ABAP WebDynpro Customised Screens

Hello,
We are currently trying to build some new ERP transaction screens using ABAP WebDynpro having the same layout as the ESS/MSS business packages which are of course built using Java WebDynpro. So basically looking at building screens which have the guided procedures format (some sort of a wizard which guides you through a few steps to complete the transaction).
Was wondering if we can have a similar interface built using ABAP WebDynpro as is avaialble in JAVA WebDynpro for completely new transactions (we are not tring to modify the ESS/MSS existing business package iViews).
Thanks in advance.

Hi John,
WDA and WDJ have the same roots and hence share the same programming model. This includes the ui element model as well. There are very few exceptions where some platform specific adoptions had to be made (such as for the FileUpload) or where a slightly different focus had one platform implement a certain feature or ui element earlier than the other one.
Regarding extensibility, WDA offers features like the enhancement framework. As far as I am aware, ESS/MSS has its own extensibility support allowing you to generate new forms and processes. Since I am not an expert on this matter, I might be mistaken as well. So my suggestion would be to check the ESS/MSS documentation regarding any built-in extensibility.
Best regards,
Thomas

Is it possible to launch a Screen Personas screen from an ABAP WebDynpro application?

I am running SAP EHSM Incident Management within SAP Portal. EHSM has an ABAP WebDynpro frontend based on BOPF/FPM
In the same portal session for a single user, we want to be able be in an
active record in EHSM and then launch a screen personas screen based on a
SAPGUI transaction from either a button click or portal tab click. As part of
the launch, we want to pass an HR PERNR ID to the Screen Personas/SAPGUI
transaction from the active record in EHSM and run a search. Is it possible to
do this? Project team is saying this is a technical limitation.
I know that Screen Personas cannot be used for a WebDynpro screen, but we just want to launch a screen and pass a parameter. We assumed during blueprint this would be possible.
Thanks

This is definitely possible.
Here is a link containing an example of building the URL to start a transaction via Personas and pass a variable plus a command in the URL. This could be enhanced with specifying the flavor as well.

How to launch an ITS screen from an ABAP WebDynpro Button Action

Hello All,
I have a requirement to launch an ITS Screen from ABAP WebDynpro. There will be abutton on the WebDynpro screen and when the user will click on that button, the ITS Screen will be launched.
Can anyone please provide us some sample applications or sample code to achieve the above functionality.
Points will be rewarded.
Thanks
Shyam

Hi Shyam,
You can achieve by using Launchpad Customizing and the Launchpad Navigation API's. Just make and entry on transaction LPD_CUST, create a launchpad role, add you target application there.
At run time under the UI button you can call the API provided by CL_APB_LAUNCHPAD_API -->LAUNCH_APPLICATION to open the application. You can find many material on Internet for the same, with examples, even try some where-use in your system.
I found one more helpful link.

Adding an ABAP Webdynpro app to the ESS overview screen

I am trying to add an ABAP webdynpro page to the ESS overview screen, I have managed to add URLs without a problem and have found a tutorial to add Java Webdynpro pages however this does seem to apply to ABAP webdynpro.
Thanks
J

Julian,
what problem are you facing in adding.
you can create an iview for the WDA application and in the HomePage Framework you can create resources and services which will point to that iview and add that service to the ESS Overview.
Thanks

ABAP Webdynpro: Creating a table on webdynpro screen to enter new data.

Hello Experts,
Does anyone know, how to create a table on webdynpro screen that can be used to enter new data in database?
I have tried to create a Table UI element (with Standard Cell Editor as Input Field) but it is "Display only" if there is no data in the table. This means, while you can use it to modify the data if some data already exist, but you cannot use it to enter new data if no data already exist. What I am looking for is something similar to a Table Control (or Step-Loop) functionalty of a traditional (non webdynpro) SAP screen. How to achieve this in Webdynpro for ABAP?
Thanks in advance.
ABAPer

