You can define all or part of the binding editor by entering a function module in the binding editor.

A programmed binding is available to perform complex assignments. Examples of this are:

• You would like to perform calculations or checks on the container elements before assignment.
• You want to combine two or more container elements in any before assignment.

To execute the binding, the system calls a function module, to which the two relevant containers are passed as table parameters. This function module is programmed specifically for this binding and is entered in the definition of the programmed binding.

You can use both a programmed binding that uses the BOR container and a container interface. The function modules used must support each interface needed.

Define a corresponding function module. To do this, you either choose an existing function module from the list or have the system create a function module for you by choosing . This function module that is created by the system is based on the following function module depending on the container used.

The function module documentation contains all the necessary entries for the interface and notes on programming.

You should create function modules for the programmed binding in the function group specified in the basic data of the workflow. This function group should contain all the objects created for this workflow.
