In previous post I covered how to create a new spreadsheet for using with doing the edit in Excel option for the price discount agreements. The is an option on the journal header called export current price which you want to pay attention to as this will use a different spreadsheet that shows some extended price information like the current base price, current price which is the current trade agreement price. If you are editing this sheet the you will need to save back to the AOT as the PriceDiscAgreementExtended_xlsx resource. This is a quick walk through of what this option looks like.
