Mass upload & Download of PDFs in Web Dynpro ABAP

Hi All,
Is it possible to download multiple PDF's at one go ? for example if you have a Table UI control where each row has one clickable link that generates a PDF using WebDynpro ABAP Application, we want to enable multiselect property of Table UI and provide Mass Download Button control on click of which all selected rows should generate PDF and then get dowloaded to a specific location on machine (c:/). or if there is any other alternative possible ?similarly for Mass Upload we wish to multi select PDFs and upload them to R/3 at one go ?
please let me know if such thing is possible ? if yes is it a good option to have ? as we have users who have to upload these PDF one by one and they wish if they could simply select all PDFs at one go and click Mass upload..Note that there are some validation that we perform once we upload PDF before posting PDF data to backend.
your help & comments would be Highly Appreciated !!
Thanks
Asif

You simply use the CL_ABAP_ZIP class to combine the multiple binary strings of the word files together.
data izip type ref to cl_abap_zip.
data zip_xstring type xstring.
create object izip.
loop at ifiles assigning <Wa_file>.
izip->add( name = <wa_file>-filename
content = <wa_file>-filecontent ).
endloop.
zip_xstring = izip->save( ).

Upload a .xls file in web dynpro abap

Hello,
I want to upload a .xls file into a internal table in web dynpro abap (Netweaver 7.31).
The file is not delimited, is not an csv file.
In my view I have an fileUpload UI Element with the attribute data is un attribute type XSTRING and the following function module are not in my system:
HR_KR_XSTRING_TO_STRING
ALSM_EXCEL_TO_INTERNAL_TABLE
How can I upload the file with this format?.
Thanks in advance.
Xavi

Unless the files are zipped together into one archive file, you have to do them one at a time. Furthermore with the normal browser based fileUpload UI element, you must do them one at a time and the user must manually select each one (browser security limitation).
If you are on 7.01 you can use ACFUpDown to perform multiple file uploads, but there is no file dialog or directory scan so file selection is difficult.
If you are on 7.02 you can use ACFUpdown and it has a multiple file open/save dialog.
If you are on 7.01 you could use FlashIslands to perform the multiple file upload. I have a tutorial and source code sample for this on SCN.
If you are on 7.01 you could also use ACFExecute to run a batch script on the client side that zips all the files and then upload the zip archive.

Upload file into KM using Web Dynpro ABAP

Hi, I'm looking at converting an existing Web Dynpro Java application to a Web Dynpro ABAP application. However, I cannot find how to upload a file and store it in the Portal KM repository using WDA. I have been able to do it successfully using WDJ. Any help on how to do this would be very much appreciated. Thanks.

The connection test in SM59 only does a basic PING to the web service endpoint. Often it will show OK, when in fact the ADS is not setup correctly. That is why there are some test applications that do more.
For proper testing of your setup see OSS Note 944221. But basically run the ABAP programs FP_PDF_TEST_00 and FP_CHECK_DESTINATION_SERVICE. You can also try running the web dynpro components WDR_TEST_ADOBE and WDR_TEST_ADOBE_PDF_ONLY

How to display smartform as PDF in web dynpro java

Hi,
Where can I find sample program to display smartform as PDF in web dynpro java.
Thanks.
Regards,
Henry

1. Create a smart form in the R/3 side
2. Now create a function module with the corresponding export parameter:
3. Make sure that the function module is marked remote enabled.
4. In NWDS create an Adaptive RFC model which points to the FM created in R/3 under the webdynpro application
5. Now create an application and view inside it to display the PDF and Insert a frame inside the view
6. Create a value node and an attribute say url of type string inside that node and bind it to the source
7. In the doInit() method place the following code
>    ZTest_Pdf_1_Input input = new ZTest_Pdf_Input();
>    wdContext.nodeZTest_Pdf_Input().bind(input);
>    try {
>            wdContext.currentZTest_Pdf_InputElement().modelObject().execute();
>            }
> catch (Exception e) {
>                        e.printStackTrace();
>            }
> wdContext.currentInternalElement().setUrl(convert(wdContext.currentOutputElement().getBin_File()));
Inside that view create a method to convert the string to url so that it can be passed as a string to the setUrl method of the currentContextElement() , say convet(byte[] doc_content) which return a string.
Inside that methos write the following code,
>         String url = "";
>           WDWebResourceType webResType = WDWebResourceType.PDF;
>            IWDWebResource webResource = WDWebResource.getWebResource(doc_content, webResType);
>            try {
>                        url = webResource.getURL();
>            }
> catch (Exception e) {
>                        e.printStackTrace();
>            }
>            return url;
Hope It will be helpful

Is there a way to get Web Dynpro ABAP available in a ECC 5 - NW2004 env?

