Folder selection in webdynpro abap

Hi,
I have a requirement to read all the files present in a folder,i have searched for frontend classes but doesnot work in webdynpro abap can any one suggest how to acheve the functionality
Thanks,
Shailaja Ainala.

You have to remember that you are in a Web Browser and therefore are subject to the sandbox security restrictions that the web browser enforces. This means very limited access to the frontend client machine compared to SAPGUI applications.
>I think Thomas Jung has written an e-Learning on this topic, but I believe the premise is that you can use ACFExecute to cause a directory listing to be executed and then ACFUpDownload to download that listing and then download the files.
Its not quite that easy I'm afraid. ACFExecute can't return data to the Web Dypro Application. It is desgined to trigger interactive applicactions not become a data interface between them (although you can pass startup parameters for the application). ACFUpDownload will let you silently upload multiple files (thanks to the use of a Java Applet), but doesn't have any file selection dialog. It was originally designed for KPRO - where you have file check-ins and know the file locations from the document records. A file open/save dialog for ACFUpDownload isn't added until 7.02. Even with the dialog you would still need user interaction to select the files - it can't just read all the files in a directory. Note: both ACFExecute and ACFUpDownload are new in NetWeaver 7.0 Enhancement Package 1.
You could also try a FlashIsland (also new in 7.01). I have a sample of multiple file uploads using Islands as well on SDN. However same issue here - you can't just read the file structure of a directory. Even in Flash/Flex you are somewhat sandboxed - and the user must select the files they wish to upload (although they could select all files in a directory and upload them all at once).
The other solution (which can be done on 7.0) is to have the user manually ZIP the entire directory and then upload the single ZIP file with the normal FileUpload UI element. On the ABAP side you can use CL_ABAP_ZIP to parse and process out the individual files within the ZIP content.

OnSelect event for a Drop down UI Element in Webdynpro ABAP Select Options

Hi Experts
We have built our UI based on the webdynpro ABAP Select Options. We have a requirement that, when we change the value of a drop down box in the UI, I need to hide some fields. Can anybody help me out in handling of OnSelect event of a drop down box built using webdynpro ABAP Select Options. We are on SAP Netweaver 7.0 EHP1.
Rrgards,
Srikanth.
Edited by: Srikanth Kancherla on Apr 29, 2010 10:43 PM

Hi Srikanth,
as you seem to be already aware, the component is dynamically built.
so you would have to enhance the code that builds the element and insert a reference to a new action (enhancement) that could handle the onSelect event.
What is it about this that you particularly want help with?
Cheers,
Chris

Select-options in Webdynpro abap

Hi,
I want to use select options in webdynpro abap ,I checked links available in net but want a simple step by step procedure .
-Sandeep

Hi,
What do you mean by simple steps? You need to write little code to add select options in WDA. You can check this wiki for reference: Web Dynpro ABAP - Complex select-options component usages - Code Gallery - SCN Wiki
And there are lot more documents available in SCN. search here

Default Values for Select-options In Webdynpro-ABAP

Hi Freinds,
Kindly,Help me in setting the Default values for the Select-options in Webdynpro ABAP.
Here the Node and the Attributes are Created Dynamically, and then Displayed Select-options Component View.
Regards,
Xavier.P

Xavier Reddy Penta sent me this question via email and I answered it directly yesterday. Here is the solution that I provided to him, so that it is stored with the original question:
I believe your problem is that you are not setting the value into the range correctly. You are setting it directly into the field symbol of the range like such:
<FS> = L_STRING2.
But ranges are deep objects. They have four fields: Sign, Option, High, and Low. This is from the online help:
1.     sign of type c and length 1. The content of sign determines for every row whether the result of the condition formulated in the column is included or excluded in the entire resulting set for all rows. Evaluable values are "I" for include and "E" for exclude.
2.     option of type c and length 2. option contains the selection option for the condition of the row in form of logical operators. Analyzable operators are "EQ", "NE", "GE", "GT", "LE", "LT", "CP" and "NP" if column high is initial, and "BT", "NB" if column high is not initial. With the options "CP" and "NP", the data type of the columns low and high must be of the data type c, and special rules apply for entries on the selection screen.
3.     low of the data type defined after FOR. This column is designated for the comparison value or the lower interval limitation.
4.     high of the data type defined after FOR. This column is designated for the upper interval limitation.
So when you are moving the value into the field symbol you are setting it into the sign column.
Here is an example of how you can access the components of the range:
* create a range table that consists of this new data element
    lt_range_table =
      wd_this->lv_sel_handler->create_range_table(
           i_typename = l_typename ).
    IF l_fieldname = 'CARRID'.
      FIELD-SYMBOLS: <tab>         TYPE INDEX TABLE,
                         <struct>      TYPE ANY,
                         <wa>          TYPE ANY,
                         <option>      TYPE char2,
                         <sign>        TYPE char1,
                         <high>        TYPE ANY,
                         <low>         TYPE ANY,
                         <wa_values>   TYPE ANY.
      ASSIGN lt_range_table->* TO <tab>.
      APPEND INITIAL LINE TO <tab> ASSIGNING <wa>.
      ASSIGN COMPONENT 'OPTION' OF STRUCTURE <wa> TO <option>.
      ASSIGN COMPONENT 'HIGH' OF STRUCTURE <wa> TO <high>.
      ASSIGN COMPONENT 'LOW' OF STRUCTURE <wa> TO <low>.
      ASSIGN COMPONENT 'SIGN' OF STRUCTURE <wa> TO <sign>.
      <sign> = 'I'.
      <option> = 'EQ'.
      <low> = 'AA'.
    ENDIF.

