I am using Aspire. In my metrics tab I am trying to show current inventory levels for our bulk material but I can not find a way to create something that will show my current inventory levels. Any help would be appreciated.
In Aspire when I select a piece of equipment and put in the service log the date and information the service does not leave my service due and I can not get it to say the service was done.
I am trying to create a metric to give me inventory totals after allocation to tickets.
