Billing document in FI - different document and posting date

Hello dear coleeges,

I have a requirement that the document and posting date are different in the FI document after billing invoice is posted.

E.g.Group period closes on 02.09.2011 but local period closes on 31.08.2011

So we need that the FI document date is 31.08.2011 to suit local reporting needs but the posting date is 03.09.2011 to suit group closing.

I know that system takes the billing date for both doc and posting dates, but is it possible that these dates are different?

Is it possible to achieve this in a different way?

Thanks
