# How to add maintenance time of machines into work orders dates

#1

dear all;
i have a problem .

I have table of work orders having start date and end date for-each row and minutes to finish the stage of work order

I have maintenance start date , maintenance end date , maintenance minutes , factory shift start time and factory shift end time

factory having weekly break is Friday and Saturday

how to expand dates in table by maintenance minutes ?

note :
WantedMinutsToAdd = 495 not 600 because start maintenance is '2015-12-06 11:45:00' and shift end time is 03:30 PM that mean the effected minutes = 11:45:00 AM - 03:30 PM = 225
and end maintenance is '2015-12-07 13:00:00' and shift start time is 08:30 AM that mean the effected minutes = 08:30:00 AM - 01:00 PM = 270
and else outside the daily working hours
600 - 495 = 105 is not effected because it is outside the daily working hours

## `DECLARE @StartMaintenance DATETIME = '2015-12-06 11:45:00' , @EndMaintenance DATETIME = '2015-12-07 13:00:00' , @MaintenanceMinuts INT = 10*60 , @ShiftStartTime TIME = '08:30 AM' , @ShiftEndTime TIME = '03:30 PM'

SELECT @StartMaintenance AS StartMaintenance , @EndMaintenance AS EndMaintenance , @MaintenanceMinuts AS MaintenanceMinuts,@ShiftStartTime AS ShiftStartTime , @ShiftEndTime AS ShiftEndTime
