I’ll admit, after reading your post, I’m not exactly sure what you’re looking for. But I do want to offer a warning.
You may not want a report/summary that simply looks at CHANGE Suggestions. They often play hand-in-hand with NEW Suggestions. They really shouldn’t be reviewed separately.
Below is an example I wrote up for our Buyers a while ago.
In this example, we had (2) jobs requiring Qty (2) of a part.
Job A requirement is due on 4/24/2024.
Job B requirement is due on 10/31/2024.
We had an open PO for qty (4) due 12/19/2023.
Our buyer was confused why he was getting a NEW suggestion when we already had enough on order. The problem was, he wasn’t looking at the CHANGE suggestions. (He had turned them off in time phase)
In this case, MRP actually created both Change and New suggestions to optimize this situation. Yes, we had enough on order to cover demand. BUT, we only needed qty (2) on order right now for the first order. So MRP suggested reducing the existing PO to a qty of (2) (and another suggestion to postpone it based on the lead times in our system)… and then created a NEW suggestion to buy the other (2) closer to when they were actually needed for the second Job.
There are a TON of factors that play into suggestion calculations. But, in the case above, if you only looked at the NEW suggestion (like our Buyer did), you’d wonder why MRP was saying you should buy (2) when you already have enough on order to fill all demand. You’re not accounting for the CHANGE suggestion which says to reduce the initial order.
If you’re only looking at the CHANGE Suggestions, you’d be at a loss why MRP was saying you should reduce the order to a qty of (2) when your demand says you need (4).
NEW and CHANGE suggestions work together, in sequence.
Again, I’m not sure what your goal is… but I warn against evaluating the suggestions separately. You’ll only see half of the equation.
