@rpathak not sure your issue in Diff snap or sort, can try below option in sort snap. Also if you are going to use Diff snap, both the side should have same set of attribute and name of all attribute in both end should same. Incase if any set of data you don’t have value, add mapper and put null or blank.
Thank you @Supratim. The name of all attributes on both ends is not the same, once update this issue has been resolved.
