Tax Code removed on changing the posting Date in Purchase Order

Question

Dear All,
This is with reference to the Purchase Order Document tax part, the document has been defined with the approval procedure and document series followed as annual series. The document series is linked to the period indicator as I am using the monthly series for the A/R & A/P Invoice.
Now some Purchase Order was generated in the last month i.e. 30 NOV 07 which has gone for approval. These document are approved in the current month (Dec 07) & user are trying to add the records it displays the message as "Date deviates from permissible range [Purchase Order - Posting Date]  [Message 173-11]" as the period indicator is changed to Dec 07 in document numbering.
The problem is when user changes the document date to Dec 07 for posting; system removes the tax codes, which is available in the document. Now as this is approved document user is not able to change or renter the tax codes.
In this situation what can be done as the same case will again happen for the next month.
Pls. provide the solution / work around for this problem.

hi yogesh,
Cancel/Close the created purchase order.
First you should change docduedate in posting period upto december 2007/end of fiscal year,by following the below path.
(Administration->sytem intialization-> general settings--> posting period tab)
Create a new purchase order.
Send it for approval,authorizer can change date as required,
once the posting date changes,tax code get refreshed,authorizer
need to select tax code once again.
<b>Tax code normally get refreshed when you change posting date it's normal
system behaviour.</b>
After authorizer does above changes,he can approve purchase order.
Once purchase order is approved,orginator can add it as purchase order in draft stauts.
<b>After approval we can not do any changes in purchase order.</b>
Hope my solution will solve the problem.
Thanks,
With regards,
