System Elements Reference
Overview
This quick reference lists common calendar-sensitive system elements used in formulas and rules.
Core Calendar And Segmentation Elements
| System element | Meaning | Typical use |
|---|---|---|
PRD BGN DT | Period begin date | Determine start-of-period logic |
PRD END DT | Period end date | Determine end-of-period logic |
PAY DT | Payment date | Payment-date-driven taxation or reporting |
SEG BEGIN DT | Segment begin date | Segmented proration and slicing |
SEG END DT | Segment end date | Segment close logic |
CAL RUN ID | Current calendar context | Trace and context-sensitive logic |
FREQUENCY | Processing frequency context | Conditional logic by cycle type |
How To Use Them Well
- prefer system elements over hard-coded dates in formulas
- test segmentation formulas with actual mid-period changes
- validate the calendar or segment context before blaming a formula
Typical Patterns
| Scenario | System elements usually involved |
|---|---|
| accumulator based-on checks | PRD BGN DT, PRD END DT, PAY DT |
| proration or slicing | SEG BEGIN DT, SEG END DT |
| calendar-aware eligibility | FREQUENCY, CAL RUN ID, date elements |
Key Takeaways
- System elements let formulas stay generic and calendar-aware.
- Segment-aware formulas are only reliable if they actively consume segment system elements.
- This reference is most useful when read alongside the supporting-element and segmentation pages.
