on change date field change reference selector values which is filtered by custom data source
-metaObject (A) can choose 1 object from refrence selector (B) (i.e. the relation is A 1<---- 0 B ) and this reference selector is filtered by custom data source - on change date field of object (A) I called microflow which return the new refrence selector List data , but I dont know how to refresh refrence selector of object B to display the new data.
The reference selector will refresh it's dropdown list when the object of the dataview it is placed in (object A) is refreshed. The reference selector will refresh it's list by calling the microflow defined as custom datasource again.
So, on change date, you should trigger a microflow which contains a change activity for object A with "refresh in client" checked.
