Objects are displayed on the object planning board when they have been included in a service contract version with an 'Order' or 'Actual costing' contract status. This board will provide you with a graphical overview of the different objects over time. This is particularly useful if you use service contracts as lease contracts, under which you lease objects to customers, and you want to see in which periods the objects are leased.
On the Object planning board, you can use and
on the vertical scroll bar to the left of the calendar to increase or decrease the number of rows.
