Purchase suggestion creating duplicate suggestions

So I am trying to figure out why the system is making duplicate suggestions. These are related to part purchased on a planning contract. There is something to do with the dates, but I can’t figure out where it’s getting the numbers from. I added a note in the log where the system is created a change suggestion, then jumping to a date, and creating new suggestions. Ones that aren’t needed. If I push out the process date on the suggestion window, these duplicates will go away, but they come back again whenever suggestions are run normally. So where do I look to set the system to look at all future demand and calculate suggestions based on that. (we are custom engineered to order, so we don’t have any standing orders or anything out more than 6 months, so looking to infinity is a big deal for our business). If anyone can give me a hint on what is affecting this, or can educate me on purchase suggestion generation, that would be greatly appreciated.

**Full disclosure, we do not use scheduling properly in our system. We just slam and order in there, and if there is a suggestion to buy something, the purchaser buys it, irregardless of due dates. I know it’s a dumb way to run a business but you learn to stop fighting fights you won’t win.

Here’s the log for a specific part that is having problems. I made a note where jumps ahead to a future date. I don’t know why it picked that date, or why it ignores everything else behind it.

Lead times for this part are set to 0 if that makes any difference.

Update, if I push out the process date on on purchase suggestions out a ways, it will calculate correctly. Can anyone tell me if always running this process date out a month ahead is detrimental in some way?

have you looked at Time Phase for this part? There are many reason why you will see this. The best place for me to start is Time Phase when troubleshooting MRP suggestions. Time Phase will show you the suggestions, such as canceling a PO or expediting it.

In your Planning Contract, do you have release dates set up so that you buy this part every x number of days? It could be giving you multiple suggestions because of that, especially if you don’t have Days of Supply set on your part.

You should have a lead time in there for every purchased part unless you can get the part the same day you order it.

Buying everything that is suggested is scary! That is a good way to inflate inventory quickly. Your purchasing agents should be reviewing Time Phase prior to purchasing until you get the kinks worked out.

Just my 2 cents…

Yup, the demand for the planning contract for this part is coming directly from the jobs. We don’t see anything in there that should be calling for this extra demand.
As far as releases, Per training at insights this year, there is no reason for us to put line in the planning contract, you simply link the PO to the planning contract when you order the parts. He orders some parts early depending on lead time (the purchase just knows…:roll_eyes:) and then everything that he didn’t order ahead of time is still link to contract, and the suggestion comes up the buy the rest to the contract once the job is built. The early order stuff comes from the designer once they know they need it, but before the BOM is finalized.

Since there are no lines on the planning contract, there are no release dates to be set. These are not stock parts (we don’t have much that we set up as stock) so they are only bought when we have a specific need coming up. They want to buy everything in as big of batches as they can.

I agree, but instead of doing to work to get lead times in there, he does do some reviewing of the time phase. The purchaser just gets testy when the suggestions aren’t perfect. I guess I don’t 100% blame him, what good is automation that you can’t trust.

I agree as well, and keep trying to tell them that, but management won’t do the work to get a realistic schedule into the system, so how would anyone know what to buy and what to wait on? Their solution is to buy everything right away, (they can move stuff around that way…) then get mad when they send out PO’s for the same thing 3 days in a row because they didn’t know that we actually have 12 weeks to buy something with a 3 day lead time.

But this goes back to picking your battles. I don’t mind my job and I kind of need it, so there you go.

And @Beth, you’ll get a kick out of this. I got in trouble the other day for not batching together all of the parts for 2 large jobs so that they can reduce how many set-ups they have to do :man_facepalming:

And they wonder why we are late on 70% of our orders…

Looks like you were on to something with days of supply. Since normally (pre-planning contract for us)only stock parts with mins and maxes set are purchased to inventory, the mins and maxes handle the days of supply. The non-stock parts were purchase direct and so each material sequence had a PO line to buy it to.

Now with planning contract, we are buying non-stock items to inventory. They items have 0 max and min (like they should) and since we’ve never bothered to set days of supply (honestly I didn’t think that would affect us since we don’t run MRP) this is the first time this combination has come up. When running a test, I can see the suggestion to reduce the PO. For some reason those suggestion doesn’t show up in the time phase for the problem parts that would have given us that clue (see above), however I think that’s what the system was doing was saying, since there is 0 max/min and 0 days supply it wanted to have a new release for the exact day. That’s why we only saw the issue with parts that had requirements for more than 1 unique day. Since we don’t have job built out unto the future (custom engineered stuff, no pre-orders), I can increase the days of supply on all non-stock parts to an arbitrarily high number and it won’t have an affect on our business.

I’m off to do some testing now. I’ll let you know what I find.

oh my… You have your work cut out for you!

Days of supply should help you. I’ll be interested to know what you find out in your testing. Good Luck!
