Use
In the planning table tab page and in the schedule lines tab page, the schedule lines created for the planned independent requirement items can be displayed as individual periods or as a total. The system can display every split of a planned quantity on a schedule line, or it can display the total quantity of a period on one schedule line. You can view the splits of this quantity by choosing the total. The schedule lines screen is clearer if you display totals, when the planned independent requirement items are split into daily quantities.
In the period totals display, the system uses the split used to create the planned independent requirements. The periodicity created in this first split is used in the schedule lines display. If you split these schedule lines into smaller periods, these schedule lines are highlighted but are still displayed according to the periodicity and the original quantity. If you choose one of these highlighted schedule lines, the system displays a dialog box listing the detailed schedule lines. You cannot change the schedule lines in this dialog box.

In the case of configurable materials, when you choose a highlighted schedule line, the system displays a dialog box of the configuration for maintaining usage probabilities. For more information see
Integration
In the requirements parameters or in Customizing, you can set the schedule lines to be displayed as a totals value or you can set all the period splits to be displayed online:
Select Reqmts parameters in the initial screen of Demand Management. In the requirements parameter screen, set whether you want to see the schedule lines as period totals or as period splits.
In Customizing for Demand Management, set per transaction whether the schedule lines are to be displayed as period totals or as period splits.

The settings made in Customizing can be overruled by the user-specific settings in the requirements parameters.
