Hi Frnd,

Yes. It is possible to select from different db table dynamically usin gthe below code.

**variables for dynamic building
*DATA: wh_codn TYPE TABLE OF char72 WITH HEADER LINE,*
      *field TYPE TABLE OF char72 WITH HEADER LINE.*
DATA: d1 LIKE sy-datum,
      date1 LIKE sy-datum,
      date2 LIKE sy-datum.

**selection screen
PARAMETER       p_tab TYPE dd02l-tabname .
SELECT-OPTIONS  s_date FOR sy-datum NO-EXTENSION MODIF ID grp.
PARAMETER       p_fname1(5) TYPE c .
SELECT-OPTIONS       s_gjahr FOR MSEG-MJAHR NO-EXTENSION MODIF ID GP1 .
PARAMETER: p_sum RADIOBUTTON GROUP gid USER-COMMAND flag,
           p_det RADIOBUTTON GROUP gid.

START-OF-SELECTION.

**dynamic building.
    IF NOT s_date-low IS INITIAL AND NOT s_date-high IS INITIAL.
      CONCATENATE  p_fname1
                   'BETWEEN'
                   s_date-low
                   'AND'
                   s_date-high
                   INTO wh_codn
                   SEPARATED BY space.
      APPEND wh_codn.
      CLEAR wh_codn.
    ELSEIF s_date-high IS INITIAL.
      CONCATENATE  p_fname1
                   'EQ'
                   s_date-low
                   INTO wh_codn
                   SEPARATED BY space.
      APPEND wh_codn.
      CLEAR wh_codn.
    ENDIF.
**field name
    field = p_fname1.
    APPEND field.
**selection
    *SELECT (field) FROM (p_tab)*
             *INTO d1*
             *WHERE  (wh_codn) .*
      itab-date = d1.
      APPEND itab.
    ENDSELECT.

**sorting
    SORT itab.
**display of records
    WRITE :/ 'Number of records in', p_tab .
    SKIP.
    ULINE.
    LOOP AT itab.
      AT END OF date.
        WRITE:/ itab-date ,
                gv_count COLOR 4.
        CLEAR gv_count.
      ENDAT.
      gv_count = gv_count + 1.
    ENDLOOP.
    ULINE.

Yes it is possible.

If you search in SDN for key words dynamic select , you will get lots of sample codes.

hi,

If your query is about dynamically specifying the data base table during select statement then check out the following code snippet.

PARAMETERS:
P_TABLE(10) TYPE C.

DATA:
ITAB TYPE TABLE OF CHAR255.


SELECT  *
  INTO  TABLE ITAB
  FROM  (P_TABLE).

Thanks

Hi,

yes, You can search with key-word Dynamic Table,

data: begin of itab occurs 0.
      include structure mara.
data: end of itab.

SELECT matnr from (p_tab) into table itab.
