Function groups are nothing but special ABAP programs. Function modules form part of function groups in ABAP programming. Function modules are special procedures which have a global view and can be called from other ABAP programs. Function modules can only be implemented in special ABAP programs, such special ABAP programs are called function groups. To make it clear, function groups are not programs that can be executed using transaction codes or by entering the name of a program. Function groups should be looked upon as framework programs for function modules.

Function groups normally consist of the following:
- Data declarations i.e. global data objects
- Subroutines
- Screens

As pointed out earlier, function groups consists of a framework program and a number of 'include' programs. The framework program and include programs are automatically created once a function group is created. The include programs can be easily created using the forward navigation in the ABAP workbench. A function group can be created using the transaction code SE80. The steps for creating a function group in SAP ABAP programming are given below:

Step 1 - In transaction code SE80, the user should select object list for function group.

Step 2 - Enter the name of the new function group example ZEF130_TEST

Step 3 - Next click on 'Create Object' which comes as a popup window

Step 4 - Confirm 'Yes' Insert Function Group

Step 5 - Once a function group is created, function modules can be created in the submenus.
