In Order Time Can Make is an Inventory Status that is a calculation of the availability of the components required in the Bill of Materials to produce the finished Kit Item or Assembly Item.
The Can Make inventory status can be found on its own table in the reporting tool for the Inventory and Bill of Materials reports. There are two data fields in the table. The first is Can Make. That will be the quantity of the ITem that can be produced based on the availability of the required components. The second field is the Item Id. That allows Order Time to join the Can Make field to the corresponding Item.
