When the following report deleted when a BOL entity root entity, without having to manually report was also able to trigger a COMMIT WORK root entity actually deleted:
DATA: lo_core TYPE REF TO cl_crm_bol_core,
lo_collection TYPE REF TO if_bol_entity_col,
lv_view_name TYPE crmt_view_name,
lv_query_name TYPE crmt_ext_obj_name,
lt_query_parameter TYPE crmt_name_value_pair_tab,
ls_query_parameter LIKE LINE OF lt_query_parameter,
lv_size TYPE i.
ls_query_parameter-name = 'INTERNAL_ID'.
ls_query_parameter-value = '201300024498'.
APPEND ls_query_parameter TO lt_query_parameter.
lo_core = cl_crm_bol_core=>get_instance( ).
lo_core->load_component_set( 'CRMSMT' ).
lv_query_name = 'PostSearch'.
lo_collection = lo_core->query(
iv_query_name = lv_query_name
it_query_params = lt_query_parameter
iv_view_name = lv_view_name ).
lv_size = lo_collection->IF_BOL_BO_COL~SIZE( ).
"ASSERT lv_size 1.
DATA(lo_bol_entity) = lo_collection->get_first( ).
CHECK lo_bol_entity IS NOT INITIAL.
DATA(lo_root) = lo_bol_entity->get_related_entity( 'SocialPostRel' ).
lo_root->delete( ).
The reason is because CL_CRM_BOL_CORE-> ROOT_DELETE method is automatically called in CL_CRM_GENERIC_IL_NEW-> COMMIT operation.
And if you delete the root node following sub node:
REPORT zhana_product_search1.

CHECK lo_product->lock( ) = abap_true.
lo_text->delete( ).
After the discovery of calling delete, simply put the current sub node corresponding bol entity added to modified_entities tab bol entity manager's
To truly delete sub node, you must call if_bol_transaction_context the save and commit methods.
