When using the ADI Integration, there’s a low chance that you will see duplicate parts appear.
If you see this behavior occur, then check the Part Edit and look to see if the Vendor is listed twice. The same vendor can be listed twice at different quantities, but if it is listed twice at he same quantity this is a data error.
What’s occurring in the data is that the IN_Part_Supplier has two entries for the Vendor, which is causing the integration to pull two entries when it runs.
To resolve, you simply need to Delete the extra vendor on the Part Edit.
