Custom Code Management

The innovative concept of Custom Code Management from SAP provides comprehensive insight on

how companies can efficiently and effectively manage their home grown Custom Code. From

conception to retirement, it delivers transparency on Custom Code objects, automates the analysis of

every change and clearly identifies their usage, utilization and business impact of the customer objects.

It also supports optimization cycles with a project based approach to reduce the Custom Code footprint.

Innovation on Top of Stability Enhancement Packages reduce conflict between stability and innovation

INNOVATION

STABILITY

Stable and robust business

processes for maximum efficiency

and low TCO

Routine deployment of support

packages to sustain compliance

Fast and easy introduction

of business innovation at

any time when needed

ENHANCEMENT PACKAGES =

INNOVATION + STABILITY

• Enable IT to continuously provide new

functionality: Installation of enhancement

packages as part of routine maintenance

• Selective, non-disruptive activation of

innovation at any time - driven by

business needs


Customer individual requirements Completion of functionality

Customer Driven Innovation

Standard versus Customization

Enhanced by Custom Code

T Having Custom Code is “ok” – as long as it is based on an educated decision “

T Doing it “right” helps to minimize the incremental effort to develop and operate your code “ Implications regarding the loss in “built-in” capabilities need to be properly addressed “


SAP Standard Software Enhanced by Custom Code Competitive Business Benefit versus Operational Effort & Risk

And ... Custom Code increases the “Long tail” efforts of your solution

Increase of overall TCO

Higher maintenance and corrections efforts for unknown amount of custom code

Increased potential risk of daily operation

Figures from typical customer systems*

8000 objects in the customer namespace and 1500 modifications or enhancements

65% of them have not been used within the last 4 weeks

up-to 15% are identical or very similar to each other(Clones)

some more became obsolete through recent SAP standard functionality

30-50% of them need to be adjusted on the occasion of a SAP standard upgrade

20% of the system resources are attributed to the execution of custom code

Code inspection returns several hundred severe messages per development package

These inefficiencies alone can equate to an overspend on system support of between

€250,000 - €2 million per annum depending upon the size of the SAP system and extent of custom

code.

Creating and Managing Custom Code adds to your Bill.

How much? That is not entirely clear. We can reduce it Today! “

custom code?

Which business processes are currently in

use?

How can I better take advantage of the

current capabilities?

How can I ensure the support?

How can I consolidate or standardize my

business processes?

!

Missing information about mission critical business processes

and use of custom code is a top issue “

This is essential for an efficient and successful management process! “



Optimization with Custom Code Management

Analysis of custom code situation is fact based (holistic approach, anamnesis).

The ‘Single source of Truth’ is established .

Optimization follows the minimal-maximal principle.

Lowering the TCO by selection of the right optimizations.

Sustainable optimization along the life cycle.

Optimizes existing custom code environments.

The Library as monitoring tool to determine custom code healthy level.

Close the loop between proactive and reactive optimization.

Generate city model after optimization

Optimizations Regular data
