Bala and Sudhir,
A colleague of mine notified me that there was a new feature created by the Agentry platform team to support the discussion I specified above wherein once you have applied you cannot go back. Note that this is a new feature.
The Work Manager team used this new Editor function (SMP 3.0 SDK SP09) and created an SAP note # 2212312 - SAP Rounds Manager and SAP Work Manager - Unable to Activate the Back Button to help resolve this problem (you will need to remove the Apply) - read article.
Hope this helps,
SAP Mobile Support Team
