Numeric overflow error in webi

Hi all,

I have backend as Teradata 15 and frontend BO 4.1 sp5

after dragging objects in query panel,when I tries to run query I get 'Numeric Overflow Computation Error' in webi.

I have one measure column which has Decimal(20,2) datatype.when I drag that object in query panel in IDT;it shows some wrong format value.

means if value is 4,33,445,66.88 then it shows 4.33445668E7

In database it shows correct values but in IDT its format changes.

Can anyone give solution to it??