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` ).

Issue on Creating RFx in webdynpro ABAP application - SRM Business Package

Hi
We are in to SRM 7.0 with the same version of Business Package in SAP Portal also.
I am trying to create a RFx from Portal which in turn calls the webdynpro ABAP application (Strategic Purchasing->Strategic Sourcing->Create Documents->RFx)
sap/bc/webdynpro/sapsrm/wda_l_fpm_oif.
This Application has some button called "Tech RFx", "Permissions" etc., When I click on those buttons it throws the error as below :
"There is no iView available for system "SAP_SRM": object "TechResp". For more information, contact your administrator."
Please let me know where we are missing. I have checked all the Portal permissions. Even I can able to access all other iviews except this two buttons.
Any settings or parameters required on webdynpro ABAP side.
Regards,
Raja.J

Dear Raja,
this behavior occurs if the IView com.sap.pct.srm.gp.iv_tech_resp
is not assigned to the role which is assigned to the user.
Please assign this IView to the desired user.
Here are the steps to follow in your systems:
STEP 1: Login to the Portal with Content Admin Authorization.
STEP 2: Navigate to Portal Content -> Content Provided by SAP ->
specialist -> SRM7.0 -> Core -> Roles -> Open the desired role and
choose Navigation Folder.
STEP 3: Now navigate to Portal Content -> Content Provided by SAP ->
specialist -> SRM7.0 -> PPS -> iViews -> Tendering -> Select Tech
Responses (Technical name is iView com.sap.pct.srm.gp.iv_tech_resp) and
right click and choose 'Add iView to Role' -> Delta Link and save.
STEP 4: Log off and login with the user and check the issue.
Best regards,
Tamas

How to Generate New Version of Enhancements done to Std WebDynpro ABAP obj

Hi Experts,
We have enhanced a SAP Std WebDynpro ABAP component (HAP_DOCUMENT_BODY) using Enhancement framework provided by SAP. Multiple enhancements were done on the same component for different requirements. Now, under the Enhancement Implementations folder of this component, you can see 5 enhancements of the component each referring to the 5 different changes done (most of the changes were done to the same view ).
These changes has now been transported to the Quality System. Now, the client wants one of the changes to be removed. I am not sure of the impact of removing, for eg: the 3rd enhancement, on the other changes done as multiple enhancements were done in a mixed manner.
What i want to do is to generate a new version of WebDynpro component on Dev which has all the enhancements done so far using Utilities -> Versions -> Generate new version. Then try to delete the 3rd enhancement folder, so that if something goes wrong, I can always revert to this newly created version on DEV which has all changes available.
Questions:
1) Before that, I would like to know if I can generate versions of the enhancements done of WebDynpro ABAP using enhancement framework by using Utilities -> Versions -> Generate new version ?
2) If yes, I want to generate one version which has all the enhancements done so far using enhancement framework. For doing so, where should i do the click or selection (Is it Std Main Component or is it Enhancements in the enhancements folder-if so, there are 5 of them, and which one??) before i go to Utilities -> Versions -> Generate new version. I am not clear where i should select or keep the cursor selected on before generating a new version?
Please guide with step by step details.
Thanks,

I have moved this post to the HTML5 layouts forum, which is more appropriate.
I am guessing you are using Rh11 as you have a trial copy. I have some instructions for Rh10 and the only difference should be the script used. See the contact page on my site and request those details. Include a link to this thread.

