We have found several postings made in October which were posted into P7, P8 and P9 when completing our P10 accounts. All of these prior periods were set as "On Hold". The transactions were all supplier invoice transactions.
We tested this again today once we found the issue. If we do a General Journal, D365 rightly blocks it by saying the prior period is "not open"
However, if we post a supplier invoice, no issue, it lets us post to an "On Hold" period, and can see the values in the closed periods TB.
I've heard about feature management, have checked the settings, nothing there that will stops period validation when posting supplier invoices.
D365 FO version 10.0.27
Any thoughts, suggestions ...
