When creating feeds the Product Mash automatically assigns the the Actinic fields to the correct feed values. You can override this or use more than 1 Actinic field for 1 feed value.
To use 2 Actinic product fields in 1 feed value use the following approach:
Create a property with the name that you want to include the extra information for and assign the value macros to that field. For example, to add the manufacturer to the description field in Googlebase you should create a property called description and assign a value of !!SectionTitle!! - !!Description!! to it. This assumes that you have already defined the manufacturer as the section title. This is shown below:
You can use most of the Actinic product information by using other macros. For more information on these use the following link:
