Hi Ashwini,

previous object is not accessible in an async business rule because async business rule doesn't run immediately when record is inserted/updated instead it runs at specific time in backend after the transaction of insert/update happens i.e. asynchronously; hence system won't know what was the previous value for any field hence previous object won't make sense in that business rule

Mark Correct if this solves your issue and also mark Helpful if you find my response worthy based on the impact.
Thanks

The "previous" object is not accessible in an asynchronous (async) Business Rule because an async rule runs after the original database transaction is complete. Since the transaction is over by the time the async rule executes, the system doesn't have access to the record's state before the changes were made, making the "previous" object unavailable.
