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.

The Infor LN database must be created with the appropriate size. For example, if at least 150 GB is required for a year, create the database with the required size from the beginning. Do not let the size increase to the required size and cause additional fragmentation in the database and the NTFS volume.  Set the autogrowth to a minimum of 10 percent or 1 GB (for each extent) to avoid fragmentation on file system level. Never use the default extent size of 1 MB.

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.