We will start developing an offline Adobe interactive form with email functionality for ECC 5 on very short terms. We have to decide asap what client/server configuration we will use for this new functionality. We will also develop an online interactive form and an offline form with upload/download functionality for ECC 5. We will have to setup a client/server configuration that supports all 3 scenario's.
The main reason we would like to have NW2004S available for ECC 5 is because we would like to develop the forms in Web Dynpro ABAP instead of Java. Guided Procedures is a "nice to have" too, but not really important at this moment.
At this moment we think we have 3 options:
1. Investigate if we can make an Adobe solution in WDA for ECC 5 with our current setup
2. Upgrade ECC 5 - NW 2004 -> NW 2004S to get WDA functionality available
3. Install ADS for NW 2004 to be able to create Adobe solutions in ECC 5, then we will have to develop in WDJ
1. We have the following configuration up and running: NW2004S - CRM 5 and ADS installed: both Java and ABAP stack work properly. We are wondering if we could develop an Adobe interactive form in Web Dynpro ABAP in CRM 5 using BAPI's to retrieve the data from ECC 5 and put it on the form for display or update purposes. Also we have questions about the email functionality: do forms have to be send by email via a mailserver from ECC 5 via CRM 5 and back or can this be done directly from and to ECC 5 or is it not possible at all? Also we don't know if we can develop an online interactive form for ECC 5 via CRM 5. The current setup is not a real option for us right now as we see far too many uncertainties. Does somebody can give us some answers on the possibilities we are looking for?
2. My assumption is that upgrading ECC5 to ECC6 can be compared with upgrading 46C to ECC5. If my assumption is correct, this would mean an upgrade project with a 6 months leadtime within our company. If my assumption is wrong, please let me know. This upgrade will happen some day, but it has not been planned for 2007. So unfortunately, for us this is not an option at the moment because we cannot wait that long. I was hoping an upgrade of NW2004 -> NW2004s was not that time consuming but I guess this can be compared with a SAP upgrade project like 46C -> ECC 5.
3. Installing Adobe Document Services for NW2004 is not our preferred solution but we think it is the safest/easiest solution at this moment to get started with Adobe interactive forms for ECC 5 on short terms. We will have to develop in Web Dynpro for Java, so be it.
WDA is not a must but if we can find a client/server setup which gives us the possibility to build in WDA for ECC 5 functionality, that would be great. That's why I dropped the question on SDN. I want to be sure we choose the best option possible at this moment for us.
kind regards
Angelique

Yesterday I got new information through SDN which sounds very interesting:
There are technical repository integration points between ECC and the underlying SAP NetWeaver release. To get Web Dynpro for ABAP, you could install a stand-alone SAP NetWeaver 2004s system (without ERP) side-by-side.
Somebody else wrote: we set up a 3-system landscape of NW04s and have configured single sign on and trusted RFC's so that users can hit the webdynpro pages via the portal, and those systems make the necessary queries to the backend systems via RFC.
Does somebody know if this stand-alone system could be a proper solution for our situation? Does somebody foresee any problems related to Adobe LiveCycleDesigner or ADS?

Display file content in Web Dynpro ABAP

Hello,
we would like to be able to display any file after having uploaded files using FileUpload ui element in a web dynpro abap application.
for microsoft word excel files, the OfficeControl ui element can be used and for pdf documents the InteractiveForm ui element can be used.
for other formats such as '.tif', '.jpg', '.txt'..... we did not find out how to be able to display the file contents
Does anybody know if and how this could be achieved?
Cheers
Ana

Chris,
You may be right. Also it requires some configuration in SAP KPro ( document class etc).

