Thanks Satish,
Soft block is not for address change.
Soft block is only relevant for asynchronous screening when a business partner or document has not gone through initial screening or you may say has not processed yet.
Even if you have setup your system for synchronous screening, system performs A1, A2 screenings only, automatically for a new or changed business partner and document respectively.
In case you have setup your system for asynchronous screening, the only difference is that you have to call these screenings manually or via batch job.
As far as I can recall right now, general status of document are always green before it starts screening process I.e. Processing status is 'available for processing' and technical mapping is 'complete'.
Secondly I suggest you to check BP SPL status by running S1 scenario.
Thanks,
