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.
