How to populate read only input field or text view form value help only

Hi experts,
I have one requirement to populate a read-only field or text view from value help.
User cant put any value there.value comes only from the value help.
For example,
when we read context using Code Wizard,we cant type any value there.value only comes from value help.
How to implement that functionality?
Please reply.
Thanks in advance,
Subhasis.

Yes it is possible.
1.Create a context Attribute and then bind this attribute to the Text view UI element.
2. read context attribute and then set value to the context attribute like this way.
DATA:
    elem_context1                        TYPE REF TO if_wd_context_element,
    stru_context1                        TYPE if_first=>element_context ,
    item_potxt                          LIKE stru_context-potxt.
get element via lead selection
elem_context1 = wd_context->get_element( ).
stru_context1-potxt = 'PO'.
elem_context1->set_attribute(
    VALUE = stru_context1
    name   = 'POTXT'
thanks

OVS on read-only input field

OVS will not allow me to change the value of a read-only input field. If the input field is set to read-only, the OVS selection table does not display an 'OK' button, only close.
Value cannot be copied (field is not editable)
I do not want the field to be editable on the screen, but only allow input via the selected row in the OVS. Any suggestions?
Edited by: Bob DeNuto on Jul 31, 2008 1:22 AM

Using Dictionary Search Help and OVS in this case will disable the Copy button and you don't have any control.
Use Freely Programmed Value Help, this will solve your problem

How to right align a read only numeric field in a panel form layout

Hi, does anyone know how to right align a read only numeric field in a panel form layout? I am using: Style Class = AFFieldNumberMarker, but it only seems to work if the field is disabled. Disabling the field gives it a difference appearance that does not look right on our forms. These are calculated fields, which cannot be modified, so read only is necessary.
I have looked online for some answers, and it seems that others are having similar issues.
I have tried different combinations for the properties, but so far I cannot get it to work.
Thanks

Search help unavailable in Read-only input field since EHP4

Dear Experts!
I have a problem with a Portal page since the deploy of the EHP4. The page has standard input fields with Search Helps. I needed to have the input field non-modifiable so the user would have to use the search help to get the proper information.
Prior to the EHP4 installation, I set the input field to Read Only in the WebDynpro explorer, this disabled the editing while permitting the user to use the Search Help.
Since the installation, the search help is no longer visible or accessible on a Read Only standard inputfield.
Do you know if there is a way to allow the search help on a read only field?
Thanks so much for your answer,
Brian Foster.

>Since the installation, the search help is no longer visible or accessible on a Read Only standard inputfield.
This was a conscious design decision on SAP's part that disabled or read-only fields should no longer fire value help. I am aware that this situation was used in the past as you describe. It is even still used in SE80 for the Web Dynpro ABAP wizards. However usability studies showed that this often confused end users and therefore it is no longer allowed. The field must be input enabled to fire the attached serach help.

How to enable/disable the input fields based on the data entered/user action in the web dynpro abap?

How to enable/disable the input fields based on the data entered in the web dynpro application abap? If the user enters data in one input field then only the next input field should be enabled else it should be in disabled state. Please guide.

Hi,
Try this code.
First create a attribute with the name readonly of type wdy_boolean and bind it read_only property of input field of which is you want to enable or disable.
Next go to Init method.
Set the readonly value as 'X'.
DATA lo_el_context TYPE REF TO if_wd_context_element.
     DATA ls_context TYPE wd_this->element_context.
     DATA lv_visible TYPE wd_this->element_context-visible.
*   get element via lead selection
     lo_el_context = wd_context->get_element( ).
*   @TODO handle not set lead selection
     IF lo_el_context IS INITIAL.
     ENDIF.
*   @TODO fill attribute
*   lv_visible = 1.
*   set single attribute
     lo_el_context->set_attribute(
       name = `READONLY`
       value = 'X').
After that Go to the Action ENTER.
First read the input field ( first input field, which is value entered field) , next give a condition
if input value is not initial then set the readonly value is ' '.
DATA lo_nd_input TYPE REF TO if_wd_context_node.
     DATA lo_el_input TYPE REF TO if_wd_context_element.
     DATA ls_input TYPE wd_this->element_input.
     DATA lv_vbeln TYPE wd_this->element_input-vbeln.

Can we do input field readonly and it will takes data only from F4

Hi experts,
I want user only fill data in inputfield by F4, not manualy , can we do somwthing for that.
Thanks & Regards
Prashant Gupta

Hi Prashanth,
   We can handle your requirement. I will give one example and it is working.
    Address - Node
     Firtst_Name-    Node attribute    and this attribute will have DDIC search help.
   Create Input field 'FIRSTNAME' for this attribute in screen with transparent container 'TC' and bind the above context to the UI element. Now this UI element is Context is 'ADDRESS.FIRSTNAME'.
Now add the below code in MODIFYVIEW hook method.The below code will add search help with read only input field but for display mode again you have to disable the search help for this field. i have not written code for that.
DATA: lo_first_name       TYPE REF TO cl_wd_input_field,
        lo_first_name_new   TYPE REF TO cl_wd_input_field,         " New input field

