If you want to call the SM30 from a program you can use CALL TRANSACTION but there is a simpler way.

SAP provides some functions to make this easier:

• VIEW_MAINTENANCE_CALL
• VIEW_MAINTENANCE_SINGLE_ENTRY
• VIEWCLUSTER_MAINTENANCE_CALL (for SM34)

Here’s an example:

DATA(v_t001w) = VALUE v_t001w(
  mandt = sy-mandt
  werks = '0001' ).

CALL FUNCTION 'VIEW_MAINTENANCE_SINGLE_ENTRY'.
  EXPORTING
    action = 'SHOW'.
    view_name = 'V_T001W'
  CHANGING
    entry = v_t001w.

Nice?

Thank you Luís Rocha for the tip.
