you can just use a single select option statement:

tables: mkpf.

select-option: p_mblnr for mkpf-mblnr.

this will solve your issue.

Please reward the helpful entries.

Please see the sample program

AT SELECTION-SCREEN ON VALUE-REQUEST FOR S_REVNR-LOW.

  PERFORM GET_REVISION_NUMBER USING 'S_REVNR-LOW' 'REVNR'.



FORM GET_REVISION_NUMBER USING
              VALUE(FIELD_NAME) LIKE  HELP_INFO-DYNPROFLD
              VALUE(FIELD_TYPE) LIKE  DFIES-FIELDNAME.

  DATA: I_RETURN TYPE DDSHRETVAL OCCURS 0 WITH HEADER LINE.

  DATA: BEGIN OF I_REV OCCURS 0,
           REVNR LIKE T352R-REVNR,
        END   OF I_REV.
  DATA: V_S TYPE C VALUE 'S'.
  IF I_REV[] IS INITIAL.
    SELECT REVNR
           INTO TABLE I_REV
           FROM T352R.
    SORT I_REV BY REVNR.
    DELETE ADJACENT DUPLICATES FROM I_REV COMPARING REVNR.
  ENDIF.

  CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'
    EXPORTING
      RETFIELD        = FIELD_TYPE
      DYNPPROG        = SY-REPID
      DYNPNR          = SY-DYNNR
      DYNPROFIELD     = FIELD_NAME
      VALUE_ORG       = V_S
    TABLES
      VALUE_TAB       = I_REV
      RETURN_TAB      = I_RETURN
    EXCEPTIONS
      PARAMETER_ERROR = 1
      NO_VALUES_FOUND = 2
      OTHERS          = 3.

You have issues at 2 places:

1) Change the names in internal table to table fieldnames.

data: begin of itab occurs 0,

mblnr like mkpf-mblnr,

mjahr like mkpf-mjahr,

end of itab

2) In select statement you are selecting only one MBLNR which is entered on screen. so if screen parameter is empty, it will not display anything.

You should write something like:

select mblnr mjahr from mkpf into table itab upto 200 rows.

or you can define it a select option and allow user to write a pattern in the select option field and then you can write select like:

select mblnr mjahr from mkpf into table itab where mblnr in s_mblnr upto 200 rows.

or you can create a search help and attach it to the parameter
