zero value variable not appearing in jde xml file

Hello,

I am working on the R42565 and using embedded BIP to handle the output.  The issue seems to be that the ube does not include a variable with a zero value in the xml output.  The company wants to have the totals fields always appear at the bottom of the invoice even if zero.  When I set the variable to zero if it is blank or null, it is not included in the xml.  However, if I give it a value other than zero in the UBE, the field appears as expected in the xml.

How do I cause a zero value field to show up in the xml for use in the template?
