Hi,

Declare the fields with their master tables after declaring those tables with TABLES statement.for few I will give the code, rest you practice.

You have to write this code in AT SELECTION-SCREEN event.

S_WERKS FOR T001W-WERKS,

S_KUNNR FOR KUNNR-KUNNR,

• Validation of Customer

clear kna1.

if not s_kunnr is initial.

select kunnr from kna1 up to 1 rows

into kna1-kunnr

where kunnr in s_kunnr.

endselect.

if sy-subrc ne 0.

message e014. " Invalid Customer Number

endif.

endif.

• Validation of Plant

clear t001w.

if not s_werks is initial.

select werks from t001w up to 1 rows

into t001w-werks

where werks in s_werks.

endselect.

if sy-subrc ne 0.

message e004. " Invalid Plant Number

endif.

endif.

Use the event AT SELECTION SCREE ON <Feild Name> for each selection screen element.

For each element perform the following checks.

1. Value has been entered

IF <Feild_name > is initial.

give error message.

endif.

2. Valid value is entered

Select single <feild>

from <table>

where <feild_t> = <feild_name>.

if sy-subrc = 0 .

• Give success message

else

• Give error message

endif.

Hope this helps

Here it is...

SELECT-OPTIONS sel_opt1 FOR field1.

SELECTION-SCREEN BEGIN OF BLOCK block1.

PARAMETERS: test1(10) TYPE c,

test2(10) TYPE c.

SELECTION-SCREEN END OF BLOCK block1.

AT SELECTION-SCREEN ON BLOCK block1.

MESSAGE i888 WITH 'AT SELECTION-SCREEN'

'ON BLOCK BLOCK1'.

Have a look at the demo program demo_selection_screen_events for more details.

Hi,

As u want to check whether '.' present before and after @, split w_str at @ into w_str1 and w_str2.

Then u can search for '.' in both w_str1 and w_str2.

Reward if it helps....

Hi Thanks. But i wnat to check like this:

str1 = ravi.babu

str2= gmail.com

i want to check whether '.' is there after 'u' in str1 and

'.' is there or not after 'm' in str2

How can i do this?

[Former Member]

Hii Ravi, according to your requirement.

Sample coding

IF NOT STR1 CA '%U.'.

MESSAGE.

ELSE.

MESSAGE.

ENDIF.

IF NOT STR2 CA '%M.'.

MESSAGE.

ELSE.

MESSAGE.

ENDIF.

but there is a problem that u have m in str2 twice. so instead of all these use the below sample code it will work.

IF NOT P_MAIL CP '%@%.com'.

MESSAGE

ENDIF.
