Calculate Inventory Usage action (Parts)

The Calculate Inventory Usage action enables you to calculate quantities and costs for the parts inventory, and determine the last date each part was used. Before examining the data of parts reports, it is good practice to run this calculation so that you can be sure that the part cost and quantity data is up-to-date. You can run the calculate Inventory Usage action from the following:

Navigator Path	Report or Task
Archibus SaaS / Maintenance / Part Inventory	Manage Parts Inventory View Parts by Vendor
Corrective Maintenance / Operational Reports Preventive Maintenance / Operational Reports	Current Parts Inventory (This task shows the Parts Inventory Information report.) Understocked Parts
Corrective Maintenance / Inventory Manager	View Parts by Vendor View Understocked Parts Define Parts Inventory
Preventive Maintenance / Background Data - Maintenance	Define Parts or Define Parts Inventory Review Understocked Parts

Calculations

This action makes the following calculations:

Value	Description	Calculation
Total Inventory Value	Uses the Quantity Available and Quantity of Reserved Parts and the Unit Cost - Set by User to determine the total value of each parts inventory	Total Inventory for each part = (pt.qty_on_hand + pt.qty_on_reserve) * pt.cost_unit_std (Users need to specify the standard unit cost value.)
Number of Vendors	Counts the vendors for each part in the Parts Inventory table	pt.qty_of_vendors = count, (pv)(Part Vendors table) values
Quantity of Understocked Parts	Determines if there are enough parts available to account for all unreserved estimates and the Minimum to Store, and if there are, sets the Quantity Understocked to 0. Otherwise, the calculation adds up the number of parts needed for all unreserved estimates plus the Minimum to Store, and subtracts this from the current Quantity Available to come up with the Quantity Understocked.	pt.qty_to_order = if pt.qty_on_hand >= (pt.quantity_min_hand + sum (unreserved parts)), then 0. Else (pt.quantity_min_hand - (pt.qty_on_hand - sum (unreserved parts))) where unreserved parts is calculated as the quantity estimated for part estimates that have a status of Not In Stock, or In Stock, Not Reserved (wrpt.status = 'NI' or 'NR'). See Part Status and Estimations. where the Field Heading for the fields are pt.qty_to_order = Quantity Understocked, pt.qty_min_hand = Minimum to Store, and pt.qty_on_hand = Quantity Available
Parts Usage per Year	Uses the parts assigned to closed work requests and inventory transactions of the previous 365 days to determine each part's total usage
Parts Usage per Week	Uses the parts assigned to closed work requests and inventory transactions of the previous 52 weeks to determine each part's average weekly use.	pt.qty_calc_wk_use = pt.qty_calc_yr_use/52
Current Year's Parts Usage	Counting from the first day of this year to today, the action totals the parts usage for each part from all closed work requests and inventory transactions
Last Parts Usage Date	Checks the last closed work request or the last inventory transaction to determine the date that each part was last used.

Update Average Part Usage / Year action

The Update Average Part Usage / Year action is available from:

• The Manage Parts Inventory task / Where Used tab
• The Equipment Parts (Equipment Bill of Materials tab) for all deployments.

This action updates the Average Parts Usage / Year shown in these reports. The Average Parts Usage / Year field is stored in the Equipment Parts table. The Calc. Parts Usage / Year field that is calculated by the Calculate Inventory Usage action is stored in the Parts table.
