Yes, you put multiple tax authorities into a group.

We have a vendor who we sometime gets charges HST and other GST. We already have tax group GST, NOTAXU and HST. However, when we enter a PO, we need to be able to select either GST, NOTAXU or HST, but it won't allow us to change it. Even at the PO Invoice Entry, the tax group cannot be change. At the Vendor set up level, I am only allow to put one tax group....Can you help?

Change the tax group when you enter the PO.

Thank you so much! I worked!

you need to change the tax on the the PO BEFORE you enter any items.  once an item has been entered, the tax table is locked.  if you screw up, then you need to delete the items off, hit POST then go back into it to change the taxes then re-enter the items.  if you have used an requisition then all bets are off and you need to make a new PO.

Another solution to be done if this is a rampant problem is to just create 2 different vendor codes that have their assigned taxes setup.  All depends on how detailed the purchasers can be.

Thanks Mike. So, once it is received, at the PO Invoice Entry, I cannot change the tax neither, is this correct?

correct.  you can change the amounts and the tax "CLASS", but you cannot change the tax GROUP once an item has been entered onto the PO and any step down the line from that point.

Thanks!
