Value calculation with time limitations |
|
The following example shows how values are calculated if lessons are date limited. Please look at lesson number 25 in the Demo2.gpn file. The factors in the master data should not be taken into consideration and lessons should take place between 03.10 and 02.03.
In these circumstances a value of 2.146 results. Looking at the school year calendar you can recognise how this value was calculated.
The school year extends over a period of 41 weeks (including holidays). However, there are only 22 weeks available for lessons. Dividing one value by the other (total weeks / lesson weeks) gives a distribution time factor that is used to multiply the value of the lesson.
The following calculation is performed: 4 * 22 / 41 = 2.146
School days only
As already mentioned, this calculation included weeks with school holidays. If you wish to exclude this you can also activate the “Count only school days” option on the “Value Calculation” tab under “Settings | Miscellaneous”.
Doing this means that only those weeks are included in the calculation in which lessons occur on at least one day.
If the “Count school days” option is activated the value in this example will change from 2.146 to 2.000.
The “Values for ‘count only schooldays’ ” tab in the calendar for the school year explains the changed value.
Deducting the school holidays from the school year leaves 38 weeks. There are 19 weeks available for lesson number 25. These two values are again divided, resulting in a distribution time factor of 38 / 19 = 0.5. If this time factor is now multiplied with the number of weekly periods for lesson 25 the result is 2.000
