We just turned on AX 2012 R3, and mrp is now running fine with one exception. It generates planned orders for items when we think it doesn't need to.
Example: MRP ran last night (starts at 11pm and finished after midnight of the next day) and generated a planned order for 1,000 pcs of part A. There are three open requirements for a total of 283 pcs of Part A three days prior to the planned order date. There is plenty of inventory to cover this. Without this planned order, mrp says we don't hit our safety stock still seven months later.
Part A has 2,487 on hand, 1,200-pc safety stock, coverage period = 91, lead time = 7, negative and positive days = 950, coverage fence = 730, action message checked, action time fence = 999, but others are zero.
I've read the forum and have seen the discussions that mrp first creates planned orders, then tells you to cancel. But in this case, we don't see the need. The worst part of it is our molding department has 300 planned orders to review after mrp runs, and the majority are unnecessary. We don't see how we can sort the truly necessary ones to run from the unnecessary without going through them all.
Is there a setting that we're missing? Has anyone developed a customized report to sift the wheat from the chaff? Or do we have to live with this?
Your help is appreciated.
