deleting records

Hi All,

I  have added one custom table using the RAP in contact screen (BP_CONT).  The custom assignment block having the one click action button 

" DELETE". When I click on "Delete" , it is directly deleting the record from database . It is not  reverting when I click on "Cancel" on overview page of BP_CONT. Those records should be deleted when we click on SAVE button . if we click on "Back" or "cancel" those records should be reverted in custom assignment block.

Note:- Created a lock for custom table in table CRMV_TBLOBJ_MAP.

any thoughts please.

regards, Ram
