Function modules are procedural blocks stored centrally in the global Function Library of the SAP system. Every function module belongs to a function group. A function group groups function modules that are related in functions or process the same data.
Components of Function Group
- Data Objects – global to all function modules within the function group. Function modules within the group can access as well as change function group data objects
- Subroutines – can be called from all function modules in the group
- Screens – can be called from all function modules in the group