How to call custom themes for Web Dynpro ABAP Application?

Hi,
I need to change the appearance of Web Dynpro ABAP application. So far I followed below steps,
1.     Created theme folder u2018testngou2019 (SE80->MIME Repositoty -> SAP->PUBLIC->BC->UR->nw5->themes -> u2018testngou2019 ).
2.     used program BSP_UPDATE_MIMEREPOS to dowmloaod content of u2018sap_tradeshowu2019 (SE80->MIME Repositoty -> SAP->PUBLIC->BC->UR->nw5->themes -> sap_tradeshowu2019) to desktop.
3.     Modified the themes using Eclipse Theme Editor.
4.     used program BSP_UPDATE_MIMEREPOS to upload modified themes to MIME repository u2018testngou2019 (SE80->MIME Repositoty -> SAP->PUBLIC->BC->UR->nw5->themes -> u2018testngou2019) .
My current URL is like http://server.name:XXXX/sap/bc/webdynpro/sap/hrrcf_a_startpage_int_cand?sap-client=XXX.
Now I want to know how custom themes called for Web Dynpro ABAP Application.
Is my approach correct?
...Naddy

Hi Naddy,
What you used is one way and even I failed when tried that method,
Instead go to SE38 - WD_THEMES - and you need to upload the zip file and you need to follow a folder structure.
it is case sensitive, atleast the zip file.
Make a zip file by name "Project.zip" -
Create a Folder Project and have the below folder structure,
1 data - all the properties files and also the designinfo file, below is the code
2 themes - (to get all the files download the theme from portal and you will have all the folders)
   2.1 ur
     2.1.1 name of the theme
       2.1.1.1 common
       2.1.1.2 csf
       2.1.1.3 r
       2.1.1.4 ur - all the css files (would be good if you can get the files from the server.)
       2.1.1.5   WSRP
3 war - empty folder
*.designinfo
isVisible=true
version=7.0.14.1.0
isDefault=false
isSapDesign=false
designName=**** name of the theme
Once done create a zip file and click on Start Import and give the path and will ask for transport request, it will take a while to upload once done as mentioned in the use the parameter sap-ep-themeroot="path"
This will resolve the issue.
Cheers-
Pramod

As the name suggests Web Dynpro for ABAP uses exactly the same meta model as its cousin Web Dynpro for Java. A Web Dynpro component, a Web Dynpro view, a Web Dynpro model, a Web Dynpro controller have the same semantics both for ABAP and Java. The main difference is the designtime environment, the development infrastructure and the runtime environment.
The designtime environment is properly embedded in the ABAP Workbench where Web Dynpro artifacts are simply a new category like BSP applications or classical dynpro based applications before. Also no surprises regarding the development infrastructure. The correction and transport system keeps track on all changes that are done, versions them and helps to propagate the Web Dynpro application from development to production like you would do with ordinary BSP or dynpro-based applications.
Last not least the execution platform is the ABAP server that produces application content ready to be integrated in the NetWeaver Portal seamlessly. Features like portal eventing can be used between applications written in ABAP or applications developed with Java.
First of all start doing SAP SDN tutorials .

Try to Download demo tutorials from SDN library & Try to search WebDynpro ABAP WebLogs .
Wait not just that SAP has provided you with ample demo example of WD ABAP already bundled with SAP . Just Try out Components starting with WDR . I can tell you few like WDR_TEST_EVENTS ( It shows how every UI elments to use )
See packages like SWDP_DEMO , SALV_WD_DEMO
there are many more .

If you need some standard examples then do WDR* and you'll get a big list in se80 transaction. Also SWDP_DEMO is a good package to refer to. Check for WDR_TEST_UI_ELEMENTS and WDR_TEST_EVENTS for UI operations and their various events.
1) This is basic Info of WD ABAP
As the name suggests Web Dynpro for ABAP uses exactly the same meta model as its cousin Web Dynpro for Java. A Web Dynpro component, a Web Dynpro view, a Web Dynpro model, a Web Dynpro controller have the same semantics both for ABAP and Java. The main difference is the designtime environment, the development infrastructure and the runtime environment.
The designtime environment is properly embedded in the ABAP Workbench where Web Dynpro artifacts are simply a new category like BSP applications or classical dynpro based applications before. Also no surprises regarding the development infrastructure. The correction and transport system keeps track on all changes that are done, versions them and helps to propagate the Web Dynpro application from development to production like you would do with ordinary BSP or dynpro-based applications.
Last not least the execution platform is the ABAP server that produces application content ready to be integrated in the NetWeaver Portal seamlessly. Features like portal eventing can be used between applications written in ABAP or applications developed with Java.

