Thanks for your answer, indeed I was not saving the references file before updating the properties values but saving this file before launching my load test doesn't solve the problem.
I also tried to use TestSuite-level properties without success.
The "Limit" value doesn't seems to be configurable using property (when I enter ${#TestSuite#LIMIT} as value in the limit field and then click on other field, the value of the "Limit" field gets back to its old value - without property).
The "Rate" value seems to accept a property-based value (I enter ${#TestSuite#RATE}) but, when I launch my load test, the TPS value doesn't match with the rate-property value (for example 50) but match with the rate value setted before the property (in my example 90).
