Registering Your Own Programs, Function Modules, and BAPIs 

Use

For certain object types, SAP already provides registered standard programs in the Data Transfer Workbench.

For tasks, such as extracting data from non-SAP systems or cleaning data, you can also develop your own programs and function modules. Before you can use these for a task, you have to register them with the relevant object type.

If you want to enhance the SAP-registered BAPIs for loading data into SAP systems, you have to create and register your own BAPIs.

Prerequisites

·        You have identified SAP business object types appropriate for your legacy data.

·        You have created the programs, function modules, or BAPIs required for your data transfer project (see Developing Your Own Programs, Function Modules, and BAPIs).

Procedure

In the Data Transfer Workbench, choose Goto ® DX Program Library to get to the Data Transfer Programs Library screen.

Proceed as follows:

Choose Create registration

In the dialog box Create registration, use the F4 input help to make your selection.

·         Object type

Select one of the object types.

·         Task type and program type

Several program types are assigned to each task type. Only programs of the following program types can be registered:

Task Type	Program Type	Description
EXT	FUNC	Extracts the data from the non-SAP system using a function module.
	REPO	Extracts the data from the non-SAP system using a report.
PUR	FUNC	Cleans the data using a function module.
	REPO	Cleans the data using a report.
MAP	FUNC	Maps the data using a function module.
	REPO	Maps the data using a report.
CHK	FUNC	Checks the data using a function module.
	REPO	Checks the data using a report.
LOA	BAPI	Loads the data into the SAP system using a BAPI.
	FUNC	Loads the data into the SAP system using a function module.
	REPO	Loads the data into the SAP system using a report.
	IDOC	Loads the data into the SAP system using an inbound ALE function module.
AUD	FUNC	Checks the data in the SAP system using a function module.
	REPO	Checks the data in the SAP system using a report.
MSC	FUNC	Miscellaneous functions using a function module.
	REPO	Miscellaneous functions using a report.

 

Enter your program or function module in the Program field.

You can deregister programs that you have registered.

If it is a BAPI (only in the case of task type LOA), use the input help to choose Object type and Method in the dialog box. If available, enter the name of a program that generates test data in the Program field.

If it is an IDoc, use the input help to choose Object type and Function module in the dialog box. If available, enter the name of a program that generates test data in the Program field.

You can delete registrations. You can also assign a different method or program to a registered object type.

Result

Your programs, function module and BAPIs are now registered.
