Haresh,
Make sure you check for the non-empty condition for ITAB before using FOR ALL ENTRIES IN option.
if ITAB[] IS NOT INITIAL.
ENDIF.
Always check for this condition , whether the driver table is having records, else,, you will end up with irrelavent records, in which you are not intrested in.
Thanks

How to Validate Multiple email address in spry?

How to validate multiple email address in spry framework?
Spry validate text field can validate one email address only,
if I the text field is for multiple emails, how can I validate
it?

Hello Jackson,
The Spry Textfield was designed to work with the normal work
flows that people currently use in most of the forms on the web. We
tried to prevent any email injection method in the forms therefore
the validation was designed to stop any multiple email insertion.
In case you want to insert multiple emails you'll have to
disable the default email validation and create your own validation
function, more flexible. You can see a
sample
we did for the custom validation trying to validate a password
strength and confirm the password.

How to validate the fields and how to display the error messagein presenta

Hi,
I am new to OBPM 10g, pls tell me how to validate the fields in a presentation.
for example if we take login presentation if user enters his user name and password wrongle and submit the form. Then we need to display error message right side of the each field i.e user name and passowrd is wrong and try again.
Regards
jaya
Edited by: 12345 on Aug 12, 2010 10:38 PM

Hi Jaya,
You can initially set the validation for empty values.. that is when the user dint enters any value and clicks on submit.
for these vadliations you need to write a method and call it on submit button click!!
secondly, you can validate for the format if required.
thirdly, you can validate against a database for the credentials. For this you need to fetch list of usernames from database and search for user entered value in that list.
Optimal query would be : if user name not null, query for pwd of the entered user name from database or file storage. if you dont get any value for pwd of given username, its incorrect user name. if you get some pwd value for username, then check against the one user entered in pwd field..
Write all this logic in a method and call on submit button click event of the login form!!

How to validate: only characters

Hi
I need to validate a textfield that can only contain
characters (doesn't mather what case and how many). How do I do
that?
Thanks

Hi walkerm,
Spry doesn't have provide an "alphabeticCharacters"
validation, but you could use in this case a custom validation
function that you will write yourself.
function myValidation(){
//do your validation here
var textfield1 = new
Spry.Widget.ValidationTextField("textfield1", "custom",
{validation: myValidation});
Please check the 8th sample on
this
page on Adobe Labs.

How to validate blank space ?

Hi All
I have a textfield i am showing alert if textfield is empty by using isNull and undefined way but how check if user give empty space ?
Thanks in advance !!!
Regards,
Ganesh

This is how to remove all blank spaces in a string:
Create a function in an object script, e.g.:
Script Object Name: myObject
Method Name : function trim(string)
function trim(str){
     return str.replace(/^\s+|\s+$/g, '');
//this function above return the string by replacing blank space by nothing (empty string or null string)
//it only replace if the field is empty, if there is no chars inside
//Show the output value after calling the method
TextField21.rawValue = myObject.trim(TextField21.rawValue);
//Here is a lil proto to see if it works
if (TextField21.rawValue == null){
          xfa.host.messageBox("Null");
} else{
          xfa.host.messageBox("Blank");

If Textfield is empty then deactive a button

Hello,
I have a Textfield and a Button with a Trigger. The Trigger like this code:
DECLARE
eingabe2 VARCHAR2(20);
BEGIN
eingabe2 := :eingabe;
IF eingabe2 = '' THEN :eingabe := 3;
END IF;
END;
I need a Trigger that the Button deactive, when the Textfield is empty.
Can someone Help me?
The Variable "eingabe" is the name of my Textfield.
Greetings

@Dipin ojha
Thank you, it works!
But i have found an other problem. ;-)
How can i change it, that the button ist so long deaktiv
till i write something in the Textfield ?
Because i have an "OK" button and i want, that the button is
active if something is writing in the textfield.
Hi,
wie man ein trigger direkt macht, wei_ ich.
Ich mvchte es gerade jetzt so haben, dass der Button erst
aktiv wird, wenn der User etwas in das Textfeld eingetragen hat,
weil ist ja blvd wenn man OK klicken kann, aber dann nix im textfeld steht.
Ps: Hast Du ICQ?

How to validate the dates in the table control ?

How to validate the dates in the table control ?
Can I write like this ?
LOOP AT it_tab .
CHAIN.
FIELD : it_tab-strtdat,it_tab-enddat.
module date_validation.
ENDCHAIN.
ENDLOOP.
Module Date_validation.
ranges : vdat type sy-datum.
vdat-sign = 'I'.
VDAT-LOW = it_tab-STRTDAT.
VDAT-HIGH = it_tab-ENDDAT.
VDAT-OPTION = 'BT'.
APPEND VDAT.
WHAT CODE I have to write here to validate ?
and If I write like this How can we know which is the current row being add ?
It loops total internal table ..?
Bye,
Muttu.

Hi,
I think there is no need to put chain endchain.
To do validation you have to write module in PAI which does required validations.

How to validate material status in physical Inv Doc creation using MI01

Hi Experts,
I would like to know how to validate material status while creating physical inventory document using MI01 transaction.
I tried to figure out a suitable BADI and customer exits ,but it didnt work out well.
Kindly share your thoughts on how this can be achieved.
Regards,
Mohammed Aslam Rasheed

Do you really create your inventory documents with this MI01 transaction manually by entering material for material?
The real transaction for physical inventory is MI31. How do you want SAP to react if hundreds of materials are selected and inventory documents are created in a batch process?
SAP takes care about the material status in MI04 and MI07 transactions.
I am not aware of any exit for MI01 maintenance, you may consider Explicit and Implicit Enhancement Options
