how do we do a credit for a price adjustment, and we’re not returning items to vendor? - I am thinking of Transaction > Payable > enter Vendor Credit. is it correct or it has to be done a different way?

If you do that, the Vendor Credit will not be linked to the Vendor Bill. If you know the related Vendor Bill, you can view it then click the Credit button. Ensure that you are not using the inventory items in the Bill Credit, so as not to decrease the inventory on hand. You can use a non-inventory or other charge item instead.

yeah didn't think about linking Perfect thanks!!

Believe you can set the QTY to zero as well, if you want to use that inv. item sku. (or this entirely throws an error when you submit.... i honestly forget)

Oh you mean 0 quantity then force the Amount column? I'll try this 'cause it's nice to link the credits back to the actual inventory item itself.

correct.
