Modifiy column in value help

Hello Experts,
i am using value help in my web dynpro application.
key | Display Text
001 | test1
002 | test2
I can modify the key column title with method setFieldLabel:
ISimpleTypeModifiable valueType = attInfo.getModifiableSimpleType();
valueType.setFieldLabel("Test Key");
Can i also modify the display text column title?
regards

hi,
thanks for your quick answer.
If i create a new Simple Type in local dictonary can i modify the column label, but i want added the values at run-time and the dynamic add is not supported for Simple Types - or?

Variables/Input Parameters Value help not showing texts

Hello,
I have created a crystal report based on a calculation view in Crystal Reports for Enterprise 4.1 SP5, which has a input parameter on the field "Region". For the value help, I am using a custom view based on T005U in which I have made sure that RegionName field is present in the "Label Column" property of the Region field.(Required for viewing descriptions of LOVs).
In the crystal report, while previewing data in the query builder, I am able to see the value help for the input parameter in the prompt screen, which displays only the key part, but does not display the description of it. Moreover, after accepting the prompt value, the preview runs into an error(as shown below). Please note that I get the error below only when Region is a part of the output fields of the query.
Instead of input parameter, when I create a variable on the region field in the main calculation view, with the same value help view, I am able to do data preview in the query builder as also data appears in the report on running the query. But, just as in the case of input parameter value help in the prompt screen, even over here, I am only able to see the key part and not the description.
Are variables/input parameter LOV's supposed to display descriptions or just the key part? As also, any reason why I should be getting this error while using Input parameter?
Kindly let me know if I am missing something in the development of this report.
Regards,
Alston

Hi,
I hope you are taking the BEx Query as a source to the crystal report. In the BEx query check region info object should is maintained as Text and Key. If text is not maintained over there you will not be getting text in Crystal reports.

Icon in Dictionary Value Help List

Hi
I would like to add a Status-Icon like 'WEBICON_LED_RED' to the Result List of a Value Help. However, the Result List contains only of 'TextView' UI_Elements. Is there any possibility to get UI-Elements like 'Image' for displaying icons?
Thanks in advance
Daniel

Baskaran,
I think we can do with OVS, by adding new image column. correct me , if i am wrong

When I quit itunes it restarts again with the dot under the itunes logo but the iTunes window doesn't open until I click the icon on the dock. Also in the middle of the size vale in the size column the value starts with a number then a ? then a number.

Value help in ABAP Webdynpro

Hi Experts,
I have to create a value help for an icon in a table.
The full story is:
There is a table with a filed, which has the proper standard value help, which works perfectly
The problem is that this column in the table is just a "technical" field, becase it isn't displayed by the webdynpro, because in the next column an icon is displayed for the field.
Example:
FieldName = ready
Possible values: 0, 1.
The AWD display the "red Light" icon for value 0 and "Green light" icon for value 1 in the table
I'd like to display the value help for this field (it's an information for the user, what does the green/red light means)
How can I do that? Is this even possible?
Thanks
N.

Is it possible to have both thing in my field (display the icon and use the value help)
No - not really...
you can launch the value help from the link to action (in the action handler call the value help - I think I've posted on how to do this before - have a search, but if you can't find it post another question)- but it won't display that nice little dropdown icon and I'm guessing you want two types of interaction - one on click and one just to explain/choose the current value. I'd probably go with the previously mentioned solution of using a tooltip - although again you have the issue of not being able to have anything other than text in a tooltip. Alternately I'd have the custom value help launched on click of the icon and then have another button to launch any other actions
A legend somewhere in your screen might be useful - but perhaps your screen layout won't like that very much.
If you're looking for a more graphical representation of a multi state option - you might want to consider the [Threshold Slider|http://help.sap.com/saphelp_nw70ehp1/helpdata/en/dc/a65ca1b6054f06929ee40ac59f8a40/frameset.htm] rather than your own icons - but I guess it depends on your requirement.

Freely-programmed value help for a single ALV cell

Greetings everyone,
I have a freely-programmed value help that works beautifully when attached to the context element of a single field, but now I'm needing to use it in an ALV for a specific cell. Is there a way to shut off the dropdown for all of the rows (cells) in the column where I don't need it? Or, is there an appropriate workaround that can deliver the same results?
I've found several posts that address similar issues, but nothing for this exact problem.
Thanks,
Jason Block

