The projection of industrial demands is always based on billing data from a reference year. This makes it different for instance from the municipal and the tourist module, where for projection only the basic data (population respectively bed units) are used from the monitoring tables, but not the billing data.
Because the billing data are stored on quarterly basis, they have to be split into monthly values. By default the distribution is set equal between the months (33.33%). The user may overwrite the default values. The value for the third month of each quarter is automatically calculated in such a way that the sum for each quarter does not exceed 100%.
Data entry is facilitated by the button Apply 1st Quarter . This will forward the distribution entered for the first quarter to the remaining quarters.
Set to Default   will overwrite any user entries and set all monthly values to 33.3%.
