Since we migrated to E10 a month and a half ago, we have started noticing very weird behavior with MRP and purchase suggestions. One of the things we are seeing is that there will be an approved, confirmed PO in the system for a certain material, but “Generating Purchasing Suggestions” will suggest…

Wow, this sounds like a similar problem that happens if you don’t have the “new” (sometime in E9) setting for “Allow Consumption of Minimum”. Search this out in the Help file, and my recommendation is that this setting should be TRUE. When you have this turned off, the system treats Minimum qty oddl…

[image] timshuwy: “Allow Consumption of Minimum”… my recommendation setting should be TRUE. I also like that “Allow Consumption of Minimum” = true will include a parts Lead Time in the Due Date calculation for new suggestions.

Thanks, I’ll take a look at that! If this isn’t new in E10 this wouldn’t be the first setting that didn’t migrate properly.

Sure enough, that checkbox was not checked. (The help file was no help in even finding this checkbox, but from another comment on this site I found it is in “Site Maintenance”). But after checking it and re-running “Generate Purchasing Suggestions” and MRP I am still seeing bogus suggestions. I w…

Here’s another example of how suggestions are messing things up. We have a part that has a min on hand of 100 with a lead time of 21 days, but currently there are only 75 in stock. There is a PO that is open, approved, and confirmed, for 250 pieces, entered 9/3 and due 10/10. Further, there is a …

I’m noticing in some of the parts I’m looking at, that a PO will be in process and scheduled for the part to arrive on a certain date, but the suggestion will be for that same PO at an earlier date. Is there some possibility that it’s getting confused? It seems to be demanding that the PO be resch…

This still looks like it is processing like you dont have the “Allow consumption of Min” turned on. The fact is that you are below min, AND you are consuming more taking you even more below min before the next PO is scheduled to arrive. Allow consumption is supposed to take the lead time into accoun…

two more things to do/check: check out the “Reschedule In/Out” delta fields… these are visible in Part/Sites/Planning as well as the more global settings in the PartClass Maintence (which allows you to control this for a whole group of parts). This setting is what I call “Noise Reduction”… you ca…

[image] Epicorus: but the suggestion will be for that same PO at an earlier date. Is there some possibility that it’s getting confused? Would not surprise me. I wish there were clear answer but… determining the reasons behind change suggestions can be an unrewarding exercise. For one thing,…

@timshuwy I would beg to differ that locking a PO allows new suggestions…
