Problem: Tables appear to have no fields when using ArcToolbox Conversion tools if selected in ArcInfo Workstation Tables


When converting from an INFO table or coverage Feature Attribute Table (FAT) in ArcToolbox, the table(s) doesn't show any of its items if they are open in the TABLES module of ArcInfo Workstation.

Then a warning is produced after clicking the OK button: "An error has occurred while running 'tool name'. Unloading the tool."


The tool(s) requires a list of the items in the INFO table. If the INFO table is selected in ArcInfo Workstation's TABLES module, a read-only lock is placed on it. Hence, the table will appear to have no items or only one item (rowid).

Solution or Workaround

Before converting an INFO table or coverage FAT, make sure TABLES does not have the affected INFO file (standalone INFO file or FAT) selected.
