How to make Popup LOV Not Editable?

Hello,
I started using a Select List (named LOV) as an element in a report. However, I go the error:
ORA-20001: Error fetching column value: ORA-06502: PL/SQL: numeric or value error: character string buffer too small
So I switched to a Popup LOV (named LOV) which is working. However the Popup LOV is a list of part numbers that I donot want the user to change. I want him to select from the list I give him and only this list. After the Popup LOV closes the user can modify the text box that the part number the user selected from the Popup LOV appears in. So how do I make the text box next to the Popup LOV icon not editable??
Thanks for the help...

Hello, not sure if you are using "Popup LOV(fetches first rowset)" or not, but switching to "Popup Key LOV(Displays description, returns key value)" might
work for you.

Geoff

How to make a JTextComponent not editable, not focusable but Highlightable?

Hi,
When i set a JTextField not focusable, it wont allow me to do the highlight and do the copy and paste thing.
can some one give me an example of how to add a highlighter in a JTextCompnent when it's not focusable.
thanks in advanced.

I'm having the same issue. Can you make it focusable, but not traversable so it doesn't get picked up when tabbing?

Cbih82 "Accident details" - How to make older entries not editable

Hello Experts,
Is there a way in CBIH82 to set the "Accident details" long text field (under involved tab) in order that older entries cannot be modified?
What I'd like would be like in maintenance notifications. No Changes to Existing Long Text.
When someone add characters to the long text field, system automatically add a log line (a timestamp containing user + date + hour) before text and make the text unchangeable by anyone after saving. However, the long text can be supplemented, the older entries would be greyed out.
Is there a key in IMG or any other way to make the system behave that way? I want to prevent people erasing previous text enterred in that field.
Thanks,
Francois

Hi Francois,
This seems to be a genuine requirement, and even more when it can be seen available in the case of maintainance notifications. But, unfortunately this functionality is not available for "Accident details" long text.
The most you may do as an alternative is to utilize "Documents" functionality. The documents uploaded in this tab has inherent SAP DMS benefits, whereby you can track changes made to a particular DIR (administrative details). You may also make the documents password-protected for unintended access, However, you can not make older entries grayed out obviously.

How do I change the Not Editable flag of a variable?

How do I change the Not Editable flag of a variable? I need to edit the variable but right now the Not Editable box is checked.

You can't do it unfortunately. That's why it pops up a warning when you check it in the first place.
Ok seriously though there is a workaround for this. It's a total hack but may get you back to where you need to be without having to copy everything to a new sequence file.
WARNING: Not sure what versions of TS this will work with.
With the offending sequence file open go to Edit>>Sequence File Properties.
On the General tab change the File Format to XML.
Click OK.
Save the sequence file.
Now browse to where you saved the sequence file and open it with Notepad.
Search for FileGlobal and look for the offending variable. <MyGlobal classname='Num' valueflags='1'>
It should have a property called valueflags. It will be valueflags='1'.
Remove that property altogether. So it should be something like this: <MyGlobal classname='Num'>
Save it and reopen it in TestStand.
You may need to change it back to binary format from within TestStand.
If deleting it gives you problems then just change the valueflags to 0.
Hopefully this helps.

How to make dyn/admin not to prompt for username and password?

Hello all
How to make dyn/admin not to prompt for username and password? I am writing a selenium job to automate cache invalidation to load test a production issue we are facing. Selenium is opening a fresh firefox session and prompting for username and password every time. I am also trying to modify my script such that it will use the same session again and not prompt for username and password. But I thought of asking this question in the group.
Your inputs will help a lot.
Thanks,
Sundar

Hi,
You can set enabled property of /atg/dynamo/servlet/adminpipeline/AuthenticationServlet/ to false. It will not prompt for authentication.

Dear Michael, good day!
1. As per your instruction, I turned off iTM.
Small discrepancy – where are two screens with iTM switch:
-Settings > iTunes & App Store.
-Settings > Music
I switched OFF in both.
NB: I turned device to English for convenience.
2. My next step was Setting > General > Usage – tapped {Music};
{All music} screen appeared; I swiped it and taped Delete.
3. I performed “hard reset” …………………………………..
4. Switched back On iTM
5. Taped Music app on Home screen
iTM has started – (it took 18 minutes to completed, 60 mbps Wi-Fi speed )
Regret to inform… All the same:
Erase and reset to factory default? Or I did smf wrong?

How to make a JScrollPane not getting Focus?

When i tab out from a textfield inside a scroll pane focus is going to ScrollPane .And if i press tab once more then only focus is going to other textField which is outside the scrollpane.

How to make the text_field to editable in the adobe document?

Hi, expert,
I meet a problem when I develop a WDA. I hope to get your help. Thanks a lot. The following is my action:
Action:
1. I am using "Text Field" control rather "Text" Control in the pfd form by transfer code "sfp". I make sure in Object Palette under value tab type is : user entered - optional in the layout tab in the pfd form. The textfield is editable in the PDF preview.
2. Add the pdf forms to webdynpro application and set "sss" to the inputfield("Text Field") through context in the WDA.
3. Run the WDA. In the IE, I found the textfield in the PDF is not editable. How can I make the textfield to editable?
Whether I need change the code or others to make text_field to editable?
Do you give me some hints? Thank you very much.

Hi Volker,

When I compile the WDA, the WDA don't occur any error. The WDA occurs error when I run the WDA.
1. In the st22 transcation code, I found the following code:

How to make the text_field to editable in a adobe document in the WDA?

Hi, expert,
I meet a problem when I develop a WDA. I hope to get your help. Thanks a lot. The following is my action:
Action:
1. Make a pdf forms (interactive form) with textfield named A_textfield in the webdynpro application. The textfield is editable in the PDF preview when I creat the pdf form using transfer code 'sfp'.
2. Add the pdf forms to webdynpro application and set "sss" to the inputfield through context in the WDA.
3. Run the WDA. In the IE, I found the PDF document with the text_field, but the textfield in the PDF is not editable.
How can I change the code or others to make text_field to editable?
Do you give me some hints? Thank you very much.
The following is my code in the WDA:
method WDDOMODIFYVIEW .
********Make INTERACTIVE_FORM to editable。******
data:
    lr_interactive_form type ref to cl_wd_interactive_form,
    lr_method_handler   type ref to if_wd_iactive_form_method_hndl.
lr_interactive_form ?= view->get_element( 'INTERACTIVE_FORM' ).
lr_method_handler ?= lr_interactive_form->_method_handler.
lr_method_handler->set_legacy_editing_enabled( abap_true ).
data:
    Node_Zz_00_Test_Form_000            type ref to If_Wd_Context_Node,
    Elem_Zz_00_Test_Form_000            type ref to If_Wd_Context_Element,
    Stru_Zz_00_Test_Form_000            type Wd_This->Element_Zz_00_Test_Form_000 ,
    Item_TEST1                          like Stru_Zz_00_Test_Form_000-TEST1.
navigate from <CONTEXT> to <ZZ_00_TEST_FORM_000> via lead selection
Node_Zz_00_Test_Form_000 = wd_Context->get_Child_Node( Name = wd_This->wdctx_Zz_00_Test_Form_000 ).
get element via lead selection
Elem_Zz_00_Test_Form_000 = Node_Zz_00_Test_Form_000->get_Element( ).
get single attribute
Elem_Zz_00_Test_Form_000->set_Attribute(
    exporting
      Name = `TEST1`
      Value = 'sss' ).
endmethod.

Hello Wang,
Just for confirmation: The interactiveform ui element is enabled, right? By default, it's disabled.
Best regards,
Thomas
