Create calendars
The next step in the process of setting up calendars and resources is to create the calendar. You need to set up calendars before you create resource groups. The reason is because, when you create a resource group or a resource, you need to specify in which calendar the system should use it. Accordingly, calendars serve as the basis for calculating the capacity of the individual resources.
Use the Calendars page to create one or more calendars to manage the working hours to use in resources and resource groups. If you create more than one calendar, it's best to create a base calendar first. To do so, go to Production control > Setup > Calendars > Calendars.
If you edit the base calendar, the changes show in all other calendars that you create. However, if you change individual working time calendars, the changes aren't updated in the base calendar.
The Base calendar field defines what the current calendar inherits from the defined base calendar or possible base calendar. When the system updates changes to the calendar, the current calendar inherits operation times from the base calendar. However, the operation times template that's defined for the update controls the update. You can clear the base calendar when you update operation times.
The Standard work day in hours field is only required for lean manufacturing.
After you create a calendar record, you can edit the working times by selecting the Working times button.
Compose working times
You can use the Working times page to contain a record for each calendar day of the year. Define working times by entering times individually or by copying the information in the calendar and making relevant changes. Enter the typical work days and times that people use in your production, and then enter consistent variations to these times, such as holidays or weekends.
You can use the Compose working times button on the Working times page to specify which calendar to use to create the working times. Additionally, you can use the button to define the period of time for which the system updates the calendar. Alternatively, you can select an already-defined working time template.
When you set up the calendars and resources groups, you can associate them with each other. To do so, select the appropriate resource group on the Calendars tab of the Resource groups page.
