This takes you to the sourcing Summary page of the product that the cost sheet is created on. The source associated to the cost sheet is automatically selected in the Source menu in the product header.

The sourcing Summary page indicates whether or not the current source selected is the primary source for the product by displaying Yes or No in the Sourcing Details section. The page also indicates whether or not the current source selected is the primary source for the season selected in the Season menu by displaying Yes or No.