I take it from reading your description what you want is a little more complicated than just controlling the read-only property on the input field. If I read you properly you still want to have all the cells in a column to be open for input, just on some of them you want to disable the value help. Is that correct? See these screen shots for clarification:
If you focus on the the input field in the first row, you get the value help:
http://www.flickr.com/photos/tjung/2714133068/
However if you go to the second row and focus on the same input field in this column, you don't get the value help:
http://www.flickr.com/photos/tjung/2714133094/
If this is what you want, then buckel up because this was a challenging one. The problem is that the value help specification is not done at the UI element level, but instead at the context attribute level. Therefore it can't be as simple as controlling a property on the inputField itself. What you will need to do is extend the context node that you have bound to the ALV. You need to add a second version of the attribute that is bound to your input field. In this second version you can set the value help specification to Disabled:
http://www.flickr.com/photos/tjung/2713320505
Notice from the screen shot that I also added another attirbute called CVAR (type STRING). We will need that later. It will be used to store which cell variant show be used on a particular row.
Now we must go to the place in your code where you fill the context node with data. You will need to copy the data from your primary attribute to your secondary one. In my case I was copying the values from CARRID to CARRID2. Of course for update, you would need to merge the data back together before saving it back to the database. I also set a simple odd/even pattern of controller in the cell variant. I assume you will have some actual business logic that controls this:
data odd type boolean value abap_true.
   loop at lt_f_r_sflight[] assigning <ls_f_r_sflight>.
    clear ls_c_r_sflight.
    move-corresponding <ls_f_r_sflight> to ls_c_r_sflight.
    move <ls_f_r_sflight>-carrid to ls_c_r_sflight-carrid2.
    if odd = abap_true.
      odd = abap_false.
    else.
      odd = abap_true.
      ls_c_r_sflight-cvar = 'NOVH'.
    endif.
    insert ls_c_r_sflight into table lt_c_r_sflight[].
endloop.
lo_r_sflight->bind_table( lt_c_r_sflight[] ).
Next is the logic in the initialization of the ALV. We will need to create two input fields - each bound to the different context attributes. We will make the one the primary cell editor. The other will become the cell editor of the cell variant. We then tell the column where it can get its cell variant value from:
DATA lo_cmp_usage TYPE REF TO if_wd_component_usage.
lo_cmp_usage =   wd_this->wd_cpuse_alv( ).
IF lo_cmp_usage->has_active_component( ) IS INITIAL.
    lo_cmp_usage->create_component( ).
ENDIF.
DATA l_salv_wd_table TYPE REF TO iwci_salv_wd_table.
l_salv_wd_table = wd_this->wd_cpifc_alv( ).
DATA l_table TYPE REF TO cl_salv_wd_config_table.
l_table = l_salv_wd_table->get_model( ).
l_table->if_salv_wd_table_settings~set_read_only( abap_false ).
DATA input1 TYPE REF TO cl_salv_wd_uie_input_field.
DATA l_column TYPE REF TO cl_salv_wd_column.
l_column = l_table->if_salv_wd_column_settings~get_column( 'CARRID' ).
CREATE OBJECT input1
    EXPORTING
      value_fieldname = 'CARRID'.
l_column->set_cell_editor( input1 ).
DATA input2 TYPE REF TO cl_salv_wd_uie_input_field.
CREATE OBJECT input2
    EXPORTING
      value_fieldname = 'CARRID2'.
DATA l_cv TYPE REF TO cl_salv_wd_cv_standard.
CREATE OBJECT l_cv.
l_cv->set_key( 'NOVH' ).
l_cv->set_editor( input2 ).
l_column->add_cell_variant( l_cv ).
l_column->set_sel_cell_variant_fieldname( 'CVAR' ).

How to get column default value define on table?

Hi,
I am trying to get a table column default value with no success. I am using the Oracle Data Provider for .NET 10g Release 2 (10.2.0.2)
1). OracleConnection.GetSchema( "Columns", New System.String() {"<Owner>", "<Table_Name>"} returns everything BUT default value.
2). I tried querying oracle directly (sample below) but the default value comes back blank even though the column has one defined.
Dim oracleConnection As Oracle.DataAccess.Client.OracleConnection = factory.CreateConnection
Dim oracleCommand As New Oracle.DataAccess.Client.OracleCommand( _
"SELECT data_default FROM DBA_TAB_COLUMNS WHERE OWNER = 'TEST_SCHEMA' AND UPPER( TABLE_NAME ) = 'TEST' AND UPPER(COLUMN_NAM) = 'TESTCOL'")
oracleConnection.Open()
oracleCommand.Connection = oracleConnection
Dim oracleReader As Oracle.DataAccess.Client.OracleDataReader = oracleCommand.ExecuteReader
oracleReader.GetValue(0) 'This will return blank rather than default value for the column.
oracleReader.Read()
oracleReader.Close()
oracleConnection.Close()
Any help would be appreciated.
Thanks,

Hi Rob,
I just ran up a quick test and I can't duplicate the behavior you describe.
I created a simple table as "scott":
SQL> create table def_test(c varchar2(32) default 'hello, world');
Table created.In my simple test I used the following C# code:
NOTE: There is an error in this code if using ODP.NET (see my post below for details on this)
using System;
using System.Data;
using System.Data.OracleClient;
class Program
static void Main(string[] args)
    string constr = "user id=scott;" +
                    "password=tiger;" +
                    "data source=orademo;" +
                    "pooling=false;" +
                    "enlist=false";
    OracleConnection con = new OracleConnection(constr);
    con.Open();
    OracleCommand cmd = con.CreateCommand();
    cmd.CommandText = "select   data_default " +
                      "from     all_tab_columns " +
                      "where    owner='SCOTT' " +
                      "and      table_name='DEF_TEST' " +
                      "and      column_name='C'";
    OracleDataReader dr = cmd.ExecuteReader();
    dr.Read();
    string defaultValue = (string) dr.GetValue(0);
    Console.WriteLine("Default value is: {0}", defaultValue);
    dr.Dispose();
    cmd.Dispose();
    con.Dispose();
}Since the GetValue method returns an "object" I cast the value to a string and got the correct result.
However, I don't have a 10.2 ODP.NET environment right now so I was using 11.1 for this.
In your real code I suspect that you assign "oracleReader.GetValue(0)" to something - when you say "blank" do you mean zero length or a space or something else?
Regards,
Mark

Deactivate F4-Value help in transaction PR05?