Input field in display mode; but F4 help has to be avail

Hi,
            i have a input field in my view and i want that one to be in display mode ( the intention is that i want to have the value to be filled from F4 help values only). I have set the read only set for the input field. I have tried all the cases of normal ddic help;OVS;Freely input help; context node info value set but no luck.
In the below forum message Re: how to provide f4 help to the read only input field i could see the input from Thomas that the Freely input help will be useful in this case;I tired this way too but no luck.
Can you please let me know do i missed any point ;your inputs are higly appreciated.
Thanks and Regards,
Satish A.

hi,Satish A.
After check your requirement, i think you can use "Freely programmed Input help".You can search them in this forum or google, i think you will get some clue.
As a reply, i summarize this topic simply. Take one example.
Scenario:
F4-help component will be used for "F4". It displays all the data in table, and you can select one record, then the F4-help will be closed and the "CARRID" will be returned to the Read-only field in your main component.
F4-help-component
(1). You should implement one WD Component which implemented the WD interface "IWD_VALUE_HelP".
(2).In this component, you can add one "Interface event", for example, named "Select". And this event has one parameter "CARRID".
(3).In the table's OnSELECT event, you can use:
method ONACTIONSELECT_ROW .
data:
    lo_Node      type ref to If_Wd_Context_Node,
    lo_Elem      type ref to If_Wd_Context_Element,
    ls_elem      type wd_this->element_table,
    lt_elem      type wd_this->elements_table.
*1. get the Solution-list context node
lo_Node = wd_context->get_child_node( Name = 'TABLE' ).
*2. set the lead selection of table
lo_node->set_lead_selection( element = NEW_LEAD_SELECTION ).
*3. get the attribute value of selected row
NEW_LEAD_SELECTION->get_Static_Attributes(
    importing
       Static_Attributes = ls_elem ).
*4. Fire interface event:
"will return the CARRID parameter
WD_COMP_CONTROLLER->Fire_select_Evt(
      CARRID = ls_elem-carrid ).
*5. close the F4 help
WD_COMP_CONTROLLER->F4_LISTENER->CLOSE_WINDOW( ).
endmethod.
In your main component:
(1). Use your F4-help component as used-component
(2). set your context attribute's input help mode as "Freely programmed". At the same time, input your component usage which is added in step 1.
(3). You should add one Event-handler for your F4-help component Interface event, for example, named "On_f4_help". you can use:
method ON_F4_HELP .
"This event handler will has one parameter named "CARRID" automatically
wd_context->set_attribute(
    EXPORTING
      name = 'IPFIELD'
      value = CARRID
endmethod.
Hope it can help you a little.
Best wishes.

HOW to include a reference currency fields in a view ?

Hello Experts,
<b>I am having Currency fields error in generic extraction</b>
I have table where I am trying to extract data to BW via generic extraction. When I tried
to extract with the TABLE its giving me an error
<b>Invalid extract structure template RPSCO of DataSource ZBW_REP3_TEST
You tried to generate an extract structure with the template structure RPSCO. This operation failed, because the template structure quantityfields or currency fields, for example, field WLP00 refer to a differenttable</b>.
Now I created a view with all the fields same as my table.
But its still giving me the same error and taking all the fields as a primary keys. I have over 12 currency fields in the table. I am confused how to fix this issue and add a currency field to my view?
hOW to include a reference currency fields in a view ?
All inputs are much appreciated.

If I add a

Do I need to tick MOD?
Please suggest.

Enable input fields in a view container

Hi,
I have inserted a view in another view's view container.
But the input fields are disabled.
can anybody tell me how to enable them?
readonly property is set to false...

Hi..
This situation may arise when the attributes (mapped to the input field in the view) are mapped to the interface controller via the component controler and the IsInputElement property of the node in the interface controller is set to True.
In this case you cannot change the cardinality of the node from the component controller also.
If this is the case, try by removing the interface controller and component controller binding.

Not able to display the values in the input fields of the view

Hi All.
I am facing an unique issue.
My custom element created in my custom node getting a null value
from a Get Vendor Details RFC written in RFC.
The values are getting populated in the custom element but not coming in the
input field of the corresponding view.
Then, I wrote this code
wdContext.nodeCustom.setLeadSelection(1);
and all the output came in the input field.
Now, after a build it is not coming in the input fields of the view.
All my custom nodes are Singleton and values are coming in the custom elements
as I can print them by wdComponentApi.getMessageManager.reportSuccess(""+customnode.getField());
All my nodes are Singleton.
Please give your valuable inputs.
Regards
Kaushik Banerjee

Hi
Check the node property
initializeLeadSelection true
if not make it true , I would suggest to make a value node of the same structure as in RFC after execuation of the RFC populate the value manually.Dont bind it directly to the UI element.

A forms developer could make those fields required with a CUSTOM.pll extension if you didn't want to use forms personalization. Both are considered customizations to standard functionality and may or may not require rework after patching or upgrades.
