Overview of Number Assignment in RAP

• Number assignment: setting key values for entities during Create
• Essential for identification and data consistency
• Various methods for key generation available

Late Numbering

• Key is assigned only during Save
• Suitable for number ranges or sequential numbering
• Supports gap-free and controlled assignment
• Implemented via adjust_numbers method in the Behavior Handler

Behavior Definition Configuration

• Early internal numbering (Managed):

field ( readonly )
field ( numbering : managed ) <KeyField>;  

• Unmanaged early/late numbering:

early numbering // for early numbering
late numbering  // for late numbering
field ( readonly ) <KeyField>;  

• Implementation of methods FOR NUMBERING and adjust_numbers required

Recommendations

• For GUID keys: use Managed early numbering
• For sequential numbers with gap-free sequence: use Late numbering
• Use Unmanaged numbering when custom logic is needed
• Configure Behavior Definition properly and implement methods