Even if no data is not there, you can pass blank work areas to table, so now table will blank rows where you can enter the data even if previous data is not there.
below is the sample code to get blank rows in table in order to enter data.
DATA LO_ND_N_EDUCATION1 TYPE REF TO IF_WD_CONTEXT_NODE.
DATA LO_EL_N_EDUCATION1 TYPE REF TO IF_WD_CONTEXT_ELEMENT.
DATA LS_N_EDUCATION1 TYPE WD_THIS->ELEMENT_N_EDUCATION1.
navigate from <CONTEXT> to <N_EDUCATION1> via lead selection
LO_ND_N_EDUCATION1 = WD_CONTEXT->GET_CHILD_NODE( NAME = WD_THIS->WDCTX_N_EDUCATION1 ).
DATA: ET_DATA TYPE WD_THIS->ELEMENTS_N_EDUCATION1,
EW_DATA TYPE WD_THIS->ELEMENT_N_EDUCATION1.
DO 10 TIMES.
APPEND EW_DATA TO ET_DATA.
ENDDO.
get element via lead selection
LO_EL_N_EDUCATION1 = LO_ND_N_EDUCATION1->GET_ELEMENT( ).
LO_ND_N_EDUCATION1->BIND_TABLE( NEW_ITEMS = ET_DATA SET_INITIAL_ELEMENTS = ABAP_FALSE ).
now table will have 10 rows, here node name is N_education1.
Thanks and REgards

Dynamic screen field layout - ABAP webdynpro

Hi,
I am rather quite new to ABAP webdynpro - one of my requirements is that based on a Custom table (so to say a custom built customizing table) I need to display fields - the Customizing table could say that for region America - we need the following fields to be supressed, the same set of fields for Japan could be Mandatory, and for Latin America could just be display only.
Is there anyway this could be acheived in Webdynpro (ABAP) - I presume that the supressed fields for America region will not be displayed but instead the common fields for America and Japan would be out of sync as far as screen layout is concerned. An ideas or guidance on how to accomplish this would be greatly appreciated.
Regards....

Hi,
you can loop on your table which gathers all the fields in it, add an attribute to your
table stating the required or not parameter and adding it to the 'state' parameter in
the new_inputfield method.
In the Wiki I added a page for dynamic UIelement creation based on DDIC properties
(wiki is down, so i don't have a link to it)

How to open a brfplus Catalog from abap webdynpro screen.

How to open a catalog from abap web dynpro application. and also what roles are to be provided to a user for restricting access only to the objects in the given catalog.

Hi Pratik,
do you use NetWeaver 7.0, Enhancement Pack 2 (or higher)?
Then you can then define an own UI mode class and set it via SET_UI_MODE( ) in IF_FDT_WD_UI_EXECUTION before you call EXECUTE_CATALOG_BROWSER().
An explanation how to define a UI mode class is available in the chapter "Configuration through a UI mode class (7.0/7.1 EHP2)" of the document [Embedding a BRFplus Object in an ABAP WebDynpro Application|http://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/50e44bf9-9135-2d10-2ea2-b13e5be8661d]
Hint: With help of the interface IF_FDT_WD_USER_CONFIGURATION you have the possibility to hide views in the navigation view by using the respective, listed parameters (e.g.. GC_PARAMETER_FAVORITES_VIEW). Please be aware of that the configuration is just available to adapt the UI, it does not fulfill the requirements to act as an authority concept. If you do not set the parameter GC_PARAMETER_HIDE_SETTING_DLG of the interface IF_FDT_WD_CONFIGURATION to false, the user is also able to change it via the configuration dialog in the BRF+ workbench.
With the current available BRF plus standard authority concept you can prevent that the user can see the content of objects like applications but you have no influence to prevent the user from seeing UI artifacts like the repository tree. Please consult the documentation to learn more about its capabilities.
Kind Regards,
Marco

