Alternative Binding Definition (SAP Library

Alternative Binding Definition

Use

As an alternative to describing a binding in the binding editor, you can define a binding by specifying a function module.

This type of binding definition is particularly useful as an alternative to the line-oriented binding definition described up to now, if:

You work on both sides of the binding definition with structure references and the binding editor does not enable the desired assignments
You want to perform calculations or checks on the container elements before assignment
You want to combine two or more container elements in some way before assignment

Features

To execute the binding, the system calls a function module, to which the two containers are passed as table parameters. This function module is programmed especially for this binding and is entered when the alternative binding is defined.

The binding definition based on container elements is deleted.

Activities

You define an appropriate function module for each binding direction. The interface for these function modules is defined. Use the function module SWA_TEMPLATE_EXECUTE_DATAFLOW as a template. The function module documentation contains all the required information on the interface and programming.

To enter the function modules, you choose Alternative binding in the binding editor context menu and make the entries in the relevant input field.
