  • Hi,

    Can you provide the steps in details about how you configure the whole thing in you SharePoint Online environment and the Azure portal? It would make others easier to research on it.

    According to this error message, it is more like an issue that this user who views the External list has no sufficient permissions to the Azure database.

    Anyway, please follow this article to setup another external list, I have tested it in my tenant and it works properly for me:

    Please let me know once there any progress.

    Best regards,

  • I tried the link you provided I just have a question when it asked for the username password. Should I put here the admin of my SQL or my SharePoint Online account that has permission to the secure store info I <g class="gr_ gr_64 gr-alert gr_gramm gr_inline_cards gr_run_anim Punctuation multiReplace" data-gr-id="64" id="64">created.</g> Because when I added my SQL account it prompts me that "Access Denied by Business Connectivity Service" Can you clear this one out
