Hi Vishnu
You are doing adaptation means you want to hide UIBB for all user for one system,Correct?
Then why no you are going for customization for this. SE80> Select Pacakge-MDG_BS_BP_BOLUI>select weddynpro Application >BS_ OVP_BP >select Appilication configuration-BS_OVP_CU >F8 and go for customization (You must add user parameter in your user profile as FPM_CONFIG_EXPERT with value A. Then update standard attributes for respective UIBB with Hidden element as Hidden
