Action (navigation) when click on Hyperlink field in ALV web dynpro

Hi - I had a question about Hyperlink in ALV web dynpro and it was answered in Link: [web dynpro abap ALV link to (hyperlink);
Now I need to click the Hyperlink field and navigate to another screen.
i.e. I have a Object ID (PR Number) when I click the PR number I need to open the PR Document also another case is at the item level if the PR has more than one item I'm showing the word "MULTIPLE" so if the user click on Multiple I need to show all the items (material) in another ALV table that I already create.
Thanks for your help!

Hi,
As per my understanding, there are PR number and Material and other columns in the SAME ALV table right.
There is a ONCLICK event for ALV not for the VIEWCONTAINTERELEMENT.
In the View where you have the ALV as component usage under view's properties, you have ALV usage right.
Now, under the METHODS tab of the ALV, implement an event
Onclick EventHandler ONCLICK(press F4) of that ALV.
Now the Click event is implemented for that ALV. When ever you click on any column(Hyperlink) this gets called.
Here there are parameters that you need to use it. R_PARAM has both the index and the element.
Based on the COLUMN you can call the respective event.
The index that you have clicked i shown from r_param->index and you can also know ATTRIBUTE name(column name).
If attribute eq 'PRNUMBER'
*call the Purchase requistion transaction
elseif attribute eq 'MATNR'.
*call the popup for other ALV as component usage to display item details.
endif.

Hope this is clear.

Context not updated from adobe from fields to ABAP web dynpro every time

Hi,
I work through a turtorial for interactive adobe form in web dynpro. The turtorial link is as following:
https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/media/uuid/c766e918-0b01-0010-99b1-c2b78cd059b3?prtmode=navigate
I use Active X adobe form display type and submit button. Basically, it works.
My problem is the 1st time I change the out_amount in adobe form and click 'Submit'. Everything OK. The corresponding context field in Web Dynpro is updated and showed in my own web dynpro field.
Then, I change the out_amount again in Adobe form and click 'Submit' again. The context is not updated.
The interesting thing is when I click 'Submit' the 3rd time, it works again. Same situation happens for 4 and 5 times click 'Submit' and so on.
It seems I need to click 'Submit' two times and the web dynpro context is then updated.
Is there anyone have any clue about my problem?
Thank you in advance!
Trey

Please provide the solution.......

I want to editable description field in my web dynpro application

Hi expert,
The requirement is to make the Description field editable. However, the container for the dynpro only appears to allow for a certain type of action and is essentially used to display the Line Item details, giving no option to change the Line Item Description.
so i want to editable in this description field in my web dynpro application /SAPSRM/WDC_DOTC_PC_I_BD .
Kindly give me soulation ASAP.
Thanks and Regard's.
Vikash

Thanks for the reply.
The name of the view is V_PC_DOTC_ITM on which we have the records. On each line item there is a description field which is of type (LinkToAction). I want to enable user so that it can change the Description text (I will handle the action). Also, if you have any idea about updating the database table from here as it needs to be updated in BBP_PCPOS table.

Search help that populates two fields on a WEB dynpro page

Hi there,
I have created a search help based on a single table ( QPCD ) with two exporting parameters CODEGRUPPE and CODE. When the user selects a their desired entry i would like it to poulate the relevant two fields on the web dynpro screen. I know in a normal dialog screen you could get this to happen automatically, but when implementing it into a web dynpro from abap screen it only returns the first value into the field that the search help was called from. Anyone know how i could get both fields populated?
Thanks in advance
Regards
Mart

