Our client raised a bug where they set Bank module access to for a particular calendar month expecting that it will prevent users from posting/reconciling or performing other actions in the Bank ledger during the Period-end process. The client was surprised to learn that users were able to carry on performing their day to day tasks despite Bank module being closed.

We tied to find any official documentation, which would specify restricted activities when each sub-ledger access is set to None, but there was nothing available.

When we raised a ticket with Microsoft and were told the following "When status is set to It only blocks posting to GL during bank reconciliation. Bank reconciliation will not post any voucher to GL if there is no adjustment or new transaction".

The above explanation from Microsoft indicates that the remit of the Ledger calendars module access functionality is very limited and to some extent counter intuitive, because users would at least expect to be prevented from posting payments(AR/AP) to bank ledger when the Bank module access is set to None.

After discovering that setting Bank module access to did not prevent them from doing their daily activities, our Client started to feel nervous about using the Ledger calendars to restrict access to sub-ledgers during Period end, because they were not sure what restrictions users would have.

Microsoft need to provide documentation where they will details what activities and transactions are restricted when each sub-ledger access is set to None.