Hello,
is there any way to disable the value help for the personnel number in transaction PR05 (or at least to remove columns inside the value help)?
Thanks.

Hi,
You might have a look at its definition using transaction SE11. Click the Radio Button for SEARCH HELP and enter PREM, then click
DISPLAY. On the following screen you find the tabstrip "Included search helps" and in the list the search help PREMK for the
organizational assignment. Double-Click on PREMK to enter the search help. In the tabstrip DEFINITION you can remove
selection-method M_PREMK.

Need to change color of one column's value depending on the other column

Hi,
i have a search form which displays two column values
First column value's colour should be based on second column's value
For example, if second column has values 'Active', 'Inactive' and 'Pending'
If 'Active' , the first column value's color sholud be 'red'
If 'inacitve, another color ....
Thanks in advance,

Hi!
What we did was we added a column on the VO that returns kind of a css part (for example if a column value is 'Active' the value of this column should be "background-color:rgb(255,0,0);")
Than you use something like this on your column:
inlineStyle="#{row.StatusStyle}"where StatusStyle is the name of the column with "background-color:rgb(255,0,0);" value.
The problem here can be that the background color doesn't cover the whole column but only the text in it (so if it is null, the color is default).
If you want the whole column to be of this color you use something like this:
                                    <af:column ...>
                                      <afh:tableLayout ...>
                                        <afh:rowLayout ...>
                                          <afh:cellFormat inlineStyle="#{row.StatusStyle}" ...>
                                            <af:outputText ...>
                                            </af:outputText>
                                          </afh:cellFormat>
                                        </afh:rowLayout>
                                      </afh:tableLayout>
                                    </af:column>Basically you put another table layout inside a column instead just a outputText (or whatever control you use)
Hope this is understandable and it helps :)
It works for us.

Custom Error Message in Value Help

Hi,
In my application i have a Inputfield called "CLASS", for which i have added a value help..it has these values
B    Business
E    Economy
F    First Class
When the user enters a value(say "X") other than B, E, and F, it displays a message
<b>String "X" does not match the enumeration</b>
I want to put my own message like " Please enter a valid value" instead of the above message.
Please let me know how to do this ?
Thanks
Senthil

Senthil,
First, "looping through the list and checking the user entered value with values in the list" is possible only with non-validating actions. Using non-validating actions is a tricky task in real life.
Second, workarounds are possible, but they involves calculated attributes (like here: /people/valery.silaev/blog/2005/11/29/800format-your-way). Solving this problem generically (45 attributes is a good number to start with a generic solution) will result in solution with complexity comparable to this: https://weblogs.sdn.sap.com/pub/wlg/3309.

From two given tables, how do you fetch the values from two columns using values from one column(get values from col.A if col.A is not null and get values from col.B if col.A is null)?

From two given tables, how do you fetch the values from two columns using values from one column(get values from col.A if col.A is not null and get values from col.B if col.A is null)?

Hi,
Use NVL or COALESCE:
NVL (col_a, col_b)
Returns col_a if col_a is not NULL; otherwise, it returns col_b.
Col_a and col_b must have similar (if not identical) datatypes; for example, if col_a is a DATE, then col_b can be another DATE or it can be a TIMESTAMP, but it can't be a VARCHAR2.
For more about NVL and COALESCE, see the SQL Language manual: http://docs.oracle.com/cd/E11882_01/server.112/e26088/functions119.htm#sthref1310
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all tables involved, and also post the results you want from that data.
Explain, using specific examples, how you get those results from that data.
Always say which version of Oracle you're using (e.g., 11.2.0.2.0).
See the forum FAQ: https://forums.oracle.com/message/9362002

How do you use user defined error messages in Value Help?

Hi,
I'm currently working on a Modifiable Value Help Selector in Web Dynpro Java, and I want to use a user defined error message when I validate the values entered by a user. Currently, it's returning its default error message ("Character <string> does not match...").
Since the project requires a different error message, is there a way to override the default error message and use my defined error message instead?
Thanks!

Hi Angelo,
I am not sure why message area is showing both Custom and inbuilt messages but you can try the following:
i guess you must be using reportContextAttribute exception for showing Error messages on the input fields as well.in that case you can disable the message area so messages will appear only on the Context level ie; on input fields.
For other messages apart from validation messages you can enable the message area before reporting the exception.
make sure the boolean context variable which will be used for enabling and disabling the message area should have Readonly property set as true.
I am not sure whether this is the only solution for this but you can try and see if it works.
