Multiple PO Suggestions for One Item?

Curious if anyone else has had this issue…

PO suggestions is showing two different suggestions for the same item, due on the same day, with different quantities. We are single site and only have one supplier for this specific item, so I’m confused why it wouldn’t be combining these into a single suggestion.

What am I missing here? Thanks!

look at the set up on Part → Site Detail, you may have a max lot size or other setting there causing this.

There are lots of variables that could cause multiple suggestions for the same part number. Are both suggestions for inventory? Or one for a Job Material? Buy to Order?

Is one or both of them buy direct to a job?

Show some screen shots of time phase, the suggestions, and the part set up, and someone may spot a setting that could cause that.

Also, check out ‘Time Phase’ to view the demand for the part. That should show unique entries for the two suggestions and display the difference between where the demand is coming from.

Both min lot size and max lot size are set to zero. Multiple is set to 1, and days of supply is set to 10.

On the Part Class there is a split PO Line checkbox we use that will split a suggestion based on the comment. We use it to seperate rated orders.

From Help
Split PO Line

Indicates that purchase suggestions for part records with unique Purchasing comments should generate a different purchase order line for each part entry.

Example: Part DSS-1000 is requested by two different operation lines on a job. If this check box is selected and the Purchasing comments are different for each operation line, the parts are kept as two different purchase order suggestions. If the check box is cleared, the parts would be combined into a single purchase order suggestion.

Interesting! I didn’t realize this was an option. I just checked and the split PO line is not checked for the part class associated with it.

I guess in addition to all of the good suggestions above, I would run generate purchasing suggestions for the part with suggestion logging on and see if there are clues in there.

You will need to go to server file download for Company type

These are PUR-STK. Here are the images of Part Entry, PO Suggestions and Time Phase. All three refer to the same part and we only buy that part from one supplier.

This is what’s doing it. Because you are going negative (aka you’re dates aren’t matching reality) it’s trying to push PO’s around on you. You’ll find that if you get your jobs on realistic dates, your planning will work as expected.
