Integrate Function Modules / BAPIs

This page shows how to use the Function module / BAPI integration type.
The Function module / BAPI integration type can be used to parameterize and execute SAP function modules and BAPIs for automation.

About Function Modules / BAPIs

Function modules are procedures that encapsulate and reuse global functions in the SAP system. SAP systems contain several predefined functions modules that can be called from any ABAP program. A Business Application Programming Interface (BAPI) is a remote function module that can access business data and processes of an SAP system from different systems.

Prerequisites

• A connection to an SAP system is available, see SAP Connection.
• The SAP user has sufficient user rights, see SAP Authority Objects.

Look up a Function Module / BAPI

1. Create a new service of integration type Function module / BAPI.
2. In the Search SAP function modules menu, enter the name of a Function Module / BAPI or a function groups . Use wildcards (*) if needed.
   
3. Click [Search] to display the search results.
4. Select a source file from the list of available search results .

The settings of the Function module / BAPI integration type open.

Define the Function module / BAPI Service

Set up parameters for the service. The necessary parameters of a Function module / BAPI service vary depending on the BAPI.

1. Add input parameters (data you want to send to SAP) to the service, see Import Parameters.
2. Add output parameters (data you want to receive from SAP) to the service, see Export Parameters.
   
3. Click [Run] to check the results, see Running Services in yunIO.

Parameterize the Service

Import parameters can be parameterized in the request body of the service. The depicted example shows the request body of a service where the Import Parameter NAME is set to Supplied by Caller.

Custom BAPIs

The use of custom BAPIs (Z function modules) is possible. Issues specific to Z function modules are not included in the scope of support provided by Theobald Software.
