I have a main report using a Dataset. I think have a List that uses a sub-dataset. In that sub-dataset I have a field returned that I want to pass to the sub-report as part of one of the parameters. Is there a way to do this?
Currently, if I do the Edit Parameters I can only see values from the main report and I don't see any values from the sub-Dateset that is used to populate the list. I tried to figure out of the Parameters Map Expression would work, but that does not work either.
Any assistance is appreciated.

I would like to begin by declaring that I may not understand your question.
Therefore, please understand that it may not be helpful as an answer.
* Assumptions of the report structure
main_dataset
--> parameters > Param_main
--> Variables > Variables_main
sub_dataset
--> parameters > Param_sub
--> Variables > Variables_sub
* Case1:main --> sub
list > Dataset > prameters
The setting here passes 'Param_main' to 'Param_sub'.
* Case2:main <-- sub
list > Dataset > Return Valus
The setting here returns 'Variables_sub' to 'Variables_main'.
Note that you need to be aware of the 'Evaluation Time'.
