Assigning a value to screen field

Hi,
Anybody knows how to assign a value to a field in a standard transaction without using parameter ID.
Pionts will be awarded.
Thanks,
lakshmi.

Thank you so much Rich & eswar. here is my problem.
Actually I am updating this field based on the contract starts date and material group using one user exit.But this field is geting updated whenever there is a change to this field.it is not geting updated in other cases that is "it is geting updated if you are changing the contents of the filed or giving a new value".
But I want this field updated all the times.
So I thought I will assign a dummy value to this filed before I update it.For this We need a parameter id. but it is not there. So I am searching for other solution.
Can you please help me.
Regards,
Lakshmi

Assigning a value to a field-symbol (workarea of type any)

Dear forumers,
I'm having a bit of difficulty in assigning a value to a field-symbol (it should be treated as a workarea of type any), but I'm given a syntax error instead:-
The data object "<LFS_WORKAREA>" has no structure and therefore no component called "LFMON".
What could have gone wrong and how may I resolve this (I must have missed something out)? I will still need <LFS_WORKAREA> to be defined as TYPE ANY.
Please help. I'd appreciate any inputs at all. Thanks.

Holding the value in screen-field

Dear All,
I m facing the problem ,while i m putting the value in screen-field and then pressing enter,
value in that screen-field is becoming null automatically.
wht shld i do for holding the value even after PAI.
Thanks in advance.

Hi,
You should define a corresponding variable for that screen field in your program.
data: my_input_field type ... "same name and type as the one used in screen for field
so when you enter data to that field and press ENTER, the data will be transported to that variable and in PAI you have its value there.

How to populate the calculated values in Custom screen?
Where we wrote the code to populate the calculated values in custom screen?
You have any idea please guide me
Thanks & Regards,

As your screen fields should be global variables in SAPLXQQM, you may initialize them by implementing function module EXIT_SAPMIWO0_008 which also belongs to SAPLXQQM (Customer Exit: Transfer Notification Data to User Screen)

Process on value request in Dialog screen based on value of screen field

Hello Gurus,
I have a check box on a dialog screen. If the checkbox is checked, based on that I want the other field on the same dialog screen to follow logic for F4 dropdown.
Now I know if I want to write this, I have to write this in Process on value-request. But how do I get the value of the check box checked or not on the same screen in Process on value-request.
If it had been a simple selection screen I would have defined the check box as
Parameter: v_checkbox as checkbox user-command uc1.
But how do I handle above situation in dialog screen case ?
Please help.
Regards,
Jainam.
Edited by: Jainam Shah on Sep 29, 2009 6:19 PM

Hi Shah,
You have the addition for MODULE statement as ON INPUT.
Eg : FIELD <screen field> MODULE <module> ON INPUT.
You can give the check box field name in the above statement.
If you want to find as soon as the check box is checked, you can find it here.
Or else, in the addition ON REQUEST
you can see for the check box field value whether it is checked or not.
Thanks,

Not allows to assign default value to input field using values in datastore

Hi Masters,
Consider that I have one input field in a form. I should assign default value to it. I should assign to it, the value which i have stored in a datastore. When i run the application, if i give default value as 123 ,then it is working fine i.e., it is showing 123 in the textfield in form , but if i give the default value as STORE@ProductId, then it is not displaying that value in the form.
Please help me out.
Thanks & Regards,
Kaushik Sreeram

Hi,
i faced this problem and here's what i concluded:
There's no way you can set default value for input field dynamicly, since the default value of input control is caculated only once (i think on initializing of the iView). The input control and the data store are initialized at the same time, STORE@productID is empty that time...
If you don't need to recieve value through the input field you're trying to initialize, but just to display the value from the store - I suggest you try using another control - Expression Box. It's value is calculated continiously, just like the Label's, and you can refere to it later.

Transfer Rule Routine: Assign Date Value into Blank Field

Can anyone help me with regards to writing some ABAP code in a transfer rule so that I can assign "99991231" value into a date characteristics if it is blank?
Many thanks for advance.

I would like to check if the value of EXPIRYDATE is blank in data source. If its value is blank, assign '99991231' to it. Otherwise, it will get the value of EXPIRYDATE in transfer rule. I have rewritten the routine as follows. But there is no effects on the result.
if TRAN_STRUCTURE-EXPIRYDATE IS INITIAL.
RESULT = '99991231'.
else.
RESULT = TRAN_STRUCTURE-EXPIRYDATE.
endif.
Many thanks in advance.

Values in Screen Field

Hi,
There is a screen (3140 function group CRM_TSRV_UI) which has got field one with 'CRMT_3140_TSRV_UI-OBJECTIVE' which is assigned to data element CRMT_OBJECTIVE. This data element 'CRMT_OBJECTIVE' has the length of 3 character and so does the domain 'CRM_OBJECTIVE' which is assigned to it.
In the domain there is a value table 'CRMC_ACT_OBJ' assigned to it which again has got the primary field 'objective' with length 3.
The table structure 'CRMC_ACT_OBJ' contains only two fields mandt and objective, but when you see the table contents it shows 3 fields, with one additional field 'description' coming from the another table which is maintained as a text table CRMC_ACT_OBJ_T
When I call this field on the screen 3140 (as a list box) it shows me the Description instead of Key, even when the length of the field is 3 characters.
what can be the explanation on how it is picking up the description and also not giving any error when the field length is 3 characters.
I have to restrict the value in this list and for that I tried using POV event (process on value-request) but when I try to input the description or any value with length more then 3 characters I got a error message.
Suggestions..!
Thanks in adv.
/Manik

Hi Manik,
This is standard SAP functionality. It is picking up the description from the text table i.e. CRMC_ACT_OBJ_T for the objective code in the table CRMC_ACT_OBJ.
SAP has internally linked both the tables to do so. Whenever you are refering to this field anywhere in your program just use code instead of the description and you won't get any error. SAP takes care of matching the code with the corresponiding description. You can check out this mapping in the SPRO transaction.

