I've amended a Bill of Material for a bollard we manufacture to include an option to either paint it black, or have it galvanised (other paint colours to come).  I've set up the COLOUR feature as an O type item, with the option bill of material with GALV or BLACK as T Type items.  Upon entering a sales order for the finished part, it comes up with the option to either paint or galvanise the bollard.  However, the option does not appear on the final sales order, nor on the works order traveller and works order BoM/Routing.  What am I missing?
