Field Overflow error during GR of purchase order

Hi Experts,

While I am trying to do a GR of purchase order in CB1, I am getting the following error "Field overflow. Field: OUTPUT ; Value: 1,0752688172043011E+10".The PO quantity for the material is 25,450 SF.

The conversion maintained in the system is 1000SF = 93 SM.

When I change the PO quantity from SF to SM,then I am able to do the GR of the purchase order.

Can you please help me out,why am I unable to do the GR for the purchase order with order quantity as 25450 SF?

Thanks in advance,

Harsh.
