Use this dialog box to calculate the manufacturing lead time for the part that is specified in the header portion of the Routings window.This is calculated from the operation list and default lot size of the part; it considers the setup, move, and operation times, as well as the efficiency factor entered for the operation. If the site is a CBS site, the calculation will also consider CBS overlap. The system also considers information about queue time and shifts, i.e., the number of work hours per day from the work center where the operation is performed. The calculation runs in the background, allowing you to continue working with the system as usual. The results of the lead time calculation are filled in the fields in Inventory Part/Manufacturing and in Inventory Part/Acquisition. The calculation separates the leadtimes into fixed and variable leadtimes by day and by hour. The times are displayed independent of lot size.
