8. Motivation
Main benefits for reduced custom code objects
27.06.2015 Custom Code Management Tools Seite 8
• Less maintenance and adjustment efforts for custom code

9. Getting started
How do I manage my custom code?
27.06.2015 Custom Code Management Tools Seite 9
STEP 1 Analyse custom code in system(s) based on actual usage:
Most usage in the system? 
Usage, but not core business 
Not used 
STEP 2 Identify the pain points in - fix them
Security
Performance
Maintenance
should be decommissioned
If the budget allows it; clean up
UPL
CCAPPS / ATC

13. Usage & Procedure Logging
Display UPL Data
02.07.2015 Seite 13
• Find code that is used most
• Identification of code that is not used with manual work -
• Find used EXITS and Enhancements
• Use UPL List for ATC object sets
• Currently no user segmentation like provided by SCOV

What is the most complex code in one section?
27.06.2015 Custom Code Management Tools Seite 22
• Analyses the code for static metrics
• List all SAP modifications
• ( incl. Exit - coding )
• Limitations:
• No detection of complexity across modularisation units

23. SAP Code Metric Tool
Identification
27.06.2015 Custom Code Management Tools Seite 23
Lines of coe / number of statemts - what is the biggest codings?
Complexity ( conditions / decisions ) - where is the “spaghettiest” code?
Database interaction - who is reading / writing DB?
Autors / Version / Changes - which code was fixed most?
…

Identification
27.06.2015 Custom Code Management Tools Seite 25

26. SAP Code Metric Tool
Alternative : Code Inspector Metrics
27.06.2015 Custom Code Management Tools Seite 26
Metrics: Max nesting, long coding block, comments, others
• Less Information available compared to Code Metric Tool
• Not so handy in use
• Can be used to create tends charts if executed regularly (Excel)

27. ABAP Test Cockpit
Use ATC to analyse trends based on statistic
27.06.2015 Custom Code Management Tools Seite 27
• Schedule ATC periodic runs to monitor trends in the coding
• Use stable check variant
• Combine Information with Code Inspector Metrics (Nos / Loc )
• ATC messages per number of statements; lower is better

28. ABAP Test Cockpit
Use ATC to analyse trends based on statistic
27.06.2015 Custom Code Management Tools Seite 28

30. SQL Performance Tuning Worklist
Where do we waste performance?
27.06.2015 Custom Code Management Tools Seite 30
1. Start SQL Monitor on productive system
2. Merge with Coverage Analyser data from test system
3. Merge with ATC findings from development system
4. Inspect results in development system SWLT
What Code is working on which tables hard
and has ATC Issues?
