Selection-screen functionality

Question

Hi,
I have 2 questions regarding selection-screens:
1. I have 2 select-options like this in my selection-screen:
Matnr:  s_matnr
Vendor: s_lifnr
How can I make a check that if Matnr is filled then Vendor has to be filled as well and vice versa ?
2. I want to take the interval of data from a select-option and create the records in an internal table:
example
Contract no:  From 45000000 To 45000025
All the records that are contracts (document cat. = K) from that interval have to be appended to an internal table.

  MOVE 'Material-Plant' TO tit.
AT SELECTION-SCREEN ON p_matnr.

    SELECT SINGLE matnr
      INTO lw_matnr
      FROM mara
     WHERE matnr EQ p_matnr.
    IF sy-subrc NE 0.
      MESSAGE e000(PP) WITH p_matnr.
    ENDIF.

ENDFORM.                    " validate_material
FORM validate_plant .
  DATA

  IF p_werks IS NOT INITIAL.
    SELECT SINGLE werks
      INTO lw_werks
      FROM t001w
     WHERE werks EQ p_werks.
    IF sy-subrc NE 0.
      MESSAGE e272(61) WITH p_werks.

  AND p_werks IS NOT INITIAL.
    SELECT SINGLE matnr
      INTO lw_matnr
      FROM marc
     WHERE werks EQ p_werks
       AND matnr EQ p_matnr.

      MESSAGE e707(12) WITH p_matnr p_werks.

ENDFORM.                    " validate_material_plant_comb
I have done it with parameters You just convert into select options.
