Anyway, I was able to do something by redefining the V-Getter method for the status field by adding the following code:
DATA: LT_PARTNER TYPE CRMT_PARTNER_EXTERNAL_WRKT,
LS_PARTNER TYPE CRMT_PARTNER_EXTERNAL_WRK,
lt_req_obj TYPE crmt_object_name_tab,
lc_action_execute TYPE REF TO cl_action_execute,
lt_item_guids TYPE crmt_object_guid_tab,
lt_requested_objects TYPE crmt_object_name_tab,
lv_emp_guid type BU_PARTNER_GUID,
lv_user type SYUNAME.
INCLUDE crm_object_names_con.
INSERT gc_object_name-partner INTO TABLE lt_requested_objects.
if lv_object_guid is not initial.
INSERT lv_object_guid INTO TABLE lt_item_guids.
CALL FUNCTION 'CRM_ORDER_READ'
EXPORTING
it_item_guid = lt_item_guids
it_requested_objects = lt_requested_objects
IMPORTING
ET_PARTNER = LT_PARTNER
EXCEPTIONS
document_not_found = 1
error_occurred = 2
document_locked = 3
no_change_authority = 4
no_display_authority = 5
OTHERS = 6.
loop at lt_partner into ls_partner.
if ls_partner-PARTNER_FCT eq '00000014'.
lv_emp_guid = ls_partner-BP_PARTNER_GUID.
endif.
endloop.
if lv_emp_guid is not initial.
CALL FUNCTION 'BP_CENTRALPERSON_GET'
EXPORTING
IV_BU_PARTNER_GUID = lv_emp_guid " GUID of a Business Partner Address
IMPORTING
EV_USERNAME = lv_user " SAP System, User Logon Name
EXCEPTIONS
NO_CENTRAL_PERSON = 1
NO_BUSINESS_PARTNER = 2
NO_ID = 3
OTHERS = 4.
if sy-subrc <> 0.
* message id sy-msgid type sy-msgty number sy-msgno
* with sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
endif.
endif.
endif.
if sy-UNAME eq lv_user.
gr_step_status_ddlb->set_selection_table( it_selection_table = lt_ddlb ).
else.
read table lt_ddlb into ls_ddlb index 1.
if sy-subrc = 0.
append ls_ddlb to lt_ddlb_tmp.
endif.
gr_step_status_ddlb->set_selection_table( it_selection_table = lt_ddlb_tmp ).
endif.
Assuming that the partner function assigned to the checkpoint is Employee responsible.
Thanks,
