diff btw BAPI AND CALL TRANSACTION and fn module

[Former Member]

Hai can anybody tell me what is the difference between BAPI and CALL TRANSACTION?

BAPI and BDC?

Diff between function module and BAPI function module?

Hello,

The CALL TRANSACTION is a simulation of a SAP transaction.

It calls screens and uses fields of this screen.

BAPI is a function module simulating a SAP transaction but without screen but with all controls.

Function Module is included in BAPI and realizes a fucntionnality of a transaction. (control, compute, ... )

Hi Balu,

A BAPI is faster because it is updating the DB "directly" through ABAP code.

A BDC with call transaction goes through the whole screen sequence like any user would do, simply put, it is filling screens.

Major difference is that a BAPI call is not screen dependent, so when the screen sequence changes, it does not effect when using BAPIs.

BAPIs are function modules that are well documented and are RFC enabled. THey also usually perform some specificy business action, such as "Create Purchase ORder".
