Whenever I create a new feature class with ST_Geometry column, It's created without any issue but I cannot insert data into it until unless I remove the spatial index from it.
I have tried the following things:
1- Also when I delete the Spatial Index I can enter the data and all works fine but
2- Later if I want to create a spatial Index on the same layer, it doesn't work. I can click on the "create" button but no spatial index name appears or
3- If I do it through the tool it says "Succeeded" about the spatial index creation but cannot see the index.
4- Rebuild Index button is disabled.
Any suggestion, why is this behavior and how to fix it?
ArcGIS Desktop 10.6.1, ArcSDE 10.6, Oracle 19c.
