You double-click on a cell to navigate to transaction MSC3N.

 

  SET PARAMETER ID 'MAT' FIELD fu_matnr.
  SET PARAMETER ID 'CHA' FIELD fu_charg.
  SET PARAMETER ID 'WRK' FIELD fu_werks.
  SET PARAMETER ID 'LAG' FIELD l_empty_lgort.
  CALL TRANSACTION 'MSC3N' WITH AUTHORITY-CHECK
                           AND SKIP FIRST SCREEN.

Default Tab displayed is the first one.

 

You want to arrive to a specific tab, not the default one (<=> 1st tab).

Add ABAP instruction before CALL TRANSACTION

  SET PARAMETER ID 'LAST_TAB_BATCH' FIELD '2300'."(+)

2300 is the screen number of tab "Classification" for example.

Screen possible values can be found  there (include LCHRGF04 ; FORM d2000_ok_code )

    CASE dynp_body.
      WHEN 2200.        ok_code = 'SNST'  ."Donnée de base 2
      WHEN 2300.        ok_code = 'CLAS'  ."Classification
      WHEN 2400.        ok_code = 'MATK'  ."Donnée article
      WHEN 2500.        ok_code = 'CHANGE'."Modif.
