creating connections in filemaker pro 13
I use filemaker pro 13 and use two startups inventory and invoices. I have products that I sell that are defined in invoices and I have included all these items by exporting them and integrated them into inventory. I want to create a relationship between both databases and I don't know how. I need to know how many products I sill have in inventory and when I sell one inventory should reflect that sale and what's left?
If anyone has a solution it would help!