check http://help.sap.com/saphelp_nw04s/helpdata/en/5d/395e4254139041e10000000a1550b0/frameset.htm
It is not that hard.
Create a new webdynpro component and implement IWD_VALUE_HELP in this component.
go to the component controller of you new component and add a new attribute:
listener type ref to IF_WD_VALUE_HELP_LISTENER.
in the method set_value_help_listener add the line:
wd_this->listener = listener.
then you can create as much views and things you need for your search help.
To set a selected value just add a method to your component controller which takes the values as import parameters. if you only want to set the value for the attribute it was requested for:
wd_this->listener->F4_CONTEXT_ELEMENT->set_attribute(
    name = wd_this->listener->F4_ATTRIBUTE_INFO-name
    value = <value>
This is the save way
But you can also call
wd_this->listener->F4_CONTEXT_ELEMENT->set_attribute(
    name = 'CODEGRUPPE'
    value = <value_codegruppe>
wd_this->listener->F4_CONTEXT_ELEMENT->set_attribute(
    name = 'CODE'
    value = <value_code>
But keep in mind that if the structure of the element changes, this could lead to short dump if the name of the attribute changes or the attribute was deleted.
if you want to close the search help window call wd_this->listener->close( ).
Hope this helps.
Cheers,
Sascha

Adobe Presenter 9 navigation to webpage was canceled when click email hyperlink

Windows 7, IE 10, Adobe Presenter 9
I have an email hyperlink created in PPT/Presenter that works fine within PPT. However, when I publish the course to My Documents and view the presentation, once I click the email hyperlink, it opens an email but opens an additional window..."Navigation to webpage canceled". It reacts this same way when published to our LMS. The user will need to close the extra window, which may cause confusion. Our IT department has looked at my IE security settings and I have set my flash security settings to "allow" for My Documents folder. I went back to a similar course I created a couple of years ago, but I do not receive this message when I click the hyperlink. I was using an older version of Presenter at that time.
Has anyone experienced this same issue and had a resolution?
Madonna

Hi,
Could you perform the followings:
Make sure there're no duplicate records in the DNS Servers
Flush your DNS Cache at the Server & Client
Refresh any DNS Cache at the HLB (if any)
When the error appears, right click on the console and provide a screenshot on this
If you suspect that FE1 is the culprit, had you tried turning it off and monitor the situation?
Thanks!

How to populate the relavent fields when clicked on a field

I am trying to populate the relevant fields of screen(MODULE POOL PROGRAM) when i am
clicking on a field. Search help/ value request is provided to that field.
so Can any one help me with this scenario. IF POSSIBLE PLEASE SEND THE SOLUTION
WITH THE CODES.
POINTS WILL BE REWARDED.

