Statistical Account Journal does have the option to add Document No, but there is No Series in the Batch Setup.

If the user is using a No Series that could also be used in a different documents postings, this could lead to duplicate No Series for both Statistical Account Ledger Entries and the other document.

If No Series is added to the batch, this should block the user from posting duplicate No Series from the same No Series if it's used in different postings.
