how to choose a appropriate lot size key and planning time fence
Our business strategy is that we make the process order in each Thu. and firm it until next Sun. Which lot size key and PTF are the most appropriate for us?
We choose lot size U1 and PTF 7days now.But we only want to firm the process order for one week. Under current setting, the firm zone will ratchet to another 7days in Tue. So the next planned order was firmed in a long time.
Thanks & Best Regards,
