Starting Webdynpro ABAP development

Dear Experts,
I am a Portal Consultant and I know Webdynpro Java. I am planning to learn Webdynpro ABAP.
Could you please provide me the details about actual Webdynpro ABAP development?
I have seen some applications and they used "Service Call" method to execute BAPI's and setting Import parameters.
In some applications they used normal development.
Could you please provide which is suitable( through Service call or normal development) and majarity of the people can use?
Thanks & Regards,
Vijay

Hi Vijay,
Service call is required basically to get data from systems other than the calling systems i.e. a RFC call. Though you can use BAPI's to get data from the same system. (FM must be RFC enabled to use this functionality)
You can also call normal FM, but for that you don't have to create a service call.
Suppose if you want to use some standard BAPI's or FM just by creating service call you can use in your application.
check this example how to use BAPI,

Dear Friends,
We are facing a serious problem for debugging. Expecting valuable input for the same.
Debugging is not working in R/3 from WebDynpro-ABAP developed webpage input in Production Server.
The debugging (for WebDynpro-ABAP application) is working in Dev. Server for
1st ] Within R/3
Ex. debug for bapi within R/3. i.e. value enter as input in R/3 only.
2nd ] From webpage to R/3
Ex. Some input given on the internet web page developed through WebDynpro and external breakpoint set in R/3 it works. It directs to R/3 code through debugging.
In Prod. Server the 1st case above is working but the 2nd case is not working.
In Prod. Server the WebDynpro developed applications are running successfully through internet explorer webpage inputs. So running the application is not a problem in prod. Server but debugging of the same is the problem.
The setting which are done in Prod. server are,
1] RZ10 in parameters are set for port and host name.
2.1] In SMICM check for ICM.
2.2] Host file updated in Windows-System 32.
3] In SICF following services are active,

Standard Transaction Vs Webdynpro ABAP development in Portal ?

Hi All ,
I just need to know that if we do some kind of enhancement/modification in sap standard screen using the classical tools like screen painter etc. when we deploy these transaction on portal we will have those changes on the web based GUI or we need to developed the whole new development for that transaction to show on the portal ?. I know webdynpro for ABAP can be used for new developments but what if we just need a simple change on screen and we can achieve the goal using simple screen enhancement ? do we need to develop the screen again in webdynpro ? Kindly can anybody explain this ?
Thanks a lot in advance.
Laeeq.

SAP ABAP screens are used by SAPGUI for Windows and SAPGUI for HTML and are presented exactly as the screen designer lays them out. The portal can start either SAPGUI variant.
WebDynpro has nothing to do with existing SAP ABAP screens. You build new screens and then call BAPIs etc to populate the fields.
The portal can start a Web Dynpro application.
To change the look of an existing SAP ABAP screen you need to change the screen. If you want to completely change the screen, start building Web Dynpro programs.
Cheers

Getting started to WebDynpro ABAP

Hi All,
I am new to this, i have got developer's Studio Installed and ECC 5.0 IDES installed in my system, is that enough for starting WebDynpro ABAP.
If no, then can anyone kindly tell me, from where i can get the necessary resources?
Regards
Siddhartha Sengupta

Hello Siddharth,
You dont need to have developer studio for webdynpro abap.
I am not sure if ECC 5.0 has webdynpro,, but positive that it should have...
Goto SE80 and in the repository browser check if you have webdypro component/interface option...along with others like package, class/interface etc...
if it there, then ur system has webdynpro abap and u can continue there.
Thanks,
Anand

Launching webdynpro ABAP application from workflow task (without UWL)

Hello,
How can i start webdynpro ABAP application from workflow without portal?
Workflow and webdynpro ABAP are located on the same system.
I assume it must be possible without transaction SWFVISU.
thanks
Regards
Paul

First you need to define a external service then you have to generate a task from this external service and then you need to include this task id in you workflow for a ACTIVITY step then this step can be either background or can be assigned to any agent
you have to make use the below two Txn
WF_HANDCUST and WF_EXTSRV

