Hi @Nagraju ,

 

Have you tried lowering the RowsToFetchPerBlock value or reducing the frequency of refresh?

Hi Pardiles,

 

We raised the ticket with the microsoft support team,but we didn't get the proper solution, they are saying try to reduce the Row To Fetch Count only

 

our case we maintined 7k  As "Row to Fetech Count" then refresh  was worked properly

 

Thanks!!
