Calendar Policy
The Calendar Policy page controls the fiscal posting model for a service or business-unit family. It affects both accounting period generation and how long closed periods remain postable.
Navigation: Administration → Financial Setup → Calendar Policy
What Is a Calendar Policy?
For accounting, a calendar policy determines:
- Year Start Month — where the fiscal year begins
- Adjustment Period Count — how many special adjustment periods are created
- Default Posting Lag Days — grace days for late posting into the immediately preceding closed normal period
- Max Open Periods — how many normal periods may stay open at the same time
- Require Sequential Close — whether periods must close in order
- Year-End Close Method — manual or automatic year-end close behaviour
Key Effects on GL Posting
Calendar policy shapes the posting engine in these ways:
- It defines how many periods can be open together
- It defines the lag window for late posting into a just-closed period
- It controls whether adjustment periods exist
- It affects the fiscal period states created per business unit
- It indirectly affects backdated and future-dated posting decisions
Posting Lag Days
If posting lag days is 5, a later normal period may be open while the immediately previous closed normal period remains postable for only five additional days.
The selected journal date still remains the actual date the user chose inside that closed period.
Adjustment Period Count
If adjustment periods are configured, the system creates special fiscal periods used for controlled post-close correction activity.
Max Open Periods
This controls how many normal periods can remain OPEN at once for a business unit. It matters for back-office posting because a selected date may still be postable if its normal period is still one of the currently open periods.
