It would be nice to be able to copy:
- Tables between databases
- Exact same table, or just table structure (as clone works today)
- To other projects (but this could maybe be done by advanced import/export
- Fields between tables in whole project. (Exact same field)
- Dimensions, Cubes, OLAP Roles,Semantic models, Table inserts, custom scripts, views, project perspectives, Data sources, Databases...
In cases where the field is based on other fields not existing, the easiest could be to just remove these things, or set to empty, but the best would be if they stay the same, but with "invalid" marking on.
