When viewing the Inventory results grid and individual stock units, you can choose to show or hide Costs.
Stock Unit – Main Detail
Stock Unit – Spec Lines
Organizations all account for expenses in slightly different ways. The additional cost calculation can be configured to include/exclude certain types. For example, when viewing stock units, some organizations do not want to see repair orders that are invoiced with these certain types (e.g. Sundry), because for them these expenses don’t go directly against the unit. This is an organization wide setting that can be defined by contacting support.
