Consumming dataflows from a datamart

[DRISS-ELFIGHA]

I use a PPU Licence

I created a PPU Workspace W. I connected this workspace to an Azure Datale Gen2 storage account.
In W, I created a dataflow DF and I refreshed it

In W, I created a Datamart DM in wich I connect to the Dataflow DF.

When I clic on save, I get what showed in the attached image
I get the same error when I tried to create the Datamart DM in another PPU Workspace
If the workspace W is not connected to Azure, then NO MESSAGE ERROR

Hi @DRISS-ELFIGHA 

Which type of data source does this dataflow connect to? Did you notice that this error only occurs on a specific data source or it occurs on any type of data source?

Thank you for your reply

For the moment, I tested with a very basic excel table.  So the Dataflows DF is connected to a very simple excel tabe having 2 columns (id=integer and Libelle=texte) and 20 rows.
