Problem: All controls for creating indexes in ArcCatalog are grayed out
Cannot create an index for a data field because the controls for creating indexes are grayed out.
To create an attribute or a spatial index, a single ArcCatalog session must be the only application accessing the data.
Solution or Workaround
- If the data is being viewed in ArcMap, remove, then re-open the properties dialog box in ArcCatalog to create the indexes.
- If the commands remain grayed out, it is very likely someone else is accessing the data from a different computer.
