Using the Wrap Character in the Flat File Schema

I have to send a Flat File with each text field with the wrap
character “”. I have requirement that if the field has no data there
should not be any “” in it. But when I make the wrap Character for a
field, by default there is “” in the output irrespective of there is
data or empty. How can I handle this.

I am getting output as

“ABC”, “”,”ABC,DEF”,”[email protected]”

“UVW”,”XYZ”,”UVW,XYZ”,””

But I want it to be

“ABC”,,”ABC,DEF”,”[email protected]”

“UVW”,”XYZ”,”UVW,XYZ”,
