itcsy structure

Hello,

I am calling a subrouting from SAP SCRIPT.

But in the subroutine I am not able to change the currecy value to integer.

FORM cal_Tot tables ntwr structure itcsy

tot structure itcsy.

DATA value type vbap-netwr.

value = ntwr-value.

ENDFORM.

If the value of ntwr-value is 300.0 its working but

if the value of ntwr-value is 1,345.0 this is giving runtime error.

How can store 1,345 into variable value
