Setting ALV Header text doesn't work

I'm trying to set different titles on my headers of the ALV table. To do this I do the following during the WDDOINIT of the COMPONENTCONTROLLER.
CALL METHOD WD_THIS->GO_ALV_EINSTELL->IF_SALV_WD_COLUMN_SETTINGS~GET_COLUMNS
    RECEIVING
      VALUE = lt_columns
LOOP AT lt_columns INTO ls_column.
    CASE ls_column-ID.
      WHEN 'SETTING_ID'.
        CALL METHOD LS_COLUMN-R_COLUMN->SET_FIXED_POSITION
           EXPORTING
             VALUE = CL_WD_ABSTR_TABLE_COLUMN=>E_FIXED_POSITION-LEFT
        CALL METHOD LS_COLUMN-R_COLUMN->SET_POSITION
          EXPORTING
            VALUE = '2'
        CALL METHOD LS_COLUMN-R_COLUMN->GET_HEADER
          RECEIVING
            VALUE = lo_header
        IF NOT ( lo_header IS BOUND ).
          CALL METHOD LS_COLUMN-R_COLUMN->CREATE_HEADER
            RECEIVING
              VALUE = lo_header
        ENDIF.
        CALL METHOD LO_HEADER->SET_TEXT
          EXPORTING
            VALUE = 'Einstellung'
      WHEN 'EVENT_TYPE'.
    ENDCASE.
ENDLOOP.
The debugger shows me that the different titles are updated but when it gets displayed I see the old DDIC titles. Any ideas on how to fix this?

I hope you want to change the name of ALV column in the display.
Try following code for the same:
DATA: l_ref_interfacecontroller TYPE REF TO iwci_salv_wd_table .
l_ref_interfacecontroller = wd_this->wd_cpifc_alv_table( ). " Value from the prop tab of the view
DATA: l_value TYPE REF TO cl_salv_wd_config_table.
l_value = l_ref_interfacecontroller->get_model( ).
DATA l_column TYPE REF TO cl_salv_wd_column.
DATA l_header TYPE REF TO cl_salv_wd_column_header.
l_column = l_value->if_salv_wd_column_settings~get_column( 'MATNR' ). " Name of column you want to change
l_header = l_column->get_header( ).
l_header->set_ddic_binding_field( ).
l_header->set_text( `Material Nuber` ). " Name that is to be displayed

On your iPhone you need to change your password in 2 places:
- Incoming Mail Server and
- Outgoing Mail Server
To get to the password entry for the Outgoing Mail Server you have to tap on cell smtp.live.com and again on the second view.

Since the kitkat update, my "talk to text" doesn't work on my LG G2

Since the kitkat update, my "talk to text" doesn't work on my LG G2 unless it is connected to WiFi. It says "unable to reach Google. try again later". Can somebody tell me how to fix this!? I need this feature most when I'm NOT connected to WiFi!

Hello drewzytoo, let's get to the bottom of this together! Let's first start by resetting the Voice Mate app. Go to settings, applications, keyboard settings, voice commands and clear app data. If the issue still persists, the next step is to test in safe mode: http://vz.to/1n1hKWA Keep us posted!

Rename alv header text in webdynpro abap

Hi ,
I have created two attribute PART_NUMBER and TERM_CODE in context level with type CHAR10.
AND in ALV header PART_NUMBER and TERM_CODE is displaying, which is coming from context level.
i want to rename the header of ALV to PARTNUMBER and TERMCODE.
could any one send me the sampls code or any solution?
Thanks
Rakshar

First get access to the ALV Model object for your ALV usage:
data: l_ref_cmp_usage type ref to if_wd_component_usage.
l_ref_cmp_usage =   wd_this->wd_cpuse_alv( ).
if l_ref_cmp_usage->has_active_component( ) is initial.
    l_ref_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( ).
Then access the column you want to change the header on. In addition to setting the text of the header of the column, you must also force off the data dictionary binding for the field property text.
data l_column type ref to cl_salv_wd_column.
l_column = l_table->if_salv_wd_column_settings~get_column( 'POSTING_DATE' ).
data l_header type ref to cl_salv_wd_column_header.
l_header = l_column->get_header( ).
l_header->set_prop_ddic_binding_field(
    property = if_salv_wd_c_ddic_binding=>bind_prop_text
    value = if_salv_wd_c_ddic_binding=>ddic_bind_none ).
l_header->set_text( `Posting Date` ).

don't forget to revalidate the JPanel after changing the components it holds:
    jtfColumnSize.addActionListener(new ActionListener()
      // Handle event
      public void actionPerformed(ActionEvent e)
        System.out.println(Integer.parseInt(jtfColumnSize.getText()));
        jtfUserText.setColumns(Integer.parseInt(jtfColumnSize.getText()));
        jpText.revalidate();
    });This will tell the jpText JPanel's layout manager to relayout the components that this JPanel holds. It should resize your JTextField. Note that in order to call this from within the anonymous inner ActionListener jpText will need to be declared "final". Either that or declared as a class field.

