By default Pulse when documenting dimensions will only export the elements and attributes for dimensions with less than 5000 elements. This is to reduce the size of the source control system and to allow Pulse to efficiently document the whole TM1 Model.
This limit can be increased using the following parameter in the Pulse.cfg file:
MaximumElements = 5000
After changing this value you will need to restart the Pulse services.
WARNING: Increasing the value may cause Pulse to run out of memory if it is a very large value so use with caution.
