Dynamics 365 Business Central: How to quickly check whether the posting date is valid in AL (Within the allowed posting date range)

Dynamics 365 Business Central

The article titled "Hi, Readers" provides a mini tip about Business Central, specifically on how to quickly check whether the posting date is valid in AL.
The posting date in Business Central indicates when a document was registered and is important for recording and reporting financial transactions based on the date they occurred.
Posting periods can be used to specify when users can post to the general ledger, and these periods can be defined on the General Ledger Setup page by entering dates in the Allow Posting From and Allow Posting To fields.
Different posting periods can be defined for specific users on the User Setup page to allow for exceptions and override the periods specified on the General Ledger Setup page.
If the posting date is not within the allowed range, an error message will be prompted during posting, stating "Posting Date is not within your range of allowed posting dates."
To automate the process of checking if the posting date is valid in customizations, the CheckAllowedPostingDate method in codeunit 5700 "User Setup Management" can be used.
Alternatively, the IsPostingDateValid method can be called directly, but the error message will need to be written manually.
The article provides a simple example of adding an action on the Sales Order to check if the posting date is valid, with a test video provided on YouTube.
