Re: [WebERP-developers] MRP: Reschedules asks to cancel MTO, proposed PO's

[Phil D. <ph...@lo...>]

well with any significant lead times, it is imperative to enter a forecast if you don't have sales orders planned out for future deliveries. Of course it is impossible to make everything required immediately and MRP is all about planning for materials required, this needs to done ahead of time and hence a forecast of likely demand is critical. Guys running MRP need  to understand the process - if they don't then it will certainly fail.
Some tools to create a forecast based on historic data may be good though. However, these need to be applied by someone who understands the business and the implications. No forecast will be perfect in the absence of an accurate crystal ball. However, failure to forecast at all will certainly lead to stock outs  and lost sales.
