You define the equipment categories for which you want an ongoing usage history to be kept in this step. Changes to certain master data fields will be logged in the usage usage history. You define the fields concerned for each reference category.
Using the usage history, you can, for example, define that changes to the account assignment data (e.g. cost center) are always documented in the system via the usage history.
This means that a change to the cost center in the equipment master record will always be documented by the system in such a way that you can display the equipment master record with the data contents at the time of the change to the cost center at any time.
In contrast to the change doucmentation with change documents, not only the contents of the cost center field are saved before and after the change, but the time-dependent data fields of the entire equipment master record at the time of the change are saved to the database.
The updating of the usage history is not possible for all equipment master record fields.
Exception: fields, whose contents do not usually change for business reasons, for example, the field Manufacturer or the equipment acquisition date.
The change to these field contents can however be documented using change documents.
If you do not want documentation for equipment changes via the usage history, you can still make changes to the equipment master records using change documents.
Define for which equipment category a usage history should be written.
