Quantity Determination: Example 
In the planning template, you have defined a row of object type "Stat. key fig." with the object "Employee". For the quantity, you branch to the quantity editor and define a formula. You use the function OWN_STAT_KEY_FIG in the quantity editor and select, for example, the statistical key figure "Salaried employees". In this case, the SAP R/3 System writes the planned quantity of the statistical key figure "Salaried employees" in the statistical key figure "Employees".
