Overview of shifts functionality
Manufacturing companies can use shifts to organize the production work force. The most common ways to do this ae one, two or three shift models, but more comprehensive models are possible that include for example only a single shift on the weekend or more shifts due to seasonal demands.
- Using shifts is mandatory for repetitive manufacturing.
- Implementing shifts is optional, because not all departments are, or can be organized according to this model. The use of shifts is defined per availability type.
Shifts are optional entities in a calendar code/ availability type combination. A shift is used to define the availability of a work center, for example a work cell in repetitive manufacturing. Each shift has a unique number key and is generated based on the shift pattern.
It is possible to generate shifts in the past starting from the first of January of the current year. Once shifts are implemented they can no longer be replanned until the current shift.
Shift reporting in repetitive manufacturing
The Report Shift (tirpt4636m200) session is used to manage and report the final results at the end of each shift.
In this session you have the option to amend preliminary bookings from the Work List (tirpt4602m000) session and up. If all data is correct, you can complete the shift, and update the related cost document.
You report a shift completed by specifying a work cell and selecting the applicable shift. Once the shift is selected, an overview of estimated work cell hours, labor hours and quantities is displayed based on the production schedule lines planned for the shift along with the quantities and hours already booked.
Set-up, run and down times can be reported through commands available in the Work List session, or calculated based on the quantities reported. The time booked may be less than the time available for the shift. This may occur due to booking discrepancies and can be corrected by the shift supervisor before the shift is reported complete after booking the set-up time and down time for the work cell.
If the hours are still less than the shift time after correction, the remainder of available hours is booked as wait time. Labor hours are booked the same way, the exception being that wait time for labor hours must be entered manually by the shift supervisor.
- A shift may contain multiple bookings, for example if backflushing occurs per transport quantity the quantity completed is booked every time transport quantity is reached.
- Hours are books as generic labor for the work cell, not per employee.
- If additional material quantities are used, you mast manually book the quantities to the point of usage that is linked to the material in the work cell cost document.
