It looks like your where clause is too general.
According to your statement, 'delete record from master_tb when key pk = key fk' is not specific.
you may need to say :
delete record from master_tb where detail.key = master.key
and master.key = :master.input_key.
you may cinclude an optional go_block(master block);
then your delete statement.
I would also do a check first to ensure that indeed a record exists for deletion.

u need to change relation type(go to relation prperties and change deletion behaviour property to cascading, whose default value is non isolating) between master & detail to cascading and there should be on delete cascade on the table.
