Dataflow Gen2 Mashup Error

[Bdickers]

I connect to a sharepoint folder housing multiple excel spreadsheets that I combine using this Dataflow. I just moved those sheets to a subfolder (and adjusted my Dataflow to account for that) and now I get the mashup error:

Any help would be very much appreciated!

It turns out... when I was clicking through the 'Connect to data destination' tool the default was 'New Table' which didn't show the Date to Date/Time mashup issue. When I went back through and realized 'New Table' was selected, I adjusted it to 'Existing Table' and then the mashup issue showed up.

Surprised me adjusting this in the SQL Endpoint model didn't fix this, but either way the original error was the actual issue! Thanks for the help and sorry for the time wasted!

based on the error message shown in the screenshots, it appears that you have a mismatch of data types between your old mashup document and the new one that happens for a column that has datetime and it expects a date column instead. More information is provided in the error message.

what happens when you try to publish your mashup document? Do you get any sort of error message when trying to publish? Or is it only during a refresh operation ?

Thanks for the response Miguel! I double checked the column mapping and the data columns are all 'Date' types being mapped to 'Date' types.

Just to see if it made a difference, I went to the SQL Endpoint and changed the table field's type from 'General Date' to a specific Date format that does not include times. Same result. I may go ahead and publish to a new endpoint to see if that fixes it.

Same result.
