Column used as primary key

[Anonymous]

I tried to make a nested table.group and there seems to be some problem

here what i get when try to apply

You have an idea of what/where the problem lies?

what I can understand is the following 

the first external table.group make the first column of primary key type (?!) then when I expand the second internal table.group  the "keys" are duplicated and when in the close&apply panel the changes are applied some think goes wrong with the "relation".

the problem does not occur within power query

Make sure you turn off automatic relationships.

Remove relationships before applying in this case as part of the trouble shooting.

Now Apply, what comes in? Look at the Data view in Power BI.

I'm also not clear on what you are loading. Loading nested tables doesn't do anything for DAX.

Hi @edhans 

tanzk for the for the assistance.

Where, exactly, to make this setting?

"Make sure you turn off automatic relationships"

I found this panel where I manually deleted the various relationships one by one.
but I ask you if there is a more general way, as it seems to be indicated by you, to prevent the implicit search of the relationships between the tables.

It is in options.
