You will have to use this:
1. Change the macro following way:
DEFINE m_fieldcat.
  add 1 to ls_fieldcat-col_pos.
  ls_fieldcat-fieldname   = &1.
  ls_fieldcat-ref_tabname = &2.
  ls_fieldcat-fix_column = &3.
  ls_fieldcat-reptext_ddic = &4.    " << will repalce from the macro's argument
  append ls_fieldcat to lt_fieldcat.
END-OF-DEFINITION.
2. Call the macro like this.
m_fieldcat 'OBJECT' 'ITAB' 'X' 'Object'
  m_fieldcat 'OBJECT_NAME' 'ITAB' 'X'  'Oject Name'.
