Post discount for Purchase invoice

Dear Folks,

Kindly suggest me the way how to apply a discount to the posted invoice and this has to have an effect on my Item unit cost too. Ex: I have purchased some items and posted the invoice too with 1200 value and later with negotiation with the vendor it got reduced to 1000 so how should I deal with this scenario.

thanks in advance…

Hello KR,

just use Item Charge for this. It does exactly what you want to achieve!
