Clear UDF contents

Hi,

We have a UDF in the header level of our ItemMaster data. The number in this field is used to calculate discount and new price.

The trouble now is that we need to remove all of these numbers using DTW, there are too many to update manually.

I tried using a / in the fields we want cleared but it seems to give the UDF a value of 0 instead of clearing it completely (I am assuming this is because the UDF is defined as a numeric value).

Is it possible to use DTW to "clear the contents" of a UDF, as opposed to replacing it with a "0"?

Many Thanks,

-Steve
