 Example: Formula for Periodic Setup Locate this document in the navigation structure

The execution time of an operation is here defined as the sum of the times for setup, processing and repeated setup during processing. This can be expressed with the following formula:

F = SET + RUN * LOT / B + SET2 * ( ( LOT - 1) DIV SI

The meaning of the formula parameters and the origins of their values are given in the table below.

Setup time during processing

Standard value

The setup interval is here the number of items that are produced before setup is repeated.

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 two segments, you can use two formulas, F1 and F3 for the segments.

Operation segment set-up:

F1 = SET

Operation segment processing:

F3 = RUN * LOT / B + SET2 * (( LOT - 1)) DIV SI)

This is useful, if you are interested in the times of the individual segments.

Note Note

The formulas and parameters used here, F, F1, F3, B, LOT, etc. 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.
