Open the History – Cost center page by navigating through Responsibilities > My Responsibilities > Cost centers > select cost center > History.

On the History – Cost center page, you can show all the cost center's changes (see My cost center history).

The information is divided out on to three tabs:

• Events: Shows all the events, which affect a cost center, either on a timeline or in a table (see Displaying my cost center history).

  TIP: To navigate along the timeline, click in the pane and move the mouse left or right whilst holding down the left button.

  To zoom in or out, turn the mouse wheel.

• Status overview: Shows an overview of all assignments (see Displaying the status overview of my cost centers). It also shows you how long each change was valid for. Use the status overview to track when changes were made and by whom. This way, you not only see the initial and current status but you also see all the steps in between.

• Status comparison: You can select a date and display all the changes made from then until now (see Comparing statuses of my cost centers). You can also show what the value of the property was at the selected point in time and what the value is now.

The following tables give you an overview of the different functions and content on the History – Cost center page.
