If you select the Company calendar, you can enter a value for working hours per day in this field, in order to see which hours the calendar will generate per week, month and year. The default option is 8 hours.
If you select the Work center calendar, the system loads the basic time for that work center from the work center register, and this value cannot be changed here. You enter basic time in the Update Work Center procedure. Please see the Help Function for that procedure regarding basic time for work centers, under Basic time.
The basic time is multiplied by the factors in the work center and/or calendar, in order to calculate the capacity.
