Example: Standard Formula 
In this example the execution time of an operation is defined as the sum of the set-up time and the processing time. This is expressed in the following formula
F = SET + RUN * LOT / B
The meaning of the formula parameters and the origins of their values are given in the table below.

Standard value |
You can assign just one operation segment, for example the processing segment, a formula to calculate the execution time of the whole operation. You do not assign formula to the other segments
Calculations with Several Formulas
Since the program adds together the times of the two segments, you can use two formulas, F1 and F2 for the segments.
Operation segment set-up: |
F1 = SET |
Operation segment processing: |
F2 = RUN * LOT / B |
This is useful, if you are interested in the times of the individual segments.
Note
The formulas and parameters used here, F, F1, F2, B, LOT, SET and RUN, are only valid in this example. In the SAP standard system formulas and parameters are defined for various applications with different formula key words and parameter IDs.