Start both Webdynpro JAVA and WebDynpro ABAP from UWL

Hi all:
We are facing a situation. We need to start both JAVA dynpro and ABAP dynpro applicaiton from uwl. The JAVA dynpro application is the ESS absense request. And we also developed other workflow which use ABAP dynpro as work item . The problem is when we regist our ECC system to UWL, the system can only provide WAS java information or WAS ABAP. So there are alway one type of our work items can't start correctlly. How can I modify the UWL configuration to meet our requirement?
Anyone knows please notify, thank you very much!
Wayne

Hi,
when you try to register backend system , you will choose system alias which was already existing in the portal which has WAS hostname and port.
that is sufficient. Based on visualzation parameters , you can launch webdynpro abap/java tasks.
check below article

When to use webdynpro for developing reports instead of ABAP Editor in R/3

Hello Frends,
I am new to Webdynpro ABAP. I just wanted to know when we should used webdnpro ABAP for developing reports, instead of using ABAP Editor in R/3. If you can give me the details it will be helpful.
Thanks,
Regards.

Hi navnetha,
As mishbah told you , that there is no hard and fast rule for reporting throught webdynpro.It all depends on client requirement .Now if you want to develope alll the reports by using webdynpro without your clients request , then you need to explain the advantages of webdynpro reporting above abap reporting.
for e.g. Webdynpro reports can run on browser, They can be posted on portal, Easy handling and maintenance and reusability.
Other than this i guess if you can show some business profit to the client, then i think every client would like to go for webdynpro reporting.

Begin a SAP career starting as ABAP IV developer

Hello,
Soon I want to start a course in ABAP IV, with the aim to get certified in the medium term. I've played some SAP, and I think it could like me much.
Anyway, I would like to make a career in SAP world, beginning as ABAP developer as IT professional I am. But in large term, I would like to get specialized in any module. So, I would ask you if this is a real possibility, or being an ABAP developer, you get stuck the professional career as ABAP developer.
Being IT, which module can I opt for?, Only BASIS?, or also can I opt for modules like BI, FI, Sales, .. without having studied something related with management and business administration?
Regards and thanks in advance from a newbie.

Luis,
"getting suck in the same module"....
Let me give you a parallel example, generally an actor gets similar roles based on his past (successful) performances. Breaking into different roles is difficult.
It all comes down to that particular actor - his desire, talent and hardwork.
So, there is no set answer. It all depends upon an individual and his luck.
Good luck!

ECC 6.0 Webdynpro for ABAP development environment

Hello,
We are currently running ECC 5.0 and ABAP stack is only available as of ECC 6.0. Is is possible to download and install just ECC 6.0 development environment?
Thanks,
Alex

The ABAP development environement and runtime are integrated into the Business Suite release. Therefore ECC 5.0 runs on top of NetWeaver 2004 (6.40) and ECC 6.0 runs on top of NetWeaver 7.0. There is no way to directly mix ECC/NetWeaver releases nor can you directly transport NetWeaver 7.0 objects (like Web Dynpro ABAP) to a 6.40 based system since the runtime wouldn't be present.
You can however install a standalone NetWeaver Systems. Then you would have a separate instance with the ABAP 7.0 developement and runtime environement. You can use RFCs and Web Service Calls from this standalone system to read and write data to/from your ECC 5.0 system. You give up some of the benefits (like the integrated DDic value-help).

Create PMD (Clinical Document) Document from Webdynpro ABAP

Greetings everyone,
I have developed two PMD document category(Tcode :N2T6 ) for Clinical documents in SAP R/3 and somehow with the limitation of R/3 in terms of developing user friendly screens like Auto fill and image processing etc...,Users do not satisfy with it.So we are planning to develop in Webdynpro ABAP.But i am not sure how do we integrate the webdynpro development with IS-H PMD (clinical documents) documents ,also I am looking for BAPI's to create our customized parameterized documents.Any help will be really appreciated.
Thanks,
Vignesh