Doubts in ABAP WebDynpro

Hi Experts,
I am new to ABAP WebDynpro and self-learning going through SDN stuff and other online-help. Please provide me
your kind explanation on below doubts.
1. When do we use GET_ATTRIBUTE and GET_STATIC_ATTRIBUTE
2. How to read the index of a particular selected row in table?
3. How do you change position of a particulr node dynamically?
4. Is it possible to execute a component without a window?
5. Is it possible to run a VIEW without embeding into a window in Webdynpro application?
6. How to read the content entered in PARAMTER and SELECT-OPTION elements in ABAP Webdynpro? Can anybody pass code how to read entries?
I mean GET_ATTRIBUTE or GET_STATIC_ATTRIBUTES is used for reading attribute value.
7. Is it possible to fix the Message window position? Show at the bottom of a screen? Please provide some code for this.
8. Is it possible to change the color of a laber attached to a attribute dynamically? For example somefield is mandatory but you forgot to enter and press on u2018Continueu2019 then program should show that elementu2019s lable with redcolor text. Please provide me example code.
Thanks in advance for the support and useful explanation!
Regards,
Meera.

Hi
Refer the answers inline
1) When do we use GET_ATTRIBUTE and GET_STATIC_ATTRIBUTE
GET_ATTRIBUTE
Method to get the values of a context attribute.
The prerequisite for this method is that the application knows the data type of the attribute.
The value of the given attribute is copied to the export parameter. To do this the export parameter must have a data type to which a value can be written.
GET_STATIC_ATTRIBUTES
This method copies the static attributes to the transferred variable. If the structure is not identical, a move-correspondingis performed, which is not as efficient as a direct move, but is still useful in many cases.
Static attributes are those that either have been declared or that belong to the structure with which the node was declared.
2) How to read the index of a particular selected row in table?
data: lr_element type ref to if_wd_context_element,
          lv_index type i.
lr_element = wdevent->get_context_element( name = 'CONTEXT_ELEMENT' ).
lv_index = lr_element->get_index( ).
3) How do you change position of a particulr node dynamically?
    Explain Bit deeply
4) Is it possible to execute a component without a window?
    No it is not possible, actually the component view can be viewed by embedding it to the window
5) Is it possible to run a VIEW without embeding into a window in Webdynpro application?
    No it is not possible, without window you cant run the view
6) Is it possible to run a VIEW without embeding into a window in Webdynpro application?
DATA LO_ND_MAIN_NODE TYPE REF TO IF_WD_CONTEXT_NODE.
DATA LO_EL_MAIN_NODE TYPE REF TO IF_WD_CONTEXT_ELEMENT.
DATA LS_MAIN_NODE TYPE WD_THIS->ELEMENT_MAIN_NODE.
DATA LV_INP_VALUE LIKE LS_MAIN_NODE-INP_VALUE.
navigate from <CONTEXT> to <MAIN_NODE> via lead selection
LO_ND_MAIN_NODE = WD_CONTEXT->GET_CHILD_NODE( NAME = 'MAIN_NODE' ).
get element via lead selection
LO_EL_MAIN_NODE = LO_ND_MAIN_NODE->GET_ELEMENT( ).
get single attribute
LO_EL_MAIN_NODE->GET_ATTRIBUTE(
    EXPORTING
      NAME = `INPUT_VALUE`
    IMPORTING
      VALUE = LV_INP_VALUE ).
7) Is it possible to fix the Message window position? Show at the bottom of a screen?
    Yes it is possible to show the messages by using the message area UI element in the needed position
8. Is it possible to change the color of a laber attached to a attribute dynamically? For example somefield is mandatory but you      forgot to enter and press on u2018Continueu2019 then program should show that elementu2019s lable with redcolor text.
    Im working onit and let you know after i complete.

ABAP Webdynpro Development - Script Error when Accessing Visual Elements

I am encountering a strange error at my client . I can't use the Abap Webdynpro visual elements to build views .
To reproduce the error :
- T-code SE80
- Open up any ABAP webdynpro component .
- Open up one of the view and go on Tab Layout .
Normal Screen : You would see many WYSIWYG items ( buttons, radiobutton , text elements etcu2026. ) at the left side u2026 these elements are used to build the view .
Here : No elements displayed and when we click on that area we get an error .
Instead of the elements to get displayed .. lines are displayed and when you try to open up ( click ) the lines , an internet explorer script error stating the following occurs ( although the abap wendynpro is edited in SAP Gui ) :
An Error has occured in the script on this page .

