I think you have 2 issues:
Hi Kenya Castellanos,
Firstly, reference set will get the values only from the records which are already created.
To select any enumeration from association, you should not want to choose Reference set.
Instead, there are two methods to get it work.
1. In the form, place a nested dataview with datasource of context and entity is selected as Associated entity. Then, In the Nested Dataview add the dropdown widget and select the enumeration status from dataview2.
2. If you are Opening the NewEdit(form) page through microflow, you can use this.
when creating the main object, create an object for associated entity and associate it through change object event. and then choose dropdown(Status enumeration) from association in the form.
Hi, Kenya Castellanos
Please check ENUM attribute Read and write access of particular user given or not otherwise delete enum attribute and create new one
i hope it will be help you!
Thank you
