BOL - creation of MarketingProject root object failed

Question

Dear All,
I'm trying to create MarketingProject root object in ABAP. I think the problem is with some parameters, but I've tried to provide the same parameters as an existing Marketing Project has, but still got 'creation failed'.
Part of code:
DATA:
lo_bol_core       TYPE REF TO cl_crm_bol_core,
lo_factory        TYPE REF TO cl_crm_bol_entity_factory,
lo_entity         TYPE REF TO cl_crm_bol_entity,
lt_params         TYPE        crmt_name_value_pair_tab.           
lo_factory = lo_bol_core->get_entity_factory( 'MarketingProject' ).
lt_params = lo_factory->get_parameter_table( ).
lo_entity = lo_factory->create( lt_params ).
or
DATA:
lo_bol_core       TYPE REF TO cl_crm_bol_core,
lo_factory        TYPE REF TO cl_crm_bol_entity_factory,
lo_entity         TYPE REF TO cl_crm_bol_entity,
lt_params         TYPE        crmt_name_value_pair_tab,  
ls_params         TYPE        crmt_name_value_pair.        
lo_factory = lo_bol_core->get_entity_factory( 'MarketingProject' ).
ls_params-name = 'OBJECT_TYPE'.
ls_params-value = 'CPG'.
APPEND ls_params TO lt_params.
ls_params-name = 'OBJECT_NAME'.
ls_params-value = 'Campaign'.
APPEND ls_params TO lt_params.
ls_params-name = 'DISPLAY_AUTHORITY'.
ls_params-value = 'X'.
APPEND ls_params TO lt_params.
lo_entity = lo_factory->create( lt_params ).
in both cases lo_entity is still INITIAL. I've tried to provide many parameters by inserting crmt_name_value_pair into lt_params, but it doesn't change anything. Creation from WebUI works with only two parameters - OBJECT_TYPE and EXTERNAL_ID. What's the problem in my case?
Thanks in advance

Hello Harshit,
I can read my collection with:
DATA: current TYPE REF TO if_bol_bo_property_access,
            lr_entity TYPE REF TO cl_crm_bol_entity.
current  = me-> typed_context->partner->collection_wrapper->get_current( ).
I can also read my customcontroller. But still cann't get the entity with:
lr_entity ?= me-> typed_context->partner->collection_wrapper->get_current( ).
Do you have another idea?
Thanks and regards,
John
