Business Transaction Events 

Definition

The business transaction event is an event for which an SAP program extends the system without modification, depending on the settings in Customizing.

Use

You use events to add individual functions to BCA. Events enable these additional functions without affecting the SAP programming.

At the defined event, data is transferred by the system by means of an interface to the function module. This can also pass data back to BCA in accordance with a predefined interface.

You can connect three types of additional components at every event:

·        SAP components

·        Function modules from software partners

·        Function modules developed by the customer

Example

Before you save a new account master record, the system offers you the Determine General Ledger Group event. At this event you can call up a separately developed function module that determines the general ledger group (for example, an industry) from business partner data. Data transferred by means of the interface is entered in the appropriate field on the account.

Structure

SAP provides sample function modules (called SAMPLES) for each event, which describe the interface and can be used as a template for modules to be developed. To use a SAMPLE, copy it into your namespace and finish programming it.

Integration

P/S modules can be provided either by an SAP standard application, by an external software company, or you can create them yourself. You activate or deactivate each function module in the Implementation Guide (IMG) for Bank Customer Accounts (BCA).
