Hello,
I work with the S/4HANA Customer Management where I created some new fields in the "Custom fields and logic" fioiri app for business context service header and there they showed up and I was able to edit them as well as saving. Now when I try to add new fields for Opportunities I added some fields in the Opportunity Header business context, and I am able to see them and add them to the WEb UI, but the fields are greyed out and it is not possible to edit them.
Thanks for any help
