How to utilise stored procedure via variable call?

[SJi]

Hello,

when I want to utilise stored procedure as a data source as shown on the picture below, I get an error message:

Unable to connect: Details: "Microsoft SQL: Error converting data type varchar to datetime2."

What am I doing wrong?

Hi @SJi,

Could you call the same stored procedure in SSMS successfully? 

The picture isn't very clear. Would you please share the stored procedure and Query you used in desktop? 

Best Regards,
