SH-N  Generate Lead Times

Purpose of Program

Use this program to update the Lead Time fields in the inventory master records of all or selected ranges of manufactured items.  In the MRP module these lead times determine the start dates that MRP assigns to suggested work orders.

The Lead Time field, which can be viewed through IN-A  Inventory Inquiry, also serves as a reference on various screens and reports.

The program calculates the projected total run time days (using item's Lot Size as the quantity), which includes production run time, outside processing lead time, and any work center average queue time.  The Lot Size can be entered via the standard cost screen in IN-B  Enter Inventory, through IN-L-A  Enter Standard Costs, or via RO-A  Enter Routings.  The Lot Size represents the typical production quantity for this item.

Work center queue time represents an estimate as to how much contention (waiting time) there may be at each work center.  The program uses the Average Queue Time field in each work center, which can be entered through RO-C  Enter Work Centers.

When the program finishes its calculations it produces a report which lists any lead time changes that were made.

General Program Operation

You can limit the items subject to the lead time recalculation by entering from/thru ranges of item numbers, types (F-finished goods, A-subassemblies, M-manufactured items), item classes, categories, and cycle codes.  Lookups are available on the item number and item class fields by pressing the F2 key (or clicking on the Lookup button).  If you want all manufactured items' lead times recalculated, press <Enter> through all the fields.  The final prompt asks if you wish to print a report.  If yes, you will receive a report that lists items whose lead times were recalculated, showing the old lead time and the new lead time.
