Hi,

although this is a VFP application, the problem is not really VFP related. Currently I have items that can be sold and multiple of those items can be added to an invoice (invoice line items). I want to allow the user to combine multiple of those items into one item that can then be sold with its own unique price (which is not necessarily a sum of all the prices of the individual components). What terminology is used to describe this? I'm thinking Bill Of Materials, but that doesn't "feel" quite right.

I am guessing that the data structure I need to implement is like this:

Items
ItemId
ItemDescription
ItemPrice

ItemsSub
ItemsSubId
ItemId
ItemQty

Does that make sense?
