Adding New Rankings and LP_CUSTOMER_RANK

Hello,

My Development department is adding two new levels to a membership organization. New constituencies have been created and assigned ranks but these memberships are not triggering the addition of the rankings to the customer record like the existing ones.

From what I gather an update to LP_CUSTOMER_RANK might  be needed but since this was created as part of our implementation I am not sure what I am looking for to update. Does anyone have experience adding new membership levels and updating this procedure to apply the rankings? Is there something else I am missing setting this up? 

Thanks!

Tim
