Hi,
From what I understood you are importing some data and displaying them using data grid 2. Now you want to see the individual row data in editable form on the same page.
Create a Helper Object: Add a new helper entity, which will serve as the main object on the page.
Set Up Association: Create an association between the helper entity and your imported data entity (the data you are displaying in Data Grid 2).
On-Change Microflow: Add an on-change event to the Data Grid 2 that triggers a microflow when a row is selected.
Data View for Editing: Add a data view to your page, linked to the helper entity(from context association). In this data view, selected imported entity through the association will be show for editing.
Add a comment here if you have any more questions.
Best Regards,
