Hi sweta pawar
Checkbox are not work in that way it is for multi select purpose, you can use enumeration or boolean for your requerement.
Hi sweta pawar,
Have a onchange microflow in the checkbox
In that microflow:
Retrieve from entity XPath: [id!=$entity]
Put that list in a loop, inside the loop, have a change object – change boolean=false
Have refresh in client set to yes.
Hope this Helps!