Hi Vignesh,
You are right that certain features, such as auto-completion, are not supported in the PMD toolset. But as most of the data captured in those documents have a high importance for treatment process, you need to elobarate whether such a feature has any impact on patient safety. Just a quick one - user types An ... and the system determines matching diagnoses such Anorexia or Angina. In case the user picks the wrong one by accident the patient safety is an issue.
Other features such as image management can be used. For that you need to use a PMD link module which does provide the image integration. Siemens will ship in the next release EhP6 such a link module for a third party imaging software. Beforehand the link module use with custom development.
In general Siemens has started a product redesign program named "Smart UI". It's major aim is to provide an up-to-date user interface for all major application within i.s.h.med. The very first application we plan to ship is a web-based electronical medical record.
In case you still want to develop your application, I'm sorry to say, but there are no BAPIs or Web services in the standard delivery. For changes to existing documents you can utilize the PMD API of generator version 2. But be aware that document creation is not supported by the API. You need to have a document. Also certain user exit developments may brake a change without having the GUI running. For instance a popup in the save routine will cause a dump if no SAP GUI is available.
Hope this help.

WebDynpro ABAP for our MM Processes

We are going to implement WebDynpro ABAP for our MM Processes starting with ME21N screen. We are going to select some specific fields from those screens and customize our portals so it will be easy on the end user(Ex:Buyers do not want to see all the fields in ME21N). if you have any bad/good experience with implementing above process please share with me.
Thank you,
Raneetha.

Hi Raneetha,
I have not done any such scenario but I see it as a feasible development.
One thing that matters is that : Are you creating the Web Dynpro components on the same system on which your MM is?
In case they are different then you need to analyse the data transfers between two systems and the performance delays henceforth.
Please revert in case of queries/doubts.

Sumit

SAP HANA development languages for ABAP Developer

Hi I was just looking at some blogs on HANA. Can anyone tell me how to learn the new HANA programming languages SQLScript etc. As you know not many companies use HANA yet, so getting to use a real HANA box can be hard as of now.. What are the other options... Can I install the HANA software on my PC and use it with a few Excel files or MS-Access db just to workout what these programming languages actually do.. Ofcourse I dont have access to the HANA box(hardware that SAP talks about). I am an ABAP Developer I have access to ECC if that helps.
Also from what I can understand the HANA box sits on top of the ECC/BW systems etc or would HANA replace some aspects of the Application Server and sit in the R3 architecture? if the second scenario is true would most of the ABAP reports etc written using traditional ABAP have to be replaced or modified to use HANA related code in them to improve performance(I know ABAP doesnt support this yet).
If companies start using HANA I would think most ABAP developments just querying to get data would need to be rewritten-even the webdynpro applications for performance.
Can HANA update DBs as well?
Would HANA programming be a required skill for most ABAP developers in future?

Hello Sk,
so far (with HANA 1.0 SPS 2), the only relevant languages to learn is SQL and SQL Script. Check http://service.sap.com/hana which has SQL and SQL Script Guides.
Since you know ABAP already, you will pick these things up rather quickly. There are as you noted some concepts you have to understand in order to make optimal use of the HANA features and get maximum performance (anyone could come up with SQL or SQL script that crawls to a halt even in HANA). One key is to process everything is sets of data rather than record by record. Another important item is to keep all processing within the column engine. Also avoid joins that lead to large intermediate results. We are currently writing some how-to guides which will be publised on http://www.experiencesaphana.com/. Stay tuned!
In terms of the architecture, I would say HANA as a database sits below the application server and/or client, for example, BW powered by HANA where HANA plays the role of the DBMS. The other option is to run side-by-side for example, connecting HANA to an existing ECC (that runs on MS-SQL). In either case, you are right; the logic (either in the application on top of HANA, or the models inside HANA) needs to be changed or created to take advantage of HANA.
Where can you learn more? Class room training TZHANA or come back regularly to the Try section of the Experience Site where we plan to publish other options.
Regards,
Marc
SAP Customer Solution Adoption (CSA)
PS: And we certainly have plans to integrate HANA features into ABAP
