Hello,
I need help please. I’m trying to figure out why Epicor is suggesting a PO in the middle of where we are negative, when none of it is actually needed. Placing this PO would create excess - AND the PO suggestion is still months after we go negative. I’m new to the company and IT can’t figure it out and said it’s possibly a bug.
The Planning time fence & lead time is incredibly long (working on that). Any insight of what to look for is appreciated.
You have demand that says you need them on those dates. The PO that you are highlighting is going to be very late. The system is saying that you’ll be out when you need them, so you need to make a PO. Seems perfectly logical to me. Imagine making a cake this weekend and you need two eggs. At this moment you have no eggs, but you are planning on buying 30 eggs in 2 months. Does that mean you don’t need eggs to make the cake this weekend?
MRP is a date driven system. You buy stuff when you need it, and to be able to know when you need it, you have to have real dates in the system. Real dates when you are going make it, and real dates when you are going to buy it. Otherwise how can the system do any planning? So until you move either your supply (the PO) or the demand, (the jobs) the system is going to try and tell you that you have a problem.
Thanks, my next question is if I go negative in January, why is it suggesting a PO in June?
I would have to look at your details to figure that out. That screen shot isn’t enough information to be sure. I would bet it’s a combination of change suggestions and new suggestions that’s messing with what you are showing. I’ve seen stuff like this many times, and I’ve never seen it be a bug in MRP. It’s always some setting that’s causing it to do that.
I’m curious about this. Are the dates and qty’s locked on the PO’s due on 7/5 and 8/9?
The new suggestion due in June makes sense based on your lead time and time fence. I’m wondering why MRP didn’t make a change suggestion to expedite and increase the PO’s that are outside of the planning time fence.
Why is MRP letting you stay negative for so long?
