Auto-Fill Distributors selects lowest price without regarding Packaging Unit #887

System Information

How to reproduce

Obviously, it should fill in order number A as I only need the part once, so1*1€ < 1000*0,80€. Partkeepr has all information to decide which order number is the better one for this order.

This becomes a problem when using the octopart plugin which fills in the large order quantities from Digikey and others. This bug makes the Auto-Fill feature quite useless as it chooses always the order numbers with the lowest price, which is in most cases the one for are large packaging quantity.

In the last screenshot you can see partkeepr fills in order number B with order amount 1. But partkeepr knows that you can't order 1 piece of B for 0,80€, you would have to take 1000 pieces as you can see in the first screenshot.

I am having the same issue. Want to add some different price steps for resistors, as they get cheaper per resistor in higher volume.

This is related to #341 and #404. (As @xxv already mentioned)

However, I do not think that this is a "Backend" bug. This was fixed by me in the JS frontend, just created a pull request (see #341 or #404 for links to that request).

It is quite confusing seeing this as being classified as a "Bug" and the other issues as "Feature Requests". I think that all should be labeled as "Bug" because it does not make sense that PartKeepr would choose a distributor with a packaging unit larger than the part count.
