Question : Expression result length exceeds the maximum. 8000 max, 16000 found.

When I execute a stored procedure using default params which are NULL

execute  prSgSingPrintCont  default,default,default

I get the following error message


Server: Msg 212, Level 16, State 1, Procedure prSgSingPrintCont, Line 1152
Expression result length exceeds the maximum. 8000 max, 16000 found.


The error message appears to be happening when executing the following code:

Insert into #Res (iOrderNumber, iOrderLineNumber, chRevItem, TotalArea, TotalExTax, chFlag)
   Values (@OrderNo, @OrderLineNumber, @RevItemCd, @TotalArea, @TotalExTax, 'U')

all variables at this point are NULL. The SP is quite big let me know if i should paste it in. When I exeute this outside the SP it works. Point to bear the SP and schema were recently updated to use nVarchar.
