Check mandatory fields of view in ViewContainer

Hi Experts!
I created a view (main view) which containes a ViewContainer UI element. After a click on the main view I want to check the mandatory fields (with method check_mandatory_fields onview). But therefore I need the reference to the view controller which is embedded in the ViewContainer element. How can I solve this???
Thanks!

Hi
This is how I achieved it:
In DoINIT of the view which is embedded inside view container UI element I got the reference of view controller and stored it as a component controller public attribute
wd_comp_controller->mo_api_controller = wd_this->wd_get_api( ).
Here mo_api_conroller is a comp controller public attr of type ref to if_wd_view_controller.
Now you can call your method like this in the main view
cl_wd_dynamic_tool=>check_mandatory_attr_on_view(
    EXPORTING view_controller = wd_comp_controller->MO_API_CONTROLLER
              display_messages = abap_true
    IMPORTING messages = lt_messages
Hope this helps.

Strange problem while checking Mandatory fields

Hi ,
I am checking mandatory fields with the method following method.
CL_WD_DYNAMIC_TOOL=>CHECK_MANDATORY_ATTR_ON_VIEW( VIEW_CONTROLLER = my_controller ).
It was working fine for mandatory fields and also showing one extra input field which is not mandatory with red border .
Please tell me how to avoid this and What could be the problem.
Thanks and Best Regards,
Vijay

Hi Vijay,
            the extra vield thats showing in re d will be a field that doesnt support blank entry. try commenting the method thats calling CL_WD_DYNAMIC_TOOL.
            CL_WD_DYNAMIC_TOOL=>CHECK_MANDATORY_ATTR_ON_VIEW will check only mandatory fields.. thats for sure.
   the error message thats showing on the optional fild is coming from some standard check

Check mandatory fields before saving

Hello,
In my Z-program, how can I check all mandatory fields in a dynpro before saving?
Is there any function to do that?
Thanks!!!

Hi alberto,
1. If the fields are mandatory (as set in the field attributes while designing the screen),
2. then we don't have to write any additional logic for the same.
The system will AUTOMATICALLY check for it, and issue appropriate message.

Check Mandatory Fields (Dynamic Programming)

Hi All,
I am currently generating UI elements dynamically. I have few elements in these dynamically generated elements which are mandatory. Does anyone has information about how to programmatically check whether the entries have been made before the user is allowed to proceed to the next step? I have maintained the state property of the InputField and the webdynpro application doesnot automatically checks for the entries.
Any help will be greatly appreciated.
Thanks and regards,
Hemanth

Hi Hemanth,
there are at least two ways to do this:
1. Define some simple types in the local dictionary with minLength > 0 and use this simple types as the property types of the context attributes. If you bind the UI elements to this context attributes, the WD runtime will do the checks automatically.
2. Check the contents of the UI elements with required input manually (by checking the contents of the bound context attributes). Use the report(Invalid)ContextAttribute... methods of the <a href="https://media.sdn.sap.com/html/submitted_docs/60_sp2_javadocs/webdynpro/com/sap/tc/webdynpro/progmodel/api/IWDMessageManager.html">Message Manager API</a> to report missing data.
Hope that helps.
Regards
Stefan
PS: The state property is just a visual indicator for required/not required fields and doesn't trigger any automatic validation.

FPM - Check Mandatory Fields

Hi,
Could you please let me know, how can I do the required fields check in FPM?
I can do this requirement in a simple webdynpro application as below:
lo_view_controller = wd_this->wd_get_api( ).
cl_wd_dynamic_tool=>check_mandatory_attr_on_view(
EXPORTING view_controller = lo_view_controller
IMPORTING messages = lt_messages ).
CHECK lt_messages[] IS INITIAL.
Please let me know how can I do the same in FPM?
Thanks,
Vijay.

There is really no guideline about that. You have decided to go for Dynamic UI elements and you have to find a way to validate them that is the price you would pay for doing things in Dynamic programming. You might have to rely on the looping of your UI elements and see if it is state is mandatory and go for validation in a dynamic way. Requires lots of programming and understanding of UI hierarchy.

Mandatory input field in View

Hi All,
Mandatory input field in group
In my web dynpro application i have marked the input field "required" and in output it shows with red asterisks...
In my view i have 2 group elements with different fields. I am using method *check_mandatory_attr_on_view* to get mandatory fields in view, its not returning all mandatory fields in view. its just returning mandatory fields in first group.
Has any one faced this kind of issue before? Is there anything additional to be done?
Thanks
Rajesh Yadla

Depending on which NetWeaver SPS your are,
there are some errors in this method,
so better use the other method (CHECK_MANDATORY_ATTRIBUTES).
This seems to work well.
Check also SAP Notes:

Mandatory field on Service Call

Hi Expert,
I would like to make certain fields mandatory on a Service Call. (When Status Closed, a UDF I have added must be populated, if not block the user)
Will I be able to use transaction notifications? If this is the case, would you perhaps have some sample code that will guide me in the process?
Thanks in advance,
Adriaan

Hi Adriaan,
Use the Validate Item event of the Form_Data_Add and Form_Data_Update event's check mandatory fields.