Extract PO header text in PO work flow item description

Hi,
I'm trying to display PO header text using standard PO workflow.
I managed to retrieve the PO header text information at the business object(SWO1). Now it is only displaying the last line of the PO header text. I define object &_WI_OBJECT_ID.POTEXT& in the work item text. POTEXT is of type VIRTUAL and with reference to table tline and field tdline.
How to make this field POTEXT multiline in the workflow work item?
For example PO header text contains:
Header testing1
Header testing2
Header testing3.
Currently, it is showing only Header testing 3. I'm not sure how to do coding in business objects for this case.
I am using 'READ_TEXT' function module, but how to display the text information in this field POTEXT?
Please advise. Thanks.

Hi Dev,
Thank you for your quick & prompt response.
The program that you have given is showing the text details but it is not showing complete text details, it is only showing 1st line of text. Please see screen shot for your reference, please suggest how to get complete text details.

Po header text doesn't display on po printing?

Hi experts,
We create new po doc type. Now we found when we create po and input header text manually, it can't be previewed in po form. We check some table ,it seems T166K / xT166K doesn't include this text.
May I know for new doc type, any text config need be done? Or how to setup text with doc type ?
Thanks
Alice

check in SPRO:

Change notification E_mail text doesn't work in Portal 7.0

I am changing notification E_Mail text accroding this link:
<a href="http://help.sap.com/saphelp_nw04s/helpdata/en/33/d494c86203ea40b7b44ddd471baab1/frameset.htm">http://help.sap.com/saphelp_nw04s/helpdata/en/33/d494c86203ea40b7b44ddd471baab1/frameset.htm</a>
But it doesn't work.
and I have a question ,
where should I saved the file 'com.sap.security.core.util.notification.notificationTexts_language_zh_CN.properties' in the Portal server.

Since you have not provided a more detailed desription of what is not working, and what is at error and what you assume the desired output to be for the specific user(s), I can only recommend you check the following:
1.) The email parameters are being configured per language. As such the user you are testing with needs to have the same default portal language assigned. Either by default or by personalisation.
2.) The 'com.sap.security.core.util.notification.notificationTexts_language_zh_CN.properties' file you are using may be referencing a notificationTexts_cn.properties language entry. Check the language installations are named the same and be aware this can be case sensitive.
3.) Ensure that you have the entry in the config tool in the same case.

Sales document header-- head text changes not working in VA01 if we rasie with reference to quotation

Hi,
Greetings!!
We have raised a quotation, in this quotation we have manually updated Job number (1234) and project number (9876) in header--> header text and saved the quotation.
With reference to this Quotation we raised a sales order(VA01) and here we have changed job number from 1234 to ABCD and project number from 876 to EFGHIJ and saved the sales document but system by default takes quotation job and project number only. If we go to change mode of sales document (VA02) our changes working fine.
ould you please let us know how we can overcome this issue? Or this is standard behavior or what?

Rules: header fields doesn't work

I want to use a header field List-Id: [<xyzzy.yahoogroups.com]> [without the square brackets and using the real list ID]
One of the conditions for the rule is:
List-Id: contains xyzzy.yahoogroups.com
but the rule does not move the message to the designated mailbox.
In the first box of the rule, I selected 'Edit header list' and added List-Id:
I've tried header fields before with not much luck.
It doesn't work any better if I just select Header:-(
any clues?
tnx
jt

I have the same problem in Mavericks Mail. Trying to have a rule trigger on "List-Id" contains whatever, the rule never triggers. I've verified that the field exists in the message.

Inserting of transitions & text doesn't work !!

I made my first iMovie film, reading very carefully the Help and Manual files.
Up to now two things won't work !!! Inserting transitions or text in between the fragments doesn't work. I can select the transitions and text icons but when I draw them to paste, they won't fit or drop in the space between the fragments. Also the automatic insert of transitions doesn't work. The icon which should appear between the fragments doesn't work.
Please Help !

Up to now two things won't work Inserting transitions or text in between the fragments doesn't work.
When you say "fragments" here, how long of a clip are you referring to as a fragment? Since most effects, transitions, and titles normally create an overlap of the preceding and succeeding segments, these segments or "fragments" do have a minimum length limitation for the insertion to take effect.
