I have two polygon datasets which I join spatially 1:1 keeping all target features (the centroid of the one lying with the polygon of another).
Both datasets are layers in a map, and the target dataset has aliases. The resulting dataset loses all the alias information from the target (and possibly also the joined dataset, but I am not sure about that -- my joined polygon dataset did not have aliases before the join).
I daresay I would see the same thing were I to join points to polygons, but, again, I have not explicitly tested this.
Why is this? If I have gone to the trouble of creating aliases for fields, is it probable that I would wish to have those discarded?
(Arcmap desktop basic 10.7.1 on windows 10. All patches apply to both)
The behaviour appears to be different in ArcGIS Pro in the table for field properties for a layer
These settings also apply to fields that are appended in a join, although you are only able to edit the joined fields when they are accessed from the origin table.
