WebDynpro ABAP ALV table not refreshed

Hi everyone,
I've got a master table which displays a list of items. On lead selection a query is executed and the result is displayed in a table below the first table (like a master-detail pattern).
This all works all right when the detail view is a standard webdynpro table.
However when I replace the standard table with an ALV table this is not refreshed.
I've also tried to invalidate the node in the even handler "on lead selection" and I've also coded
lo_interfacecontroller->refresh( in = lv_refresh_in ).
but to no avail.
Any ideas?

Hi,
Keep your invalidate method at the end the particular action or method.
DATA LO_ND_<Context Node> TYPE REF TO IF_WD_CONTEXT_NODE.
navigate from <CONTEXT> to <CTX_VN_ITEM_DET> via lead selection
LO_ND_<Context Node> = WD_CONTEXT->GET_CHILD_NODE( NAME = WD_THIS->WDCTX_<Context Node> ).
LO_ND_<Context Node>->INVALIDATE( ).

Webdynpro abap ALV export to excel with images problem

Hello experts,
I'm having problems with standard excel export functionality in webdynpro abap ALV.
In my table i have images taken from content server (employee photos) linked with URL to a table_cell Image, when i export the table to excel using standard function the images is showed as a broken picture with the following text:
"The linked image cannot displayed. The file may have been moved, or deleted. Verify that the link points to the correct file and location."
I'm running on sap basis 7.02 SP13 and implemented the notes 1975765 and 1985288 but not resolved this issue.
Do you have any ideas?
Thank you.

Hi Jorge,
Are you able to download the ICONs from alv table? try to use some icon source '~Icon/Add' and check out if you can download it to excel successfully.

In webdynpro for ABAP alv table issue

hello gurus,
                  i am new for webdynpro for ABAP.i strucked at one point at designing time.anybody could you suggest me on this.
thanks in advance.
let me explain my scenario first.
in my webdynpro for ABAP developement i have one alv table having ten fields.i am featching the data for eight fields from one Ztabale and updating , for rest of two fields we need to fill after displaying output using the respective F4 help. Right now these two fields are in input editable mode.now i am getting the values successfully from F4 help and at the same time it is allowing MANUAL ENTRIES also but as per my requirement it should not allow any manual entries . for this i have made these two fields are in readonly mode as like as rest of fields to avoid the MANUAL ENTRIES but at this time i didnot get any F4 helpfor those two fields.
so how can i achive my goal in this thing could any one suggest me.
my final conclusion is we need to get only F4 help values into those two fields . it should not allow any manual values at any point of time.
best regards,
babu

Webdynpro ABAP ALV tutorial - simple update or use changelog ?

I was working through the alv tutorials for webdynpro abap, and while trying to complete the
"Editing ALV in Web Dynpro for ABAP", I got to page 8 of the pdf document where it explains how to do the ONDATACHECK event handler, and it comments out the portion for updating/saving the data (as noted below), and does not explain anything further about the save.
* save data to database
{* update... => only simlate, to not change the flight data model
* content!
Now, I am new to webdynpro abap, and don't know if I am supposed to utlize the changelog for this, or if a simple update will work.
Any Ideas ?

Thank you for your answer - I am guessing from your response that a method would need to be built - similar to one which I found in the SWDP_DEMO_TUTORIALS for a webdynpro called WDT_TABLE (see below) - where a check of the table changes would need to be made before an update to the table - rather than a simple one line update statement placed at that point in the code.

Splitter Problem - ALV Grid not refreshed when selected another item

Hi Experts!!
I have a container on screen 100 which has to be split into 3 areas. Left area ->tree, Right top area -alv grid and bottom also alv grid. I created the program without splitter and it was working fine. After I added this splitter, I see that in ALV grid, the data is not being refreshed. When double clicked on an item in tree struct, ALV grid (CL_SALV_TABLE) to be shown.. Firstly it's fine but when I double click on another item, it's not refreshing the data but is showing the same previous data.
I have searched existing posts and implemented, but no luck.

How to disable Print button on WebDynpro ABAP ALV

In WebDynpro ABAP, a standard menu appears around the ALV, that has a PRINT button and an EXPORT button.
Is there anyway to disable those buttons????
Thanks
John

Hi John,
Check the interface if_salv_wd_std_functions. It contains methods which are used to hide the standard ALV toolbar buttons.

