  • Double-click on the datasource attribute table item;
  • Right-click on the datasource attribute table item and select Edit... from the context menu.
    Note:

    This also applies to table items of the other table item types.

The Edit Datasource Attribute window shows the following information:

  • The Name in data source and the Attribute type.
  • The Number of unique values and the Total number of records.
  • A preview of the values Value (Integer) and their Frequency.
