I've set up collaborative forecasting on Product Families for my Org. However, I've recently changed the options in Product Families from 'A','B','C', to 'D','E','F'. Now, instead of the Forecast changing from 'A','B','C', to 'D','E','F', it shows all 6 of the combinations. I want to get rid of 'A','B', and 'C'. How can I do this?
'A','B', and 'C' have already been deleted as options from the picklist field itself.
