hi,

SELECT SINGLE KUNNR FROM KNA1 INTO LW_KUNNR

WHERE KUNNR IN SKUNNR.

Is not initial means there are some records for the condition u have given and

= 'X' means u r entering some value for that field.

Hi

write as below

FORM VALIDATE_KUNNR.

DATA:LW_KUNNR TYPE KNA1-KUNNR.

<b>IF NOT SKUNNR[] IS INITIAL.</b>

SELECT SINGLE KUNNR <b>FROM</b> KNA1 INTO LW_KUNNR

WHERE KUNNR IN SKUNNR.

IF SY-SUBRC NE 0.

MESSAGE E000(0) WITH 'INVALID CUSTOMER'.

ELSE W_INPUT = 'X'.

hI,

iAM GETTING fIELD W_INPUT IS UNKNOWN.

[former_member189059]

check if W_INPUT is being used anywhere else in the program

if it is then declare it as

data: W_INPUT.

if it is not being used then simply delete the 'else w_input = 'X'.' line

Hi Rams,

I think you should use "IF SKUNNR[] IS NOT INITIAL" instead of "IF SKUNNR IS NOT INITIAL".

I hope it helps. Best regards,

Hi,

FORM VALIDATE_KUNNR.

DATA:

LW_KUNNR TYPE KNA1-KUNNR.

IF SKUNNR IS NOT INITIAL.

SELECT SINGLE KUNNR ON KNA1 INTO LW_KUNNR

WHERE KUNNR IN SKUNNR.

IF SY-SUBRC NE 0.

MESSAGE E000(0) WITH 'INVALID CUSTOMER'.

ELSE W_INPUT = 'X'.

ENDIF.

ELSE.

MESSAGE E000(0) WITH 'ENTER CUSTOMER NUMBER'.

ENDIF.

ENDFORM.

In the form the the error might be because you are using a SELECT OPTIONS parameter in the where condition but the select options allows you to enter a range of values.In that case the select single statement may not work as one place you want to select single and at the other you are using a select options.

Also the initial check is useful as it prevents unnecessary database access.

The select-options is just like an internal table.If it is empty and you do a select then unnecessary database access will take place which will reduce performance.

So an initial check is done.

Hope it will be useful.

Thanks,

Sandeep.

checking skunnr will refer to a structure (or header line or work area) with that name

to refer to a table of the name skunnr use skunnr[]

[gopi_narendra]

You are trying to get a single value from KNA1 by validating against a select-options.

Select-Options is nothing but an internal table. So you cant do it that way.

And first of all change your declaration of selection screen.

* S E L E C T I O N S C R E E N
SELECTION-SCREEN BEGIN OF BLOCK B1 WITH FRAME TITLE TEXT-001.
SELECT-OPTIONS: SKUNNR FOR VBAK-KUNNR.
SELECTION-SCREEN END OF BLOCK B1.
SELECTION-SCREEN BEGIN OF BLOCK B2 WITH FRAME TITLE TEXT-002.
SELECT-OPTIONS: SVBELN FOR VBAK-VBELN MODIF ID M1,
                              SAUDAT FOR VBAK-AUDAT MODIF ID M1.
SELECTION-SCREEN END OF BLOCK B2.

STVBAK is an internal table and you are using it in the declaration, which cant be used.