Integrating Web Dynpro ABAP application in portal

Dear experts,
I created a Web Dynpro ABAP application. I need to Integrate it in portal and have to capture portal login id to my application.
Kindly guide me how to integrate WDA in portal and how to capture Portal Logon id in my application.
Thanks,
Kind Regards,
Ram

Hello ,
It is asking for SAP system user id and password becasue there is no SSO established between portal and the web dynpro system.
Now, either you can establish SSO between portal and the backend system by SAP Logon TIcket or user mapping.
SSO stands for single sign on.
SSO using SAP Logon Tickets :-
by using this technique you will be able to login into the backend by using SAP logon ticket
issued by the portal system. For this you need to import the .der certificate form the system administration ->system config -->
key ticket store. there download verify.der and upload it in the trusted system list in the backend in the trasaction strust_import.
here is link for this method.
http://wiki.sdn.sap.com/wiki/display/EP/LogonTickets,CertificatesandBackend+Certificates.
SSO using user mapping. :-
For this method you need to map the user in the portal to one user in the backend system.
You can do so by going to user administration in the portal there find the user id with which the user will login.
then go to the user mapping for system access tab there select the system from the dropdown and give user id and password
for the same system save it.
Now when you will login it wont ask for the user id and password.
And after this you can get the portal user id also in your web dynpro application.
Thanks

EREC: theme for Web Dynpro ABAP pages (external candidate)

Hello,
I have created a custom theme in the SAP Netweaver Portal for my customer and now I have the requirement to use the same theme for my stand-alone Web Dynpro ABAP applications (pages for the external candidate). Is it possible to use the same stylesheet as in the portal, without having to recreate a theme?
I tried several options, but none of them did work:
A. Downloading the portal theme as a ZIP file and then uploading it in ERP using the report BSP_UPDATE_MIMEREPOS (after unzipping) to a location /SAP/PUBLIC/BC/UR/nw5/themes/CUSTOM_THEME. After that, I call my application with the additional URL parameter sap-wd-themeroot=/SAP/PUBLIC/BC/UR/nw5/themes/CUSTOM_THEME but it does not work (the app is displayed with the default sap_tradeshow stylesheet)
B. I also tried calling my app using the URL parameter sap-cssurl=/SAP/PUBLIC/BC/UR/nw5/themes/CUSTOM_THEME but here again, it does not work (the app is displayed with the default sap_tradeshow stylesheet)
C. Downloading the portal theme as a ZIP file and then uploading it (zipped) using the report WD_THEMES, but here I receive the error "no themes found in the ZIP file". I have the same error if I upload only the ur.zip I receive from the portal (instead of uploading the whole *.zip file)
I checked the UR versions both in portal & ERP, and we had a lower version in the portal than in the ERP, so we upgraded the portal version according to SAP note 1446099. Now we have a higher version in the portal than in the ERP. We regenrated the portal theme and downloaded it again, but with the same result.
Does anyone have an idea what could be the solution to our problem?
Thanks in advance!

I would recommend to try another way. If it is possible to access any SAP Portal from outside you can use two URL Parameters to integrate the Portal style sheets in a standalone WDA application. The parameter sap-cssurl contains the absolute URL address to the style sheet and parameter sap-cssversion the current SAP Portal style sheet version. For all external facing scenarios it is important to use the whitelist mechanism to block unknown URLs.
Example
?sap-cssurl=http://myportal.myserver.com:50000/irj/portalapps/com.sap.portal.design.urdesigndata/themes/portal/mytheme/ur/ur_ie6.css
&sap-cssversion=7.11.5.20.0
I canu2019t recommend to raise manually the version number. You will not get an consistent system this way. The meta data (project.zip) are outdated and of course you will get an outdated theme.