Regards,
murthy.
Edited by: Murthy Ganti on Jul 13, 2009 2:31 PM

Hi,
Firstly goto view->select the element that you want to make mandatory and set the State property to required.
Secondly place the below code in the WDDOBEFOREACTION
DATA: l_view_controller TYPE REF TO if_wd_view_controller.
* Get view controller
l_view_controller = wd_this->wd_get_api( ).
* Check for mandatory attribute
cl_wd_dynamic_tool=>check_mandatory_attr_on_view(
EXPORTING view_controller = l_view_controller
display_messages = abap_true

Removing mandatory field checks

Hi all
We are working on ESS/MSS packages customization and we have a requirement where in we need to make a mandatory field in one of the screens, non-mandatory e.g. zip code in address information. I have the Webdynpro code of mentioned screen in my NWDS. Any pointers are welcome.
with thanks
amit

Hi amit,
The state of a webdynpro element can be set using
void setState(WDState value) in the implementation of your view.
Check the
IWDAbstractInputField
in
<a href="https://help.sap.com/javadocs/NW04S/current/wd/index.html">WDAPI</a>
Attributes available
static WDState NORMAL
The normal state of a UI element.
static WDState REQUIRED
Indicates that a UI element must provide a value for performing a certain action.

Check for mandatory fields while creating EP users using code .. :|

Hello All,
I have a code using which I can create user accounts/EP users on Portal, am working on EP6 SP9 & SP12.
My query:
1. From Portal's perspective -> While creating EP users, there are few mandatory fields like user-id, FirstName, LastName, Email-id and Password. If any of the above fields is null/empty, Portal would give us an error message.
2. From coding perspective -> Here, only the user-id is required. Even if I do not enter/fill any of the above mentioned mandatory fields (except user-id), user account is created.
In case wherein FirstName/LastName is not mentioned, Portal shows the userid in the Welcome Frame, i.e. Welcome <user-id>. Tried this by commenting the statements contains the methods related to setting/accepting FirstNme and LastName of user.
I want to know if this is all rite?
If no, then please guide me as to how can I set mandatory fields in my code.
Awaiting Reply.
Thanks and Warm Regards,
Ritu R Hunjan

Hi Ritu,
>>please guide me as to how can I set mandatory fields in my code??
In ur jsp file or in the controls code add the following attribute
<hbj:label id="userIdLabel"
 text="User ID"
 labelFor="userIdInput"
 design="HEADER3"
 required="true"/>
and to check the mandatory entry for that field do this in the submit button
<hbj:button id="insert"
 text="Submit"
 design="emphasized"
 onClick="save"
 onClientClick="if(!isMandatory()) htmlbevent.cancelSubmit=true;;"/>
and in the javascript write the client validation code.
Hope this helps.

Check duplicate data entry in multi record block,which is a mandatory field

Dear all,
I have a situation where i have to check duplicate data entry(on a particular field,which is a mandatory field,i.e. it cannot be skipped by user without entering value) while data key-in in a Multi Record block.
As for reference I have used a logic,such as
1>In a When-Validate-Record trigger of that block I am assigning the value of that current item in Table type variable(collection type)
as this trigger fire every time as soon as i leave that record,so its assigning the value of that current time.And this process continues
then
2>In a When-Validate-Item trigger of that corresponding item(i.e. the trigger is at item level) has been written,where it compares the value of that current item and the value stored in Table type variable(collection type) of When-Validate-Record trigger.If the current item value is matched with any value stored in Table type variable I am showing a message of ('Duplicate Record') following by raise_form_trigger failure
This code is working fine for checking duplicate value of that multi record field
The problem is that,if user enter the value in that field,and then goes to next field,enter value to that field and then press 'Enter Query 'icon,the bolth Validate trigger fires.As result first when-validate record fires,which stores that value,and then when-validate-item fires,as a result it shows duplicate record message
Please give me a meaningful logic or code for solving this problem
Any other logic to solve this problem is also welcome

@Ammad Ahmed
first of all thanks .your logic worked,but still i have some little bit of problem,
now the requirement is a master detail form where both master and detail is multirecord ,where detail cannot have duplicate record,
such as..........
MASTER:--
A code
A1
A2
DETAIL:--
D code
d1
d2 <-valid as for master A1 , detail d1 ,d2 are not duplicate
d2 <--invalid as as for master A1 , detail d2 ,d2 are duplicate
validation rule: A Code –D Code combination is unique. The system will stop users from entering duplicate D Code for a A Code. Appropriate error message will be displayed.*
actually i am facing a typical problem,the same logic i have been applied in detail section ,its working fine when i am inserting new records.problem starts when i query,after query in ' a ' field say 2 records (i.e. which has been earlier saved) has been pasted,now if i insert a new record with the value exactly same with the already present value in the screen(i.e. value populated after query) its not showing duplicate.................could u tell me the reason?and help me out...............its urgent plzzzzzzzzz

Mandatory check on fields

Hi,
We have upgraded to CRM 7.0.
We have placed mandatory check on some fields in service tickets in UI. But the mandatory checks work in a wired way.
For example if I am in Interaction History work center where we have marked partner as mandatory field for search.
But If I do not perform any search and try to navigate to the other workcenter the system throws a mandatory check error.
Is this the standard behaviour in CRM 7.0.
Regards
Yogesh

Hi Gopi,
Why do you want to perform the checks on Serverside event....why not on client side event ie. onClientClick ?
For validations on serevr side event onClick you can use the method
Data: it_fields type it_fields TYPE tihttpnvp .
CALL METHOD request->get_form_fields
CHANGING
fields = it_fields.
This table it_fields contains values of all the elements in the form.
Hope it helps.

Anubhav.

I have customized a COPA characteristic group in KEPA transaction entering the product as a mandatory characteristic.
Then I have posted a document in FBD9 taking a reference document that does nor have filled the product and the system does not show an error and the document is posted without the mandatory field.
How could I solve this problem?
Thank you very much
Regards

Hi
Did you assign this char group in KE4G against your Busn Trans or in KEVG2 against record type B?
If yes, and still it is not reading it, then refer note 115500.. you may need to apply this note
