DATA: tf_cust_id(10),

tf_cust_region(3),

tf_cust_s_name(30),

tf_cust_l_name(50),

click_bt TYPE sy-ucomm,

count_cs(2).

&----

*& Module STATUS_0001 OUTPUT

MODULE status_0001 OUTPUT.

SET PF-STATUS 'xxxxxxxx'.
SET TITLEBAR 'xxx'.

if sy-subrc <> 0.
"leave to transaction 'ZFSLSCB'.
ENDIF.

ENDMODULE. " STATUS_0001 OUTPUT

IF click_bt = 'EXIT'.

LEAVE PROGRAM.

ENDIF.

IF click_bt = 'EAGAIN'.

LEAVE TO TRANSACTION 'ZFSLSCB'.

ENDIF.

CONDENSE tf_cust_id.

count_cs = STRLEN( tf_cust_id ).

IF count_cs = 0.

CLEAR: tf_cust_id,

SELECT SINGLE * FROM kna1 WHERE kunnr = tf_cust_id.

IF sy-subrc = 0.

CALL FUNCTION 'CONVERSION_EXIT_ALPHA_OUTPUT'

EXPORTING

input = tf_cust_id

IMPORTING

output = tf_cust_id.

tf_cust_region = kna1-regio.

tf_cust_s_name = kna1-sortl.

hi,

you have to define your fields in chain endchain in pai .


CHAIN.
 
 FIELDS: f1,f2...
 MODULE CHECK.
 
ENDCHAIN.

and you can do your checks in this module check.

Hi, thanks,

it is working but there is a problem for example I give it a customer id and it display the records in the fields but next time when I give a wrong customer no it display the message and field are enable but I want that when I enter the wrong customer no it clears out the records related to the previous customer mean display the error message and clear all the fields too.

Faisal

Hi,

In the module under chain end chain just clear the fields if input is wrong....

say


MODULE validation_9000 INPUT.
        clear : <your wrong field>.
        MESSAGE s398(00) WITH 'Please enter correct details'.
       

ENDMODULE.                 " VALIDATION_9000  INPUT
