Hi Akshay,
Assuming you have the IOS# and the related data stored in the reference entity. When you enter the IOS#, you want to fetch all the information from the reference entity.
You can use an on change action and call a microflow. The first action would be to retrieve the correct reference object based on the IOS# (first from DB) and the second action would be a Change Object of the Object you display on this Page4, setting the corresponding values and refreshing. The Save button you could also change to a microflow action if you want to validate and store the information elsewhere.
Hope this helps.
Update: Depending on your use case, you could set up an association to the reference entity and select the correct value via a reference selector
Hi,
I want a similar dropdown option showing the matching entries in the IOS number field which can highlight and filter the data in the dropdown option.
