I can't update my dataverse table with primary/key column

Hello! Thanks for taking time to look at my question!

I built a dataflow that populates data from an excel sheet to a dataverse table. I set all columns to text and select which column I want to use as a key. The dataverse table is populated correctly.

I then change the dataflow's load setting from "Load to a new table" to "Load to existing table", select the same table, but the "select key" doesn't display my primary key column. I check the table and that column is a text field and is set as primary.

I don't know if this is helpful but this is being built in a dev/sand box environment.

Hi

A dataverse tables primary Key is a GUID. So you are trying to populate an existing table that whose key is defined as the default value of GUID, not a Text value (well its text, but you aren't giving it a guid)

So it fails as expected for what you have above.

If you look at your Table and you look at the columns you will have a Unique id that is a GUID, not the column you chose.

I cannot see anything as you just provided words.

But thats why it is failing.
