What Are Enhancements?

• “Enhancements” is a generic term for SAP functionality that allows you to expand the SAP standard functionality

• Enhancements are called in the SAP standard code and use function modules or classes

…MOVE VBAP TO IVBAP.

CALL USER-EXIT.

IF NOT EVBAP IS INTIALIVBAP = EVBAP.

ENDIF. …

SAP standard code

…EVBAP = IVBAP.EVBAP-VKONT = ‘12345’...

What Are Enhancements? (cont.)

• Benefits of enhancementsEnhancement of standard code without modificationsEnhancements do not have to be re-implemented during upgrades or support packages

• Enhancements have to be re-tested during upgrades or support packages

• SAP constantly adds new enhancements

SAP Enhancement Type

• SAP delivers three different types of enhancementsUser exits

Oldest type of enhancementsUses function modulesTwo types of user exits:

Enhancement Dashboard

• Create a Control Dashboard for your enhancementsAdvantages:

Central repository of implemented enhancementsAllows you to centrally switch on/off enhancements Audit trail of activated/deactivated enhancements

• See article:“Create a Control Dashboard to Monitor Your Internal Controls” (FI/CO Volume 4/Issue 6)

28

Enhancement Do’s and Don’ts

• Do’s:Your enhancement needs to be performance efficient

Use “SELECT SINGLE” statements if you need to select values from SAP tables

• Don’ts:Never execute a “COMMIT” statement in an enhancement

7 Key Points to Take Home

• Enhancements are NOT modifications• Test your enhancements after each support package

and upgrade• In order to implement SAP enhancements, you need

both business and technical knowledge• Use an enhancement dashboard to centrally

maintain enhancements• Use performance-efficient ABAP code • Never execute a “COMMIT” statement in an

enhancement• Search in SAP OSS for sample codes and examples
