Objectives

At the end of this presentation, you will know:

• Different SAP Enhancement Techniques• When to Apply the Technique• Which Technique to Apply


Topics

• BDT• FQEVENTS• Field Exits• User Exits• BADI• Modification Assistant• Enhancement Spots• BTE• Append Structure


BDT

BDT stands for Business Data Toolset• BDT is a central control tool for maintaining SAP dialog

programs.

• It is used at SAP for maintaining application transaction. • SAP extended this tool for use by development partners and

customers. • BDT is used to:

• add new custom fields • hide standard fields • move standard fields from one screen to another • add new menu options • add custom validations all without modifying the underlying transaction

Please Note: A transaction must be BDT enabled!


FQEVENTS

Transaction FQEVENTS is meant to maintain FI-CA events and some specific events which are used by the mass activities.

• To use FQEVENTS, you need to:

• find out events for the transaction • check the documentation for the function modules available

Please Note: Function modules can only be used for enhancement!


Field Exits

A field exit is an old enhancement technology linked to a screen input field.

• Field exit can be used to:• change the value of the field

• trigger an error message on that field • A field exit applies to a given data element and a given dynpro

or all dynpros, and is active for all clients.• It is called just after the user has pressed a key.• It calls a function module with a special name that needs to be

registered via program RSMODPRF.

• The enhancement technique (Open FI) that was developed for Financial Accounting component.

• The Open FI assumes that enhancement will only take place on three levels (SAP – partners – customers)