Webdynpro ABAP -- ALV Layout setting

Dear all,
In my development with ALV in Webdynpro ABAP, I want to save the ALV layout via Setting. but it seems that the layout only can be saved as user-specific, is it any possible to use it as the gobal one?
Please kindly provide me some hints. Thanks in Advance.
Best Regards,

Hi,
Yes you can make it global in administrative level.
1.In SE80 ,Double click on the name of your Web Dynpro Application .
2.Select Web Dynpro Application Menu .
3.Select Test->-> Execute in Administrative Mode from the menu.
Your application opens in administrative mode .
Go to the ALV settings make the changes and save it as some variant.
This layout will be default and global to all the users.
Regards
John Paul

Webdynpro ABAP ALV in SAP ECC6 - EHP4: To disable Column Selection

Hi All,
We are using SAP ECC6 EHP4 and for Webdynpro ABAP application, after each column a vertical white line is appearing, and I need to hide this..
SAP suggested us to disable COLUMN SELECTION I have tried the below code but still I am not able to get this done..
Can you please suggest the appropriate method to achieve the same.
Code:
* show tab COLUMN SELECTION in Settings page
CALL METHOD wd_this->alv_conf_table->if_salv_wd_std_functions~set_column_selection_allowed
EXPORTING value = ABAP_false..
here alv_conf_table refers to CL_SALV_WD_CONFIG_TABLE.
Thanks in advance.
Thanks

You have to disable the DDic binding on the column before your override text will show up:
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( ).
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` ).

ALV table not displayed in Popup

Hello Experts,
I have created a view which contains an ALV table. This view is embedded in one window.
I am opening this window on click of a button. I am reading data from one custom table and displaying it in ALV.
The problem I am facing is that ALV displays the data the very first time window is opened. After closing the window if we again open the window the ALV table is not displayed.
I have checked the code in debugging and values are coming in Node but not displayed. There is no visibility property attached to this ALV.
Every thing was working fine until patching was applied. The same code is working fine in prod but in Dev I am facing this issue.
Can any one you guys suggest me that why it is happening? Is it because of Patch upgrade and is there any sap note to resolve this.
Thanks in Advance
Amit

Hi Khandelwala,
Is the entire ALV table disappearing? as it is a popup, the view will always be destroyed when the popup window is closed. It will be again recreated once the popup window is thrown again.
However the component controller instance will not be freed and will exist.
My guess is some plugs are being fired displaying empty view.
Please let us know if it is only data that is disappearing.
Just check the stack level of ur dev and production landscapes. If Dev is on higher version, then it might be due to patch.
Thanks,
Anand

Tooltip in WebDynpro ABAP ALV

Hi,
I put a tooltip on every cell of my ALV Table.
I used this code:
DATA: lr_input_field TYPE REF TO cl_salv_wd_uie_input_field.
        CREATE OBJECT lr_input_field
          EXPORTING
            value_fieldname = lv_name_day.
        lr_input_field->set_tooltip_fieldname( lv_name_desc ).
Unfortunately my tooltip is not long enough. The shown tooltip text is only about 20 chars long.
When I try the tooltip on a "normal" InputField, the text can be longer.
Do you have any idea what to do?
Thanks a lot!
Lucie

Hi,
I just do the same things, what it is work for me. I think the problem is not about the length of tooltip, but the length of your field name ( lv_name_desc ).
Just check the length of your field name that you used as tooltip. Maybe the length of your tooltip field just around 20 characters.

Double click functionality in Webdynpro ABAP ALV

Hello!
I have web dynpro application with ALV Table.
I need to reproduce the standard R/3 functionality: after the double clicking on the table row the new window with content of that row's fields should appear in the form layout .
For example, such functionality we have in the RSDMD transaction.
So I have two questions:
1. How to catch double click in the alv table of the Web dynpro application;
2. How to represent information from the alv table row in the form layout?
Could you please help me?
Thanks,
Mariya

Hi Maria,
Say suppose I am displaying the information from SFLIGHT in an ALV format & when I click on any 1 row's CARRID I would like to fetch the corresponding BOOKING details for that particular combination of CARRID, CONNID & FLDATE then I can proceed as follows:
1) Make the CARRID cell of your ALV to appear as an LinkToAction
2) Create an event handler for the ON_CLICK event of the ALV & within this event handler fetch the information about the row's CARRID, CONNID & FLDATE. Call a popup window and display the corresponding information in this row.
Below is the code to make your CARRID field as an LinkToAction:
METHOD wddomodifyview .
wd_this->build_alv( ).
ENDMETHOD.
METHOD build_alv .

Double click in alv grid not refreshing until I click elsewhere

Hello,
I'm very new to abap and just managed to partly implement double click in an alv grid.
I also created a button that calls the exact same function as double click (selects the row and fills in the data areas on the page). When I use the button, everything works fine, but when I double click, nothing changes until I click on a tab or other form of input button on the page.
I have followed the process in debugging and can't find the fault anywhere.
My double click is implemented by:
           create object lcl_event_receiver.
           set handler lcl_event_receiver->double_click
                for search_alv_grid.
          endif.
CLASS lcl_event_handler DEFINITION.
    public section.
    methods:
    double_click         for event double_click
                         of cl_gui_alv_grid.
ENDCLASS.               "lcl_event_handler
