Removing DN from LineGroup

I don't think this is possible but thought I would just check.I want to remove a DN from associated line groups.

However I don't want to  care what line groups its a member off or know .I just want to remove it from all of them.

Is there away of doing this , it looks like you need to know the line group name using "updateLineGroup"

It looks like the relationships between lineGroups and DNs is held in the table "linegroupnumplanmap".  You should be able to construct a DELETE SQL query via <executeSqlUpdate> to delete any records where the fknumplan matches the pkid of the DN you want to remove from all groups.

Thanks , I hadn't thought of that , will have a look
