You can now use date formulas to control the range of allowed posting dates in General Ledger Setup, User Setup, and General Journal Templates. Instead of entering fixed dates that you must update manually every period, you enter a date formula and Business Central calculates the allowed posting window based on today's date.

Where you use date formulas

The new Allow Posting From Date Formula and Allow Posting To Date Formula fields are available on:

General Ledger Setup (Though you might need to choose Show more to view them.)
User Setup
General Journal Templates

How posting date formulas work

Business Central evaluates your date formula against today's date each time a posting date is validated. The table below illustrates various usage examples:

Scenario	Allow Posting From Date Formula	Allow Posting To Date Formula	Today's Date	Resulting Range
Current month only	`<-CM>`	`<CM>`	Mar 17, 2026	Mar 1 – Mar 31
Rolling 30-day window	`<-30D>`	`<0D>`	Mar 17, 2026	Feb 15 – Mar 17
One month back, one week forward	`<-1M>`	`<1W>`	Mar 17, 2026	Feb 17 – Mar 24
Previous month close	`<-1M-CM>`	`<-CM-1D>`	Mar 17, 2026	Feb 1 – Feb 28
Today only	`<0D>`	`<0D>`	Mar 17, 2026	Mar 17 – Mar 17

Priority of posting date checks

Business Central evaluates posting date restrictions in this order:

User Setup
General Ledger Setup
General Journal Template (when the Journal Templ. Name Mandatory toggle is enabled on the General Posting Setup page).

Using formulas together with fixed dates

For each boundary (From or To), you can choose either a fixed date or a date formula. When you enter a formula, the corresponding fixed date is cleared. When you enter a fixed date, the formula field is cleared. You can mix a fixed date for one boundary and a formula for the other.
