Hi Anil

Your requirement seems to be confusing...

Do you need to validate Sales Order Number and Plant for the range of customers or Sales Order Number and Plant individually???

I want to validate sales order no and plant individually.Plant nos are from 1-10.

Customer numbers are from 100-1000.

How can i do this?

Hi,

IS it select-options?

data: c_min like kna1-kunnr default '00000100',

c_max like kna1-kunnr default '00001000'.

SELECT-OPTIONS SO_kunnr FOR kna1-kunnr

DEFAULT c_min TO c_max

OPTION BT SIGN I.

Does this help??

We should not hard code that.If the customers who are in between 150-200 are not having any orders ,will the code work properly?

regards and thanks in advance,

Make sure that u are validating against the header table.

say eg if u wnat t validate matnr in marc, then do as below.

SELECT-OPTIONS: s_matnr FOR  marc-matnr.                  "Material No
AT SELECTION-SCREEN.

*Validate material no details
  PERFORM validate_matno.
FORM validate_matno.
DATA: v_matnr LIEK mara-matnr.
  SELECT SINGLE matnr INTO v_matnr
         FROM <b>mara</b>
         WHERE matnr IN s_matnr.

  IF sy-subrc NE 0.
    MESSAGE i128.
    LEAVE LIST-PROCESSING.
  ENDIF.

ENDFORM.

Dont select from marc.

Hope this is clear.

Anil,

If your selection-screen has a parameter of Plant and Select option of VBELN. You can validate these fields only as shown above, why do you bother about Customer Nos.