Portal Theme in Webdynpro ABAP

Hi Experts,
I want my portal theme to get applied to the webdynpro abap application.But WDA application is not adapting the portal theme.
This is the version of the theme's style sheet in portal=7.1.3.0.1;ur=7.1.3.0.1;7.1.3.0.0(Major version.minor version.SP.patch.generation run)
The version of Webdynpro abap theme is 7.11.3.2.0.
Portal Version is NetWeaver 7.0 Ehp1
and SAP Basis Version is 701 and level 5.
Is there version incompatibility?
How can I solve this.
Thanks and Regards
M.Karthiheyan.

Hi M.Karthiheyan,
Please follow below steps to apply Portal theme in Webdynpro ABAP.
1. Go to transaction SE80 and navigate to the MIME Repository
2. Create a folder in the MIME repository that will contain all the custom theme files. Make sure the folder is created in following directory /SAP/PUBLIC/BC/UR/<theme_name>
3. Go to the Repository browser in SE80 and select u201CProgramsu201D from the drop down list.
4. Enter BSP_UPDATE_MIMEREPOS in the input field and hit Enter
5. Execute the program and enter the MIME repository path to the folder that is to contain the custom theme. Our custom theme is located in MIME path /SAP/PUBLIC/BC/UR/<Theme Name>
6. Execute the program and select root folder that contains all the custom theme files. The custom theme can be directly pulled down from the file server on portal or can be exported from Portal Theme Editor and imported into Eclipse Theme Editor in order to generate the necessary css files. We only need the root folder that contains the actual css files and images. The upload process might take a while depending on the size.
7. Once the upload is complete, go back to the MIME Repository and check if the files were uploaded.
8. To specify a theme at the global level you can execute WebDynpro component WD_GLOBAL_SETTING. Maintain parameter u2018Stylesheet URIu2019 with the MIME Repository path of the custom theme (i.e. /SAP/PUBLIC/BC/UR/<custom_theme>).
9. Enter the path under "Stylesheet URI:" and select the check box which says "Force use of External Stylesheet".
Thanks.

Portal application parameters for webdynpro ABAP

I have read several posts that indicate we can get the portal user login id in WDA by adding:
userid=<User.LogonUid> to the application parameter property in the portal iview, and then adding a corresponding parameter in the Webdynpro ABAP method HANDLEDEFAULT of the Window.
I'd like to know if there are other such system parameters (besides <User.LogonUid>) that one can pass from Portal to a Webdynpro? A list of such parameters, or a link to such a list would be very helpful.
Best regards,
Tarun

Hi,
In the Portal,

Webdynpro ABAP export/import

Hi,
I have create a webdynpro application with SAP Netweaver 2004s an I will use this application on a portal with SAP Netweaver 2004.
How can I get the files in the other system?
Can I do this with download/upload or transport ?

Hi Klaus,
So you have created a WebDynpro ABAP Application using the SAP NW-Dev Studio.
-o I suppose you can export the complete the WebDynpro Application as Jar File / Zip File etc. This for Backup.
-o To make it show itself on a SAP Portal, you have register the WAS Server(your SDM where you deployed your application).
-o Nextly you can transport your WebDynpro Appl by doing
--oo open your SAP Portal :: like sapsrvr://test:50400/irj/portal
--oo next login and click on the Content Administration, you would see below a list of tabs like Portal Content, Multiple
Property Replacement ... and also Web Dynpro.
--oo Now click on Portal Content
--oo Go to Browse tab below
--oo Select your folder (where you want to show ur application)
     ---ooo Right click on it and select new -> iView
     ---ooo Select 'SAP Web Dynpro iView' from radio buttons and click Next
        ---ooo Enter a name , id of the iView ( they can be same, dont enter white spaces between words), click next
     ---ooo Select ABAP or Java ( in ur case ABAP)
     ---ooo Enter all the values like namespace, application name of ur application ( u can find them when u run the
WebDynpro ABAP application, like local/WebTut_UI and WEb_UI respectively)
     ---ooo save it and see the summary
now you must be able to see your application as an iView in the Portal Application.
Please do let us know if you could solve your problem or if you need any other information / Clarification.

Webdynpro ABAP content authorization object in SAP portal ?

Hi
We are on EHP 6.06 , we have an authorization problem in sap portal for the webdynpro abap content. our standart users got the error "page can not be found" for the services provided from webdynpro abap. when I assign the user to administrator group in sap portal the services working fine. I also checked the SAP ERP roles no problem is there. I guess I should create a new portal role for them cause its the only difference between users who can reach or not but have no idea what to put in it in SAP portal. Any idea ?

in portal content directory => double click on the Content provided by sap folder. Than you should have a dropdown somewhere where you can select "Authorizations". You should add the group endusers and check the checkbox.
