Use the following procedure to paste a price from any price column into the Promo Price column. For example, you can paste the price from the "Price 1" column into the "Promo Price" column.
Display the appropriate items in the grid. They can be items already in the Promotion File or not.
Click on the link "Click here to go to paste mode."
Click on the price you want to copy into the Promo Price field of a particular item. For example, you want to take "Price 1" of item 12345 and copy it into its Promo Price field. Click on the price in the Price 1 column for item 12345. Notice that as soon as you click on it, that same price copies into the Promo Price field for item 12345.
Repeat step 4 for any other items.
Click Change to save your changes.
The night before the promotion begins, activate the promotion prices by running the Update Promotion Price Report (RUP) with option F. Typically this report is run as part of an end-of-day queue.
