If I understand correctly: you have data available on page 1 and want to pass it on to page 2?
Make sure page 2 has a data view with the same entity as page 1 to pass on the object with the enumeration. Then from page 2 open a microflow with a parameter of that entity. Or if you want to run the microflow before opening page 2, make sure all links on page 1 to open page 2 open a microflow with a parameter of that entity. Do whatever you need and open up page 2 from that flow, while passing the object.
