Hi Dharama,
I wrote the below code, still it is not deleting the entities from Relationship child entity .
DATA:
   lr_current     TYPE REF TO if_bol_bo_property_access,
   lr_partnerset  TYPE REF TO cl_crm_bol_entity,
   lr_entity      TYPE REF TO cl_crm_bol_entity.
   lr_current ?= me->collection_wrapper->get_current( ).
   lr_entity ?= focus_bo.
   IF lr_entity IS BOUND.
     lr_partnerset = lr_entity->get_related_entity( iv_relation_name = 'BTHeaderPartnerSet' ).
   ENDIF.
   DATA: lr_bo TYPE REF TO if_bol_bo_property_access,
             lr_iterator TYPE REF TO if_bol_bo_col_iterator,
            lr_entity1 TYPE REF TO cl_crm_bol_entity,
             lr_col TYPE REF TO if_bol_bo_col.
   lr_partneropp = lr_partnerset->get_related_entities( iv_relation_name = 'BTPartnerOpportunity' ).
   lr_iterator = lr_partneropp->get_iterator( ).
*  lr_entity1 = lt_iterator->find_by_property( iv_attr_name = 'PARTNER_FCT' iv_value = '0000021' ).
    lr_entity1 ?= lr_iterator->get_first( ).
    WHILE lr_entity1 is BOUND.
      lr_partneropp->remove( lr_entity1 ).
      lr_entity1 ?= lr_iterator->get_next( ).
      ENDWHILE.
   lr_current->set_property( iv_attr_name = 'PARTNER_SET ' iv_value = lr_partnerset ).