Hi
use this for F4 help on field
For F4 Values on Screen:
PROCESS ON VALUE_REQUEST
using module call starting with FIELD i.e FIELD field MODULE module
There are number of function modules that can be used for the purpose, but these
can fullfill the task easily or combination of them.
DYNP_VALUE_READ
F4IF_FIELD_VALUE_REQUEST
F4IF_INT_TABLE_VALUE_REQUEST
POPUP_WITH_TABLE_DISPLAY
DYNP_VALUE_READ
This function module is used to read values in the screen fields. Use of this
FM causes forced transfer of data from screen fields to ABAP fields.
There are 3 exporting parameters
DYNAME = program name = SY-CPROG
DYNUMB = Screen number = SY-DYNNR
TRANSLATE_TO_UPPER = 'X'
and one importing TABLE parameter
DYNPFIELDS = Table of TYPE DYNPREAD
The DYNPFIELDS parameter is used to pass internal table of type DYNPREAD
to this FM and the values read from the screen will be stored in this table.This
table consists of two fields:
FIELDNAME : Used to pass the name of screen field for which the value is to
be read.
FIELDVALUE : Used to read the value of the field in the screen.
e.g.
DATA: SCREEN_VALUES TYPE TABLE OF DYNPREAD ,
SCREEN_VALUE LIKE LINE OF SCREEN_VALUES.
SCREEN_VALUE-FIELDNAME = 'KUNNR' . * Field to be read
APPEND SCREEN_VALUE TO SCREEN_VALUES. * Fill the table
CALL FUNCTION 'DYNP_VALUES_READ'
EXPORTING
DYNAME = SY-CPROG
DYNUMB = SY-DYNNR
TRANSLATE_TO_UPPER = 'X'
TABLES
DYNPFIELDS = SCREEN_VALUES.
READ TABLE SCREEN_VALUES INDEX 1 INTO SCREEN_VALUE.Now the screen value for field KUNNR is in the SCREEN_VALUE-FIELDVALUE and can be used for further processing like using it to fill the internal table to be used as parameter in F4IF_INT_TABLE_VALUE_REQUEST ETC.
F4IF_FIELD_VALUE_REQUEST
This FM is used to display value help or input from ABAP dictionary.We have to pass the name of the structure or table(TABNAME) along with the field name(FIELDNAME) . The selection can be returned to the specified screen field if three
parameters DYNPNR,DYNPPROG,DYNPROFIELD are also specified or to a table if RETRN_TAB is specified.
CALL FUNCTION 'F4IF_FIELD_VALUE_REQUEST'
EXPORTING
TABNAME = table/structure
FIELDNAME = 'field name'
DYNPPROG = SY-CPROG
DYNPNR = SY-DYNR
DYNPROFIELD = 'screen field'
IMPORTING
RETURN_TAB = table of type DYNPREAD
F4IF_INT_TABLE_VALUE_REQUEST
This FM is used to dsiplay values stored in an internal table as input
help.This FM is used to program our own custom help if no such input help
exists in ABAP dictionary for a particular field. The parameter VALUE_TAB is used to pass the internal table containing input values.The parameter RETFIELD
is used to specify the internal table field whose value will be returned to the screen field or RETURN_TAB.
If DYNPNR,DYNPPROG and DYNPROFIELD are specified than the user selection is passed to the screen field specified in the DYNPROFIELD. If RETURN_TAB is specified the selectionis returned in a table.
CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'
EXPORTING
RETFIELD = field from int table whose value will be returned
DYNPPROG = SY-CPROG
DYNPNR = SY-DYNNR
DYNPROFIELD = 'screen field'
VALUE_ORG = 'S'
TABLES
VALUE_TAB = internal table whose values will be shown.
RETURN_TAB = internal table of type DDSHRETVAL
EXCEPTIONS
parameter_error = 1
no_values_found = 2
others = 3.
POPUP_WITH_TABLE_DISPLAY
This FM is used to display the contents of an internal table in a popup window.The user can select a row and the index of that is returned in the CHOISE
parameter.The VALUETAB is used to pass the internal table.
A suitable title can be set using TITLETEXT parameter. The starting and end position of the popup can be specified by the parameters STARTPOS_COL / ROW and ENDPOS_ROW / COL .
CALL FUNCTION 'POPUP_WITH_TABLE_DISPLAY'
EXPORTING
ENDPOS_COL =
ENDPOS_ROW =
STARTPOS_COL =
STARTPOS_ROW =
TITLETEXT = 'title text'
IMPORTING
CHOISE =
TABLES
VALUETAB =
EXCEPTIONS
BREAK_OFF = 1
OTHERS = 2.
e.g.
DATA: w_choice TYPE SY-TABIX.
DATA: BEGIN OF i_values OCCURS 0 WITH HEADER LINE,
values TYPE I,
END OF i_values.
PARAMETRS : id TYPE I.
AT SELECTION-SCREEN ON VALUE-REQUEST FOR id
i_values-values = '0001'.
APPEND i_values.
i_values-values = '0002'.
APPEND i_values.
i_values-values = '0003'.
APPEND i_values.
i_values-values = '0004'.
APPEND i_values.
CALL FUNCTION 'POPUP_WITH_TABLE_DISPLAY'
EXPORTING
ENDPOS_COL = 40
ENDPOS_ROW = 12
STARTPOS_COL = 20
STARTPOS_ROW = 5
TITLETEXT = 'Select an ID'
IMPORTING
CHOISE = w_choice
TABLES
VALUETAB = i_values
EXCEPTIONS
BREAK_OFF = 1
OTHERS = 2.
CHECK w_choice > 0.
READ TABLE i_values INDEX w_choice....now we can process the selection as it is contained
...in the structure i_values.
Other FM that may be used to provide input help is HELP_START .

Firefox does not load the website when clicking a hyperlink in another program

I am using Firefox 5.0.1 in Snow Leopard 10.6.8. When I click on a hyperlink in another program, Firefox launch but show me a blank page, instead of the web page of that hyperlink. This only happen if Firefox is not launched prior to clicking the hyperlink. This mean, if I am already using Firefox (Firefox is opened) and I click on the hyperlink in other program's document, Firefox will launch that web page. Is there any setting that I need to do?

