Calculating Lead Times
You can calculate manufacturing lead times for one item, a range of items, or a category of items. The calculation updates the lead time attributes of all manufacturing items that you include, regardless of whether you manually maintain an item's lead times.
Lead Times By Item Category
You can limit the items included in the manufacturing lead time calculation by specifying an item range or item category range when you submit the manufacturing lead time program. Using item categories, you can segregate the manufactured items whose lead times you manually maintain from those items you include in the manufacturing lead time calculation. You can also limit the parent items included in the cumulative lead time calculations by using item categories.
Recomputing Lead Times
Changes to routing and resource usages can impact an item's lead times. After each change you make to a routing (adjusting usages, adding operations, and so on), recalculate the manufacturing lead time for the item.
Prerequisites
You must define a bill of material for the parent item and member items who's lead time is to be calculated. See: Defining Bills of Material
You must define a routing for each item that will be used in the lead time calculation. See: Defining a Routing
You must define a lead time lot size for the parent item who's lead time is to be calculated. See: Defining a Routing
To calculate lead times:
Request: calculate or roll up lead times without a report.
Set: calculate lead times and produce either the Bills of Material Structure Report or the Routing Report.
3. If you selected Set in the previous step, select one of the following:
Calculate Cumulative Lead Times Set GUI: calculates cumulative lead times and produces the Bills of Material Structure Report.
Calculate Manufacturing Lead Times Set GUI: calculates manufacturing lead times and produces the Routing Report.
If you selected Request in the previous step, select Calculate Manufacturing Lead Times.
5. If you chose a specific item, enter the item.
6. Optionally, enter a revision for the item.
Enter the date and time to snapshot the bill or routing. All data effective as of this date and time are included in the calculation.
7. If you chose to calculate lead times for a range of items, enter a beginning and ending range.
9. If you chose to enter a category set, enter a beginning and ending category.
