Yes, you should be able to enter batches for November without effecting already posted transactions for October - just don't post them if you don't want them included in the month end reports (i.e. GL Transactions report).

Keep Novembers' transactions in separate batches though.

If you are entering transactions for November batches, just use today's date (i.e. November) - you won't have to change it then unless you are entering time for other dates.

If you are going to be entering October transactions, then it is best to 'sign in' to Adagio Time&Billing using the October date - then you won't have to remember to change the date in the entry details screens. Once all October entries are entered and posted and all month or period end procedures, reports etc are completed, you can then post November's transactions as normal.

This is typical procedure really, for any Adagio modules.

Take care,
