Actual Dates and Production Due Dates

All production IDs and production schedules maintain production date and shift information, as well as actual date and time information.

Production date and shift information is defined as the working day and shift (or manufacturing day and shift) during which component and production scheduling may be done. Define the production dates and shifts through the business unit's production calendar or the work center calendars. For example, on the production calendar for the month of March, you specify that you are working three shifts on 3/29/07. You just defined a production date of 3/29/07 with three production shifts: 1, 2, and 3. In this example, shift 1 runs from 7 a.m. to 3:30 p.m. When the start date and time or due date and time is determined, the time is converted to the appropriate shift. In this example, a start time of 2 p.m. would equate to shift 1.

Actual date and time is defined as the actual date and time the production is scheduled to begin or end based on the standard calendar. In most cases, the production dates and actual dates are the same. If you have production shifts that span multiple standard calendar dates, the actual date for production may be different than the production date. The system determines the actual date by the actual time that the production is scheduled to start or end within the production shift and the operation start quantity.

These examples explain and illustrate the differences between how PeopleSoft Manufacturing determines production date and shift information as well as actual date and time information when a shift:

• Begins and ends on the same calendar date.

• Spans multiple calendar dates.

Shift That Begins and Ends on the Same Standard Calendar Date

Suppose that a company runs seven days a week with one shift that starts at 7 a.m. and ends at 4 p.m. A production schedule can now be defined for a production due date and due shift. In the example, the actual due date is 3/25/07 and the due time is 3:30 p.m. Because this shift does not span multiple standard calendar dates, the production due date and shift for the production is 3/25/07, shift 1.

Shift That Spans Multiple Calendar Dates

For shifts that span multiple dates, define whether the start time or end time of the shift is associated with the manufacturing production dates. Define this option when setting up the shift codes using the Shift Codes page. Associate this shift code with a manufacturing production date and shift when maintaining production or work center calendars.

Based on whether you want the start time or end time of the shift to be associated with the manufacturing production date, the system first determines the actual date and time information and then the production date and shift information. These examples illustrate how the system determines the production date and shift based on whether you want the start time or end time of the shift to be associated with the manufacturing production date.

Example 1: Production Date Time Set to Start Time

Suppose that a company runs three shifts and the third shift starts at 8 p.m. and ends at 2 a.m. This shift is defined with the start time associated with the production date. A production schedule can now be defined for a production due date and due shift. In the present example, production is due to end on 3/26/07 at 1:30 a.m. Because the shift in which production takes place actually begins on 3/25/07 at 8 p.m., the production date and shift is recorded as 3/25/07, shift 3. The actual date and time appears as 3/26/07 at 1:30 a.m.

Example 2: Production Date Time Set to End Time

Suppose that a company runs three shifts, and the first shift starts at 10 p.m. and ends at 6 a.m. This shift is defined with the end time associated with the production date. A production schedule can now be defined for a production due date and due shift. In the present example, production is due to end on 3/27/07 at 5:30 a.m. Because the shift ends at 6 a.m. and the flag indicates the production date is set to the shift's end time, the production due date and shift is 3/27/07, shift 1. The actual due date and time appears as 3/27/07 at 5:30 a.m.

When defining production IDs, you specify the actual date and time information, and the system determines the corresponding production date and shift information. When defining production schedules, you specify the production date and shift information, and the system determines the corresponding actual date and time. For production schedules, you can specify the actual time within the production shift. In this case, the system determines the actual date.
