Calculation Rows 
Use
Calculation rows in the template create subtotals that you can use in multiple locations. You can define formulas and methods in calculation rows. You have access to any items in formulas via the activity quantity column and the activation column, and access to any items in methods via the activation column.
Example
You use three business processes in your template where the process quantity results from the formula " BomItemConsumptionRequired × 1.1". You define this formula in a calculation row and apply it to all three business processes.
( )
You can use plan values only in plan columns, but you may use actual values in both plan and actual columns.
End of the example.
