Entering Lead Time Information for Buy Lines

The system uses lead time information for determining the average lead time for the buy line, lead factor, and minimum lead samples. The system default values display in parentheses.

The lead time is the number of days it takes a vendor to supply stock, from the date of a submitted purchase order to the date of received shipment. The system calculates the median lead time days using the lead time factor for each product that makes up the buy line. You can use the median lead time or override the lead time for a buy line based on your knowledge of the products that make up that buy line. The lead time you enter to bypass the system lead time overrides any lead time set at the product level. The lead times set at the product level remain on the system, but are not used while the override lead time is set.

Seasonal products use a calculated lead time for that season.

To change the default lead time information for a buy line:

From the Purch > Maintenance menu, select Buy Line Maintenance to display the Buy Line Maintenance screen.
In the Dflt LdTm field, enter the number of days it takes for stock to arrive at the warehouse, from placement of a purchase order to the receipt of new products.
In the Ovrd LdTm field, enter the number of lead time days to use in place of any calculated or user-defined lead time for all products within this buy line. This field is optional.
In the Dflt LFctr field, enter the number of most-recent stock receipts that the system should examine to calculate the median lead time for this buy line.
In the Min Sample field, enter the minimum number of most-recent purchase orders that the system should examine to determine the lead time for products in the buy line. This factor works with the default lead factor entered in the Dflt LFctr field to create a time period for estimating the lead time days for a product.

If the product has not been received on this number of purchase orders, the system uses the value specified in the Default Lead Time Days If Product And Buy Line Have None control maintenance record to determine the lead time for the product.

Note: The minimum lead samples factor in this field only applies if one is not set at the product level. This factor displays in the Mn LF column on the Forecast Parameters Maintenance screen.
