How to show mapping columns in Select - Data flow

Hello everyone,

I'm having an Issue with the Select tool in Azure Synapse.

When plugging it with my source, it doesn't show the columns to mapp.

Am i supposed to activate/disactivate something ? Is there anyone having the same issue ?

    Hello 16536432,

    Welcome to Microsoft Q&A

    It looks like the schema is not properly imported (or the schema might have changed)

    on the source dataset, please click on Import schema

    and then on the select transformation, click on "reset". You will see the column mapping after this.
