SALES_DATA custom series not defaulting value

Hi,

We have created a custom editable series on SALES_DATA table that takes a value of either 0 or 1, and a server expression that defaults a value of 0 when it is null.

When new combinations are created after Demantra collections is run, we find that the custom series is not defaulting a value of 0 (i.e. it is null).

Do we need to add this new column to T_SRC_SALES_TMPL to get it to default a value?

Cheers!
