error message when executing a query or refreshing the workbook

Hi All,

Whenever I am trying to execute a query or refresh a workbook a error message is poping up saying that

Error: <internal error> Problem when writing table: E_T_cel.

I face this error in few of the queries and when i refresh workbooks. These queries have lot of calculations and filters and they sum up lot of records.

Any help greatly appreciated.

Thanks

Raj.
