Inventory by vendor report

Question

Hello all,
Users have asked me to create an inventory report that combines data from MCBE and MCBR (batch + no batch inventory). So far so good.
Now, users would like an additional display field for vendor.
I was thinking of getting the vendor (for batches) from tables mcha or mch1.
However, field lifnr in mcha is always blank, and only sometimes populated in mch1.
Hence these questions:
1) Is there an SAP standard inventory report that shows the vendor from which inventory was obtained?
2) Why would tables mcha / mch1 not always have the vendor field populated?
Sincerely,
Peter

Hi,
to print the alv header(for the REUSE_ALV_GRID_DISPLAY F.M.):
1.Activate the event into gt_events table
data: gt_events     TYPE slis_t_event
      g_top_of_page TYPE slis_formname VALUE 'TOP_OF_PAGE'
      ls_event      TYPE slis_alv_event
CALL FUNCTION 'REUSE_ALV_EVENTS_GET'
    EXPORTING
      i_list_type = 0
    IMPORTING
      et_events   = gt_events.
  READ TABLE gt_events WITH KEY name = g_top_of_page INTO ls_event.
  IF sy-subrc = 0.
    MOVE g_top_of_page TO ls_event-form.
    APPEND ls_event TO gt_events.
  ENDIF.
2. Is the step that you have implemented.
3. Define the form called TOP_OF_PAGE:
FORM top_of_page.
  CALL FUNCTION 'REUSE_ALV_COMMENTARY_WRITE'
       EXPORTING
          i_logo             = 'HTMLCNTL_TESTHTM2_SAPLOGO'
          i_logo             = 'ENJOYSAP_LOGO'
            it_list_commentary = gt_list_top_of_page. -> this is the i.t. where you have completed the data that must be written on the alv header.
Hope this help you,
