The system automatically performs offsets for requirements dates for components in the MPS/MRP calculations. It also performs offsets for calculation of material need dates at the time that shop orders are released.

To calculate the offset, the system takes the parent lead time from the Item Master and adjusts it by the bill of materials offset (plus or minus) for the component. This gives the lead time days for that specific component. The system starts with the due date of the parent and backs up and skips all non-workdays in the shop calendar.

Note that the offset calculation uses only calendar records that have a blank work center (the calendar record applies to all work centers). See the information for the Shop Calendar Maintenance program, SFC140, in your Shop Floor Control documentation for shop calendar details.

For either file, you must specify a valid location code as defined in the Location Master File.

If the machine master locations are blank, then the work center locations are used. There are cases where you may want to do a combination between the two in defining the locations.

Let’s say the end item has one operation. The operation is at work center 510 and Machine A is in the work center. You have locations setup in both the Work center file and the Machine master File. You report 100 complete at the work center without specifying the machine.

In this case, the inventory will be processed based on the locations defined in the work center file. If the transaction included the machine number, then the locations in the machine file would be used.

You can move monthly periods to a different parent period. For example, if you have a monthly calendar, you can create quarter periods and move months to the quarters.

1. Select Financials > Global Ledger > Setup > Finance Enterprise Group > Maintenance.
2. Open the finance enterprise group.
3. Click the Calendar tab.
4. Open the calendar for which you want to move periods.
5. Click the Hierarchy tab.
6. Select the periods to move.
7. Select Actions > Move.
8. Select the new parent period under which you want to move the periods.
9. Click OK.

Note that the Bill of Material and Routing are revision controlled. When a structure is generated for the first time, a first revision is made with status New.

If the Approve Structures Automatically check box is selected in the Job Shop Master Data Parameter (tirou0500m000) session, the revision is created with status Approved.

If the structure is regenerated, the current revision status determines the result:

• If the status is New, this revision is overwritten
• If the status is Approved, a new revision is created
