Use
Certain assignments during the life cycle of an asset change frequently, and therefore a record should be kept of the changes, both for reporting and for valuation needs. Examples are the assignment of an asset to a cost center, or multiple-shift usage of an asset during a certain time period.
Features
You can store the following assignments with different time intervals in the asset master record:
Data is stored in an unbroken sequence showing the exact day, with a "valid from" and "valid to" date. When you access a master record, the time-dependent data valid for the date of the request is displayed. If the assignment is different in other time periods, this is designated by a history indicator after the field. Using the "Field breakdown" function, you display the entries for a given field at the different intervals.

You can specify in Customizing whether you want the assignment to cost center and/or to business area to be time-dependent or not (under Master Data). For more information, refer to
Time Intervals
You can display the available time intervals and select them for maintenance. If you want to change an assignment starting from a certain point in time, you must first specify the new time interval. The system processes the data of the new interval and takes over the original assignments. The new interval can then be maintained.
