Data Refresh Fails, Error message claims duplicate ID value in table
PowerBI Refresh ErrorSQL QuerySQL Result
Hi, here are images from PowerBI and SQL.
There is not much DAX in this data model. There are a series of Measures to cacluate the "Latest" SWC since each row has a unique data time stamp. The SWC table has some modifications in the Query editor, some look-up columns are expanded and the date column is duplicated so that I can have the date in multiple user readable formats.
Try doing a Trim and Clean on that field in Power Query. If you have it in there with a trailing space, for example, or maybe a leading zero I believe the model will consider that a duplicate but your SQL will not find that.

No dice, which I can't say I'm suprised. We authored the application that is filling the SQL DB and while our app is not perfect, one part that is rock solid is the SWC ID. Its the unique key for that table in SQL too, so SQL will not allow duplicates (though I agree there can be situtations where something might not be seen as a dupe by SQL).

Here's what I would do. Create a new Power BI file and copy over your query for this table. Run the import/refresh. Since it is not part of a relationship, you will not get that error and then you will be able to better assess what is causing the duplicate issue. I can't imagine you are getting that error on a lark, something is causing it.

Yeah, that is more or less where I've gotten to. Made a copy of the PBIX and started to isolate and delete stuff to see what came of it. Looks like I found a relationship causing the issue. We'll see.
Thanks for replying though!