I read those before .. but my problem is not any one of them !
when i set proxy on firefox it does not work !
when i set proxy on IE then setting firefox to system proxy it work !!

Double click on list field in ALV grid control

Hello all,
I developed a report with a ALV grid control. I would like to move some functionality from marking a line and pressing a button in the status line to double clicking a specific field in the output list and execute a command there (i.e. double click on PO number and go to PO display TAC then). Can anybody provide some example coding for that?

Problem when user change between fields in ALV

Hi guys.
The problem is: In ALV reports, EDIT mode, when I change between fields, the new field gets selected (the data get selected in blue or gry color), so I can write over new values. The problem is that some users when try to change to another field, the new field doesnt get selected, so he needs to select all the value and then write the new values. Is it clear?
I checked with the user in another PC using his user in SAP and when she changes to another field, the new field gets selected. Then I checked in her PC doing the same, and when I moved to another field, the new field doesnt get selected, so i need to select myself and then write.
In my PC I can change fields, tabbing, and the new fields get select, but in her PC i can't do that.
Is it a problem of windows? or SAP logon?
Does anybody know about this issue?
Regards
Miguel

I would have checked her GUI version. Maybe she has another version than you !!

How can I open a popup after clicking in a table cell using Web Dynpro?

Hello,
I am using Web Dynpro to create an application and I would like to click in a table cell and then a popup with confirmation appears.
I already have a table with the information that is displayed in the browser. In fact, I just added a column with images that are print icons.
My problem is that I don't know how to implement the method to set the action: when clicking on the print icon, a popup appears.
Thank you very much in advance.

HI Rafael,
Please check the below sample code
To quickly create dialog boxes of a standardized layout (for example, for the confirmation of changes to current data) you can call the CREATE_POPUP_TO_CONFIRM method of the IF_WD_WINDOW_MANAGER. You do not need to create a separate window for this. The dialog box is created automatically by the runtime.
●      The CREATE_POPUP_TO_CONFIRM method creates an object of the type IF_WD_WINDOW; the dialog box can be created using its parameters.

hi ,
pls use the ZCi layout for the adobe interactive form .
Need to Insert the web dynpro script to the form.
Note: Make sure to upgrade the Adobe Interactive for ZCI type using SFP_ZCI_UPDATE transaction
Subsequently, check whether the update of the ZCI was successfully completed. To do this, open your form in the Adobe LiveCycleDesigner and check the version information of the ZCI script. The ZCI script is available on the "Hierarchy" tab page under the "ContainerFoundation_JS" name. The version must be800.20080513120641.469612.469346.

No editable form fields in ABAP Web Dynpro

Hi,
I created a form with layout type ZCI. The interface type is "ABAP Dictionary-Based Interface".
This form I embedded in a abap web dynpro component.
In the ABAP WD interactive form element I marked the enabled property.
Unfortunately the displayed form fields are not editable.
When I use a interface of type "XML-Schema-Based Interface" the fields are editable.
Is this a bug or is something missing?
I am using Live Cycle Designer 8.1 and SAP_BASIS 7.0, EHP 2, SP07
Thank you and best regards,
Eddy

Hi Eddy,
In your Interface, you probably have to pass the "Fillable" flag in your importing /1BCDWB/DOCPARAMS structure.
I've developed many forms over the past few years and have learned that when using web dynpro, it's almsot exclusiely easier to use the XML-based schema than DDIC.
The only time I'm using DDIC instead of XML when in WDA, is because I'm having to pass in rich text formatted objects through a Text Node.

Hi
I created the "read" and "update" methods in my application service. How can I call them? I created and implemented the methods just like here: https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/340fc0ea-0c01-0010-74bf-965b11031e77
Operations:
- readMyEntityService:
- updateMyEntityService
Implementation:
retValue = getMyEntityService().read(key);
getMyEntityService().update(dS0);
In Web Dynpro there is this update method with the code above (in my original post).
How can I call the update-method????????
Kind regards
Bettina
