Header Items sum individual serialized items together in a generic item record. To use the Header Item feature, you need to add an item as normal with all of the standard fields and set the Item Type to Rental – Header or Sales – Header. Put the rates, deposits, damage waiver, link item, and kit items in the header item record. In each of the serialized items, enter the item key of the header item in the “header key” field. That is all you need to do to setup the header items.
When you add a package/suggested item to the header it will put those items on the contract for all serialized items as well, even if they select the serialized instead of the header. It does not need to be on the header and the individual serialized (adding it to both will add the package/suggested two times.
The Rental Header Item feature is most useful when reserving items. Instead of reserving or sending out a specific serialized item you can reserve or send out a Header Item. Then, whenever the specific serialized item is selected it can replace the generic Header Item.
The Sales Header Item feature is most useful when you sell high dollar equipment that you want to track each item sold by serial number, but you want to see the total quantity owned whenever inquiring on the item.
Notes:
The quantity and quantity out of the header item will be dynamically computed from all of the serialized items. So, changing the quantity of a header will have no affect since the quantity will be recomputed.
