Enhancement Without Modification of the Object Links (SAP Library

Enhancement Without Modification of the Object Links

Use

In R/3, a large number of object links are provided to documents such as materials, equipment, and production resources/tools. You can find the complete list of SAP objects in Customizing for Document Management, under Control Data ® Maintain Screen for Object Link. In this activity you can also enter your own object links.

The Business Add-In (BAdI) is defined so that you can integrate your own objects in transactions for document management (CV01N, CV02N, CV03N, CV04N) without modification.

Note

You must integrate the object link from the object using the APIs of the function group CV140. SAP objects need to be modified.

Integration

The interface for this BAdI is defined in R/3, and the call for the implementation is programmed into the application programs for document processing.

Subscreens for Dialog Processing

Your call your subscreen from subscreen container 1500 in the document management program.
To do this, you create a program that calls the subscreen. Then you need to make the implementation.

Implementation of the Business Add-In

The Implementation includes information about the program that contains the subscreen that you want to call. For example, you create in implementation a subscreen for document processing and document search.

Prerequisites

In order to create the customer program in the Screen Painter, as well as to create the implementation, you need to be able to use the ABAP programming language.

You need to do the following in Customizing for Document Management:

Maintain Screen for Object Link
Enter screen number 500 for subscreen container 1500.
In this case, the application program copies the flow logic for screen container 1500.
These settings are made in Control Data ® Maintain Screen for Object Link.

Maintain Key Fields
Enter the object. You do not need to make any other settings (such as transaction code).

Define Object Links for Document Type
Create an entry for the document type that you want to link with the new SAP object.
You make these settings under Control Data ® Define Document Types ® Maintain Object Link Descriptions and Define Object Links.

Features

With this Business Add-In, you can edit the dialog processing for the new object links by using the following transactions.

Edit Document	Find Document
Create document Transaction CV01N	Find document using object links (transaction CV04N)
Change document Transaction CV02N
Display document Transaction CV03N

Activities

You need to do the following for new object links:

You need a subscreen to maintain link data. Create separate subscreens in your program for both document processing and the search function. These subscreens must each contain a table control for the object link data.

You program the complete flow logic for the new subscreen in Screen Painter (transaction SE51). You program the screen layout in PROCESS BEFORE OUTPUT (PBO), and the screen processing in PROCESS AFTER INPUT (PAI).

You can find information on creating the program under:
Screen Containers and Customer-Specific Subscreens.

Implement the program to process the subscreen with reference to BAdI definition DOCUMENT_OBJ. Use the following function: Tools ® ABAP Workbench ® Utilities ® Business Add-Ins ® Implementation (Transaction SE19).

You can find information on BAdI implementation under: Implementation Interface.
