If a superseded product code is chosen when using a Pricebook in a transaction, a dialogue box will appear. This dialogue box alerts you to the supersession of the product code.

This shows the product code that has superseded the old product code. Select the line to use the superseding code showing in the Superseded by drop-down. As many or as few lines can be selected to use the superseding code and then select Use Superseded Code. 

This will update the product codes on the transaction to use the superseding product code on the relevant line. Any superseded products that aren’t selected will use the existing product code on the transaction.

 Additionally products that the supplier has superseded and marked as superseded in the Pricebook, will also generate this message when trying to select the superseded products in the tramsaction.
