Business add-ins (BADIs) are predefined user exits. They enable businesses, partners, and customers to add additional softward to the SAP source code. The linkup of SAP's New Dimension Products, such as APO and BW, to the standard system is thus possible.
Customer-specific functions can be executed before the save time and after the database update.
The following methods are available for the BADI with the definition name 'BADI_LE_SHIPMENT':
AT_SAVE: BADI is called up at the time of the save. Checks and return to dialog are possible.
BEFORE:_UPDATE: BADI is called up right before the data is saved to the database, that is, when all the data is available (for example, internal ly assigned shipment number).
IN_UPDATE: BADI is called up after the database update.
Creating a BADI method:
Call up transaction SE19. Enter a name of your choice. Choose "create" and in the dialog box enter the definition name 'BADI_LE_SHIPMENT'. Afterwards, enter a short text for implementation. Save the BADI.
On the tab page 'Interface', choose the method for implementation by double-clicking on it. Now you can enter your customer-specific program code. Save and activate the code. You can acess the transmission parameters entered in the BADI definition. With the method ***_AT_SAVE you can initiate the exception ERROR_WITH_MESSAGE (description 'An error message has occurred' ) if you wish to return to the dialog.
Afterwards, go to the heading and activate the interface.
