GL account for sales tax

 We are on version 11.5.10.2 and have recently gone to "accrue on receipt" in Oracle Purchasing.  In Payables, when invoicing sales tax on a PO invoice, the GL account for the sales tax is not coming over from Purchasing.  The account that comes up is the accural account, not the expense or capital account from the PO.  How do we bring the correct account coding into the Payables sales tax line in the invoice distributions?

Thanks
