Datum Feature Label Has Syntax Errors
The datum feature label has syntax errors and cannot be processed. The value of a datum feature label must meet the following criteria:
May contain only capital letters (no numbers or special characters)
May contain any number of characters
May not include I, O, Q, or X
You can fix this problem in one of the following ways:
Using GD&T Advisor functionality…
1. Right-click on the feature icon in the Feature Tree that the datum is associated with and select Edit from the context menu
2. On the Edit Feature dashboard, specify a valid datum feature label
3. Select in the dashboard to accept the changes
