Fetch Data based on the Input from Database

I need to extract the data from external database and load on the data grid after clicking on a button. I was able to fill data grid directly calling microflow from datagrid but I need provide below functionality to user Have text field that accepts input from user Search external database using user entered data as search criteria (Button click) Fill data grid with search results I tried calling microflow on button action and associated the corresponding output entity to data grid but its showing empty rows in data grid Any ideas on how to achieve this is helpful.

You may want to check your security settings (entity access), because empty rows often means that you were able to fetch the objects (eg trough a microflow of association), but you don't have read access to the attributes.
