Automating Posting Periods in Business Central with Date Formulas

Hi Reader,

In this series, we will talk about all new features in Business Central 2026 release Wave 1.

Sorry for delay, I was busy with personal family stuff. But I can guarantee that we will cover each and every feature.

If you want to discuss something discussed first, please specify in comments. 

Introduction

Managing posting restrictions in Business Central often meant manually updating fixed dates. With the new date formulas, posting windows adjust automatically based on today’s date — saving time and reducing errors.

1. What Are Date Formulas?

Date formulas are dynamic expressions that calculate allowed posting ranges relative to today’s date. Think of them as “smart boundaries” that move with time.

2. Where to Use Them

  • General Ledger Setup

  • User Setup

  • General Journal Templates

3. Examples in Action

  • Current month only: <-CM> to <CM> → Mar 1–31

  • Rolling 30 days: <-30D> to <0D> → Feb 15–Mar 17

  • One month back, one week forward: <-1M> to <1W> → Feb 17–Mar 24

  • Previous month close: <-1M-CM> to <-CM-1D> → Feb 1–Feb 28

  • Today only: <0D> to <0D> → Mar 17

4. Priority of Checks

Posting restrictions are validated in this order:

  1. User Setup

  2. General Ledger Setup

  3. General Journal Template (if mandatory toggle enabled)

5. Mixing Formulas & Fixed Dates You can combine formulas with fixed dates — one boundary can be dynamic, the other fixed.

Conclusion Date formulas make posting period management smarter and more efficient. By adopting them, you ensure accuracy, reduce manual updates, and keep your financial processes error‑free.

MSDYN365BC - Data Upgrade To Microsoft Dynamics 365 Business Central on premises.

Hi Readers, We have already talked about the number of steps for upgrading to Business Central on Premises from different NAV versions. After that article, I received multiple requests for an article which list down steps for Data Migration. In this article, we will discuss steps of data migration to MSDYN365BC (on-Prem) from NAV 2017. For this article, I am considering a Cronus Demo Database without any customization. For an actual upgrade project, we will have to complete object merge using compare and Merge process. After the Merge Process, the next step is data migration. Let's discuss those steps. Direct Upgrade to Microsoft Dynamics 365 Business Central (on-Prem) is from following versions - 1. NAV 2015. 2. NAV 2016. 3. NAV 2017. 4. NAV 2018.