Recently, we have upgraded our ERP system (SAP ECC 6.0 SPS17) with EHP4 SPS8. SAP_BASIS and SAP_ABA patch level same on 701_0008.
FQDN is mantianed at icm/host_name_full parameter in system as well as in /etc/hosts file with associated system IP address.
As suggested by Ted Dinh, we do not find any duplicate MIME files in our MIME Repository (SE80) and we cleared/invalidated ICM cache many times in problem analysis.
As suggested by Thierno Diarra , in our affected system domain WDY_MD_UI_ELEMENT_CATEGORY is well maintained in value ranges.
We have raised SAP OSS Message for the same, they told us to check dns server connectivity/settings with the affected system. we did the suggested DNS settings in affected system. But still the same error message is occuring. They have suggested same sap notes like #979039 and #1009930 & #1483210 , but all the corrections/suggections/SICF service status as mentioned, are found OK in our system.

PR05 Transaction Iview from Abap Webdynpro

Hi,
From abap webdynpro, on action of one button, i'm calling PR05(Travel Expense Manager) screen by passing the parameters as follows and calling NAVIGATION_ABSOLUTE method:
BUS_PARAMETER-KEY = 'PTP00-PERNR'.
BUS_PARAMETER-VALUE = LS_EMPLOYEE_NODE-PERNR.
Insert BUS_PARAMETER into table BUS_PARAMETER_LIST.
CLEAR BUS_PARAMETER.
BUS_PARAMETER-KEY = 'PTP1000-REINR'.
BUS_PARAMETER-VALUE = LS_HEADER_NODE-REINR.
Insert BUS_PARAMETER into table BUS_PARAMETER_LIST.
It opens PR05 screen, with the correct employee list, but it does not populate the tripnumber and also it should skip the first screen.
In the IView, i have already given OKCODE='MOD' for change of the trip and also PROCESS_FIRST_SCREEN=YES.
In the business parameter i try to add for selecting the particular line in the table control of the PR05 screen, but that doesn't work.
BUS_PARAMETER-KEY = 'PTP1000-MARKER(01)'.
BUS_PARAMETER-VALUE = 'X'.
Insert BUS_PARAMETER into table BUS_PARAMETER_LIST.
CLEAR BUS_PARAMETER.
BUS_PARAMETER-KEY = 'TRIPCHANGEINTERACTIV'.
BUS_PARAMETER-VALUE = 'X'.
Insert BUS_PARAMETER into table BUS_PARAMETER_LIST.
So any inputs on how to auto select the line based on the trip number and go directly to particular change trip.

Hi Alex,
is there no possibility to open the transaction by calling a link? For example like this way:
host, port, system, mandant, user, password, tcode (e.g.: 192.168.100.2:6000:xi?mand=300&user=xyz&passwd=xxx&tcode=se16).
Do anybody other know if there is a possibility doing like this?
Greetings, Alexander

Hi,
The FM might be calling a dialog or bringing a GUI screen up. This would cause the Webdynpro session to disconnect abruptly.
Any conversion exit, GUI screen,dialog popup, transaction handling..etc would cause the webdynpro to disconnect. So you cannot use all FM's as it is.

Hi Ravi,
Just a suggestion.If somehow you crate one more iveiw and add it to the bzcard page then i think you could dispaly both the bizcard and the other wd application on the same ui.
hope this helps.

Whether Workflow Program Exit works in ABAP WebDynpro

Hi,
I have the custom workflow in which in each task i have given a program exit to update the status into my custom tables.
Now i'm in doing the change in workflow, that it should call the abap webdynpro screen, where the user decisions has to be made.
I'm getting the Workitem id from the UWL and then it lauches the Web Dynpro to choose either Approve, Reject or Change etc along with some other travel expense information.
Now once i complete the web dynpro by calling the method 'SAP_WAPI_WORKITEM_COMPLETE', the particular work item is completed.
I want to ask whether before this FM is called,whether the Program Exit which i have written in the Class method and which is called in the Workflow, whether it triggers or not?
Regards,

It is calling the workflow program exit before the SAP_WAPI_WORKITEM_COMPLETE function module.
So closing the thread.
