I am attempting to map a field from Opportunity to custom entity. They are both option sets. The field has existed in the custom entity. Created new field in opportunity, put it on the form, published. In opportunity, I went to the N:1 relationship
to the custom entity, Mappings, selected the two fields, Click OK. Nothing happens. I've done this over and over and nothing happens. I've done this before but am I missing a step? Thanks.
