Application Function Implementations model the specific modules, transactions, screens etc. of an Application Provider to capture at a finer grain the functionality that the Application Provider provides.

To identify an Application Function Implementation, we suggest using:

• Modules of the Application Provider defined in the Application Provider menus
  
• From the set of main links in the Application Provider homepage for web-based user interfaces
  
• Specific, named transactions or screens in the Application Provider
  
• API operation names
