ABAP Programming in BW

Purpose

The purpose of this document is to outline and define concepts and strategies that

constitute best practices regarding the use of ABAP programming in BW.

It is strongly suggested that all staff (both senior and new hires) follow this

document closely.

Objective

Obecti!e of this document is to de!elop programming process guidelines andde!elopment standards considering the possibilities e"ist for using ABAP to

customi#e the BW en!ironment to transform the data as re$uirements dictate% as

well as pro!ide additional processing during e"traction and updates.

Scope

ABAP Programming Scope in BW and R/3 etractors

Tec!nical Area "escription

B# $ser #it Allows the creation and population of !ariables andcalculations for &ey figures and !ariables on a runtime basis.

This user e"it is called each time B'" is e"ecuted.

R/3 $ser #it This user e"it is found in * under +,O- and contains

additional programming that is needed to fill field additions toe"tract structures. We can also create additional business

logic against data prior to its transfer to BW.

BW TransformationRoutines

Transformation routines are part of transformation ruleswhich are in!o&ed as data is transferred from * to BW-ata targets% or from within BW from one infopro!ider to

another. Transformation rules are each infoobect specific.

BW Start Routines tart routines in BW Transformations are used to manage

whole subsets of source data before Transformation rules aretriggered.

BW #nd Routines 'nd routines in BW Transformations are used to manage wholesubsets of resulting data from tart routine and

Transformation ules.

BW #pert Routines '"pert outine is a new feature in BI /.0 which enables user

can define e"actly how the Transformation wor&s. '"pertroutines are used only in special scenarios. When an e"pert

routine is created then all transformations rules along with

start and end routines will get deleted. ome times e"ert

routines impro!es the performance of data load e!en further.

BW "TP Routines -TP outines are used to do some filtering and calculations on

the selection screen fields depending on the business

re$uirement.

Routines

Infopac&age le!el routines are used to in scenarios li&e if

source system need to be selected dynamically% selecting file

name dynamilcally and filtering data coming from source flat

file.

Common %mplementation scenarios of ABAP Programming in BW

1or BI /.0% in data staging% there are many aspects that we can write abap

code to deal with data.

'( %nfoPac&age Routine

The infopac&age routine gi!en below is an e"ample to create dynamic file name.

ABAP Programming in BW

This type of routine is only intended for use in special cases. 5ou can use the e"pert routine

if there are not sufficient functions to perform a transformation. The e"pert routineshould be used as an interim solution until the necessary functions are a!ailable in the

standard routine.

While writing routines% in order to dramatically impro!e performance% the following stepsshould be ta&en2

6se Internal Tables of ,aster -ata (instead of direct read of physical P3Tables)
