Read EEW fields from BOM Object

Hello eWM Exports,

i try to read the EEW enhancements of an outbound delivery item in BADI: /scwm/if_ex_dlv_det_proctype~change_proctype.

At this time of the distribution of the outbound delivery from ERP to eWM the delivery is not persistent in the DB.

So i have to read the BO objects from the memory.

How can i access the customer own fields (from EEW) of an outbound delivery item.

I can not find any fitting structure/method to access it.

    DATA: lo_item   TYPE REF TO /scdl/cl_dl_item,

          lo_bom    TYPE REF TO /scdl/cl_bo_management,

          lo_bo     TYPE REF TO /scdl/if_bo,

          lo_header TYPE REF TO /scdl/cl_dl_header,

          lw_msg    TYPE string.

    CHECK  iwa_item IS NOT INITIAL.

    TRY.

        lo_bom = /scdl/cl_bo_management=>get_instance( ).

        lo_bo = lo_bom->get_bo_by_id( iv_docid = iwa_item-docid ).

        CHECK lo_bo IS BOUND.

        lo_header = lo_bo->get_header( ).

        CHECK lo_header IS BOUND.

        lo_item = lo_bo->get_item( EXPORTING iv_itemid = iwa_item-itemid ).

        CHECK lo_item IS BOUND.

        lo_item->?????????

      CATCH /salt/cx_ewm.

        MESSAGE i018(/wwit/wgi) WITH iwa_item-docno iwa_item-itemno INTO lw_msg.

        io_log->add_message( ).

      CATCH cx_static_check.

    ENDTRY.

Thanks Christian