Providing value to screen field during f4.

hi all,
am having selection screen as follows

Hi,
you must use DYNP_VALUES_UPDATE or RS_SELECTIONSCREEN_UPDATE function module (this latter is mandatory only for select-options). See forum for more information.

Not able to get the values from screen field?

hello
i am using MIRO and there is a screen name withholding tax and from there i want to retreive the withholding tax code before saving so that i can do some validations on it but how can i retrieve the values.
when i press f1 there it shows structure not the table and structure contains no value so please help me in this so that i can retreive that value during run time
thank you

Hi Vikas,
you can use this badi MRM_WT_SPLIT_UPDATE, the method will be WHTAX_SPLIT_UPDATE
in this badi please see the importing and exporting parameters, you will get the values of withholding tax code as TE_RBWS in export parameters.
Please search in google or SCN you will get how to use it.

How to assign the Value to the Particular field-Text field

Hi all,
My requirement is to call the Web service with input from the ADF page.
Steps I have done:
1. I have created a Web service data control based on the WSDL file.
2. Just drag and drop the Process, It is automatically created the form with the Input fields and then the Process button
3. When I entered the values and then process button it will pass the values corretly.the web service is invoked correctly with the values entered.
4. But when I try to assign the value from the some other field that is not working.
I am assigning the Value to the field by go to the properties of the Particular field value =”CREATE”
When I do like this that value is showing in the screen. But it will not pass the value to the web service.
I think the value is only displaying in the screen. Not stored at bindings level. Kindly guide me in this.
Thanks in Advance
C.Karukkuvel

If you want to have the value that is returned displayed in a field that has binding to another item and not the WS result item then the way to do this would be to override the method that is invoked with the button that calls the web service - you then take the result and assign it to the item you want.
See the way it is done here:
http://blogs.oracle.com/shay/2009/07/java_class_data_control_and_ad.html
While this sample uses a simple method it would be basically the same for a Web service.

Display value in custom field selection of standard field

Hi,
I want to display the country value based on the Account selection, that is the country associated with the selected Account.
I created Contact extension BO and added country field with data type CountryCode. Account is a standard field.
I am able to fetch country value but assigning the value to Country field can be done in only BeforeSave.absl
I have also provided validation for this country field.
Issue here is:
First Validation-OnSave.absl gets called and then BeforeSave.absl.
I want the country value to be displayed once the user selects Account.
Regards,
Vijaya Chavan

Hi Vinod,
I got the issue.
AfterModify.absl gets called when the Contact Quick Create screen gets loaded and not after selecting the Account field value.
So I tried geting the value directly from the following path without firing a query in BeforeSave.absl.
this.CurrentDefaultIsContactPersonFor.BusinessPartnerRelationship.FirstBusinessPartner.AddressInformation.GetFirst().AddressSnapshot.PostalAddress.GetFirst().CountryCode;
But BeforeSave.absl gets called when I click on "Save". I wanted the value to be displayed soon after the Account Value is selected.

How to set default value to input field dynamically

Hello Experts,
I am using adobe forms inside Webdynpro Java.
Adobe form is having few input fields where at run time i want to assign default value to those fields.
How can i do it ?
Thanks in advance,
Vinay
Edited by: VINAY on Feb 24, 2011 6:39 AM

Hi Mate,
Just set the value to the webdynpro context fields on view init.
if its like that will override the values entered by use on the form.
just check if the default value is equall to the field value if yes leave it, if not dont touch that field.
does this make sense...?

Default values for Screen Fileds

Hi All
By default, if a user doesnt give a value for a particular field, it will have the Default Value of the particular type.But i want it to retain a Null Value in such case. Is it possible.
I have a numeric field in my screen. I need ot trigger a error message if the user doesnt enter any value..
And to accept if ihe enters 0.
BUt even if the user doesnt give any value, the screen field gets 0.
Is there any way to do this

You might want to check out using the "on request" on some modules in the screen flow to determine if the user has keyed something in... from [Conditional Module Calls|http://help.sap.com/saphelp_46c/helpdata/EN/9f/dbabbd35c111d1829f0000e829fbfe/content.htm] :
ON REQUEST
The module <mod> is only called if the user has entered something in the field. This includes cases when the user overwrites an existing value with the same value, or explicitly enters the initial value.

OperationBinding operationBinding = bindings.getOperationBinding("Commit");

Object result = operationBinding.execute();
if (!operationBinding.getErrors().isEmpty()) {
return null;
return null;
please do guide. what to do.
Regards
M Niaz

Thanks,
I know, that's why i am try to put this on save button instead on any other.
But this is not an issue whether to use sequence or max()+1. I can use sequence instead but even then i have to get the nextvalue on form before commit.
and i have to put that on commit button.
Commit but try to commit the form before getting anything from DB.
