Updating the Installed Base
The installed base is made up of records tying items with the end users that use them. These records can be created in various ways. Basically, records are either created manually, or various features of the system can be used to ensure that records are updated automatically.
Manually, with Installed Base Item Maintenance (11.3.1) and Installed Configuration Maintenance (11.3.5).
Automatically, when invoices are posted for sales or depot order shipments and RMA issues and receipts.
Automatically, from call tracking functions. When a call is closed immediately in Call Maintenance, you can optionally update the installed base. Otherwise, the installed base can be updated in Call Activity Recording for the item on the call and for items issued to repair it.
