Here is the workaround. The field _CB4 is a header in the table control
on screen 0300 of ZPMRMXX1. This peice of code needs to be executed
before the relevant screen is called. The first 2 functions is to read
and update the screen fields and the last one to generate the screen
before it is called.

Code:
DATA:
h_import LIKE d020s,
i_e_g LIKE d022s OCCURS 0 WITH HEADER LINE,
i_f_g LIKE d021s OCCURS 0 WITH HEADER LINE,
i_m_g LIKE d023s OCCURS 0 WITH HEADER LINE.

CALL FUNCTION 'RS_SCREEN_IMPORT'
     EXPORTING
          dynnr        = '0300'
          progname     = 'ZPMRMXX1'
          wanted_mode  = 'MODIFY'
     IMPORTING
          h_import     = h_import
     TABLES
          e_g          = i_e_g
          f_g          = i_f_g
          m_g          = i_m_g
     EXCEPTIONS
          not_executed = 1
          not_found    = 2
          OTHERS       = 3.

LOOP AT i_f_g.
  IF i_f_g-fnam = '_CB4'.
    i_f_g-stxt = 'ROB1'.
    MODIFY i_f_g.
  ENDIF.
ENDLOOP.

CALL FUNCTION 'RS_SCREEN_EXPORT'
     EXPORTING
          dynnr                 = '0300'
          h_export              = h_import
          progname              = 'ZPMRMXX1'
          dynpro_language       = sy-langu
          save_without_question = 'X'
          without_corr_insert   = 'X'
     TABLES
          e_g                   = i_e_g
          f_g                   = i_f_g
          m_g                   = i_m_g
     EXCEPTIONS
          canceled_by_user      = 1
          OTHERS                = 2.

CALL FUNCTION 'RS_SCRP_SERVICE'
     EXPORTING
          dynnr           = '0300'
          function        = 'GENER'
          progname        = 'ZPMRMXX1'
          suppress_checks = 'X'
     EXCEPTIONS
          illegal_value   = 1
          not_exists      = 2
          cancelled       = 3
          OTHERS          = 4.
