[ic] Error attemping to add new field to products table

[interchange-users@interchange.redhat.com (Greg Cheak)]

Interchange 4.8.3 :: Hosted environment :: GDBM database

Attempting to add a new field "team" to the products table. Not certain of 
the correct procedure. Adding the new field name at the end of products.txt 
and importing into IC gives the following error:

There is no column named 'team' at 
/usr/local/cpanel/3rdparty/interchange/lib/Vend/Table/Common.pm line 232, 
line 1.

Clear enough, but the reference to Common.pm seems interesting.

Any help appreciated.
