Thanks for your prompt response! I am using 9.3.0 and will not be able to upgrade at this time.
I attached the workbook; the Training Data data source has the Boolean field. The second and third screenshots were grabbed from this data source.
I confirm the data type convention menu with your Access data source.
It seems that, the data type convention menu differs according to data source type.
In case of Excel files and original fields (caculated fields excluded),
for fields currently with data type Date & Time or Date, "Geographic Role" is not shown.
for fields currently with other data types, the menu is the same as follows.
Date & Time
In case of Access database,
I see the same menu as your screenshots.
I guess that it has something to do with data source connector.
