Requirement:
I would like to get Product sales status id via ABAP code. The test product id: 1467

In TJ02T, we know the status id is: I1050

Approach1: use function module CRM_STATUS_READ.

 METHOD read_prod_sales_status.
    DATA(lv_guid) = get_guid_by_id(iv_prod_id).
    CONSTANTS: gv_salesa TYPE comm_pr_frg_rod-fragment_type
     VALUE '37D58F1B772D53A4E10000009B38FA0B'.

    DATA: lv_objnr  TYPE comm_pr_frg_rod-status_object,
          lt_status TYPE STANDARD TABLE OF jstat.

    SELECT SINGLE status_object FROM comm_pr_frg_rod INTO lv_objnr
       WHERE product_guid = lv_guid AND fragment_type = gv_salesa.

    CHECK sy-subrc = 0.

    CALL FUNCTION 'CRM_STATUS_READ'
      EXPORTING
        objnr            = lv_objnr
      TABLES
        status           = rt_status
      EXCEPTIONS
        object_not_found = 1.
  ENDMETHOD.

Output:

Approach2: use BOL API

Method signature:

Source code:

METHOD get_prod_sales_status_via_bol.
    DATA:
      lo_collection    TYPE REF TO if_bol_entity_col,
      lv_view_name     TYPE crmt_view_name,
      lv_query_name    TYPE crmt_ext_obj_name,
      ls_parameter     TYPE genilt_query_parameters,
      lt_sel_parameter TYPE crmt_name_value_pair_tab,
      ls_sel_parameter LIKE LINE OF lt_sel_parameter.

    lv_query_name = 'ProdAdvancedSearchProducts'.
    ls_sel_parameter = VALUE #(name = 'PRODUCT_ID' value = iv_prod_id).
    APPEND ls_sel_parameter TO lt_sel_parameter.

    DATA(lo_result) = so_core->query(
        iv_query_name               = lv_query_name
        it_query_params = lt_sel_parameter
        iv_view_name                = lv_view_name ).

    CHECK lo_result->size( ) = 1.
    DATA(lo_product) = lo_result->get_first( ).

    DATA(lo_dc) = lo_product->get_related_entity('ProductDistrChain').
    CHECK lo_dc IS NOT INITIAL.

    DATA(lo_salesa) = lo_dc->get_related_entity('ProductDcSalesa').

    CHECK lo_salesa IS NOT INITIAL.

    RV_STATUS = lo_Salesa->get_property_as_string('STATUS_OBJECT').

  ENDMETHOD.

Define a static attribute so_core and initialize it in class constructor:

method CLASS_CONSTRUCTOR.
     so_core = cl_crm_bol_core=>get_instance( ).
     so_core->load_component_set('PROD_ALL').
  endmethod.
