When implementing sync criteria, a "Verify" or "Validate" button which evaluates the criteria and shows how many items it matches, would be very helpful.
It would negate the need for test syncs to to test criteria, which are more time consuming and potentially risky in production.
Upvoted for this. At least, if the verify option helps to validate the rule like below would be great.
1. if the rule satisfies the syntax
2. If the fields or values included in the rule are acceptable based on master/target systems
3. May be showing up less no of sample records or total matching count as pulling all the records might consume time
