Error Saving File

devonkyle

I have an Excel file of financial time series data  that  I'm importing . I get an error every time I try to save the file with an attribute of ID. As long as I don't specify an ID, the file will save properly in my repository. If I try specifying my date column as an ID, RM refuses to save my file and I get the following message below. ALl the date values of unique values - no dups. I've even tried replacing the column of dates with a unique integer (1,2,3,4 etc) and I have the same issue. There are NO NULL values in this column. ANy idea what I'm doing wrong.??  I've tried this with multiple files with different attributes - same result. Thanks Devon

Hi,

this is an error we know and we already have fixed it. But we haven't made a release yet. Maybe there will be an update today that will fix it.

Best,
Nils

Just ran an update and it looks like it's been fixed! thanks for that... As a new user who is just learning the basics , I assumed I was doing something wrong - I literally spent hours trying to figure out what I was doing wrong before I posted in the forum.
