RE: Due date changes suggestion to off hen using Planning worksheet
Hi Ishan,
Planning worksheet is always matching Demand Vs Supply with respect to demand date so if your supply orders (e.g. Production order, purchase order) due date is later than the demand date then system asking to change the dates of those supply order to meet the demand on time. however if you do not want to change the dates or do not want to have suggestion of changing the dates in planning worksheet then you can set planning flexibility of those supply orders as None.
Planning flexibility is a field which is available on purchase order line as well as production line so if you set it as None then system will not suggest to change the dates of it however system will also not consider this supply against the demand order (e.g. sales order, production order component) and will suggest you to make new order against it.
In case, if your supply order is earlier then the demand order then also system is suggesting to change the date later to exiting. you can overcome it by putting Dampener Period on item card.
