Hi there, 

Sure it can be done but how?
This very common job takes at least two tables : one with a list of items and one with the inventory lines (very much like the invoice examples less the customers table) with a link in between those two.
Does it necessarily want a third table called "inventory", of which the "inventorylines" would be a composition (sub-table)?

The purpose would then be to import a csv file - only with codes and quantities - in the sub-table (or otherwise) - in order to have an immediate total value of the stock showing the description (and prices of course) picked up in the list of items.

Thank you
