Unposted Journals - Will they affect year end? (eBS R12)

Hi,

We have some unposted journals in our November period, which were created in error. The system does not let us delete these journals, so we've just left them there in an unposted state.

November was then closed, to do December's period end, and so forth

However, now we need to do year end. What I wanted to check was, will these unposted journals sitting in November affect our year end? Or is it fine to just leave them there unposted.

Note: Our accounting convention is Accrual with Encumbrance Accounting

Thanks
