I am in the Process for using the Sign Inventory Solution Manager. What my Public Works department wants to do along with this is to be able to attach what they have in the Solutions inventory feature layer, subtract it from the Inventory in the Whare House. So in Other words if we have 50 Stop Signs in wharehouse and we Put two at four way stop. I would like to be able to show that number then as 48. If I could calculate this in a Dashboard along with some other Items that would be Great. Has any one done this or anything like this?
