Hi Yohann,
MRP did take demand forecast into account. However, it did not take into account customer sellable days (the demand forecast line was specified per item and per customer).
MRP proposed to use on-hand inventory to satisfy the demand, which to me doesn't seem right. The requirement date on the demand forecast is 1st of December 2015. For that customer sellable days are set to 90 days. So, the expiry date for on-hand inventory that could satisfy the demand should be 29th of 2016 or later (1st of December 2015 plus 90 days). On-hand inventory has expiry date 26th of December, so that is not ok for the said demand.
"Consider shelf life" in MRP parameters is set. Is there any other setting that I'm not aware of?
Thanks,
Maja
