Posting Period

Hi Experts,

Unable to import Posting date, delivery date, Document Date in PO through DTW.

E.g.: System date is 27/06/09 and posting period is set as default to the same month.

Can I import the PO which is created on 27/05/09 using DTW?

We are using SBO 2005 B and Patch is 34

Please guide me in this regard

Regards
