Your issue most probably relates to the fact that you are trying to change the value of that USE_DATE parameter in runtime, which is not possible due to security. More information about it can be found in this
post. If you want to store values, that can be read by all components of a graph and dynamically change them via CTL code, you should use Dictionary instead. It's as easy to use as parameters and it's designed to be used this way. Please see more information about Dictionary
in our documentation.
Alternatively, if you need to use and change this value in just one component, you can simply use variables. Please refer to our documentation for more information about using variables
In case you still have troubles with the solution, please send me your graph, so I can better examine your issue.
Hope this helps.
