Set 'Applies To' ... 'Manual Property Definition'.
On 'Items' tab, create two items. True, and False.
In the PropertySetDefinition where you have Manual Properties set to 'True/False', change the Type to List.
Edit the Source to your 'TrueFalse' List Definition.
Set the default as you wish.
Edit the Schedule Style.
Ddelete the Columns that use the now broken True/False functionality.
Replace the Columns you wish to show TrueFalse Dot symbol with a Formula Property.
The formula should use Select Case statement as follows. See attached image.
Formula Properties defined in the PropSetDef will not result in the schedule using a 'Dot'.
Format has to be 'Unformatted'. Both the format control as well as the one in the 'Enter Sample Values' panel. I have found this to make a big deference. If this format is not set accordingly, the result will not be properly evaluated.
The Select Case works, but the otherwise equivelant 'If Then' statement does not.
