Hi,
We have a option set with a list of product category which is in the opportunity form, we are discontinuing one of the product category so i am trying to remove the product category in the option set. But when i do it all the opportunities created earlier which had the product category that i have removed is also changed and there by returning to Null, is there a way to overcome this.
I want all the opportunity which had the old account category to stay that way but the same account category should not be visible for the new opportunities that are created.
