RE: MRP200 -- BPCS-L

We do have minimum balances on some items. I had thought it was primarily raw materials like these. I will have to check the BOM where used on these items to see if any of their parents have minimums. We do have inter-facility DRP and I had assumed that figure should show up in the total manufacturing allocations. I suspect that there is something generating a need, that is not showing up on MRP200, that should be on the report, to avoid this user confusion.

This is a report I rarely look at, so I have to rely on what is stated by the person who uses it all the time.

My user claims this extra stuff is happening with one particular facility, not the others, and wondered what we are doing differently with it to cause this, or if there is a bug ... my suspect list is humongous in terms of things apparently being done differently, at that facility, such as another report showing 12 pages of items there that have negative on-hand quantities with no transactions in 2 weeks & I wondering how often this stuff is checked, and what affect THAT has on MRP. I have to do a reorg at least weekly because of high volume of negative allocations. I sure hope that any figure that really is negative, is properly identified on vanilla BPCS reports.

Anyhow my user gave me a couple of examples. In both cases the minimum balance is zero. I checked our CIC a few days ago ... we not using any dynamic safety stock yet, but I see it looks like MRP200 would not print that info, if we had any just added.

One item printed has quantity 106 on hand with zero requirements.
(item 913311 Purchased Blocks) Order Policy Discrete

The other sample from my user has 73,000 on hand with 7,600 required.
(Item 914517 Terminals) Order Policy Discrete
I don't understand why we have 4,174 past due, when all the way across the report our on-hand is 10 times our gross requirements.

In both cases the lead time is 20 days.

Hi Al,

Quick question; does these items (or parent items) have minimum balances?  I
know mins will sometimes create those undesired requirements...

One of my BPCS users asked me how come,
when we run MRP200 we sometimes get items that do not need human attention.
Some pages have no requirements to make anything, and / or the on-hand
exceeds the requirements.
We are 405 CD Rel-2 & multitude of Y2K BMRs.
We have not modified MRP200.
We typically run it for planner 7 (raw materials that are REALLY raw
materials from outside vendors) in a certain range of item #s
BPCS documentation claims that it only lists those items which require
planning action.
We interpret doing something about excess inventory as something other than
planning action.
I spent a while looking at the documentation, and I do not have an answer
for my co-worker as yet.
