple versions of a particular function, so it is important to select the correct version for your program.
