Reading data from MySQL using Stored Procedure versus direct table access

[skgoel]

Hello Powerbi Users

I am facing a challenge in refreshing reports.

I created a report where data was taken directly from a table in MySQL.  Then I replaced the table with data returned by a MySQL stored procedure.  The structure of the data sets from both the methods (table and stored procedure) are exactly the same.

My challenge is that it takes 15 minutes to refresh the report if I use table as the source and 75 minutes if take data from the stored procedure call.  I am not sure why the report using the stored procedure approach is taking so long to refresh.

Can anyone help here please?
