using same solution mentioned by @aishwarya but with a nanoflow is better for your performance.
this can be used on change of the date field and you don’t need to commit. in a nanoflow you don’t even need to refresh the object.
Hi Pragya Pandey,
For this, create a microflow and need to check the date field using the decision activity that is date < [%CurrentDateTime%]. And change the object to closed for true condition, and set object as open for false condition.
And return the object.
Hope this will help you!
