To increase the number of transition groups allowed follow these steps:
1. Open the VDDT database you are working with using MS Access and open the Global Settings Table
2. Change the field MaxGrp to the number of transition groups you would like to be able to use (the maximum number is 255).
3. Open the Project table and change the number of characters in the field DisableProbabilisticTransitions to equal the number of transition groups you would like to work with by adding the required number of capital F’s to the end of the string. For example, if you want to work with 50 transition groups you would need to add 20 F’s to the string (30 default + 20 = 50). This change must be made for every Project record in the table.
Note that Path automatically configures the VDDT database to handle the required number of transition groups at runtime.
