Invoice Holds

 11.5.10.02

Hi all

I inactivate  hold name "Tax difference" then i create an invoice matched it to a Purchase order. Then i change the tax code from what the PO was done for to a new tax code in the invoice distribution. I later validate the invoice, but i am still getting the tax variance hold.

If i inactivate this hold, why is it that the system is still holding the invoice?

Please advice, how I can prevent the system from holding invoices that i change the tax code for?
