Run time error in GR

Hello,

My user is having following issue.

Vendor has sent 3 items, out of which one is free sample. But on that excise has to b paid by us (which is approx 3000rs). So when user is trying 2 do GR, first 2 items dont hav any problem, but after checking ITEM OK tab in case of 3rd item(which is free sample), system shows following run time error

(Error in ABAP application program.

The current ABAP program "SAPLJ1IEX " had to be terminated because one of the

statements could not be executed.

This is probably due to an error in the ABAP program.

A value does not fit in a calculation field..)

What may b the remedy for it. How 2 handle this?

Thanks.
