the correct way to import numeric fields without decimal places is as following:
<Field dbName="TOTAL" type="Numeric" value="31" culture="en-US" decimalPlaces="0" />
for date and numeric fields, the culture parameter is always required. You should choose the one fitting for your localization.
If you are not sure which one you should use, have a look here: http://help.docuware.com/en/#b62903t59751n92298
