Hi Ravi,
The following are basic differences between ABAP and JAVA WD.
1. ABAP WD can be developed in ABAP Workbench thru transaction SE80 whereas Java WD needs SAP NetWeaver Developer Studio.
2. Since ABAP WD is a part of the ABAP Workbench, it has direct access to ABAP dictionary. Hence access is faster.
3. In order to develop on ABAP WD, you will need basic knowledge of ABAP objects, whereas in Java WD, dev is using Java

Hi,
Step step description here is not possible.
It always advisable to go to service.sap.com/instguides.
slow and steady wins the race.
good luck.
It's advisable to have quad processor with atleast 8GB ram.
If it's a nw04s then at a shot you can select AS ABAP. JAVA, EP, PI(XI) and proceed.
hope this helps you.

Web dynpro abap or java ?

Hi All,
Our client wants a web front end for the SAP system and has asked us to search which web dynpro ABAP or Java will be suitale ?
They were of the opinion that web dynpro for ABAP is not that good for web interfaces is it correct ?Also is there demend for web dynpro developers in the market ?
Thanks & Regards
Gaurav Jain

>They were of the opinion that web dynpro for ABAP is not that good for web interfaces is it correct ?
What do you mean by Web Interfaces? Web Dynpro ABAP and Java are well suited for created browser-based (or rich client based) business application User Interfaces. If by Web Interfaces you mean Internet facing, highly customizable user interfaces - then no - neither web dynpro abap or java are really well suited for that situation. WDA and WDJ are both designed to create consistent Business Application user interfaces.
Now if you just want to compare WDA and WDJ - that is a very different question. The differences in capabilities are relatively minor. Generally it comes down to which programming language you have more of a skill set in and how close to the underlying data you need to be. Also are you planning to extend existing SAP applications? WDA is primarily used by SAP within the Business Suite (ERP, SRM, PLM, etc) - two exceptions however - WDJ is used in ESS/MSS (although newer portions of that solution are in WDA) and CRM uses BSP/CRMUI. WDJ is used by the middleware components (Portal) and edge or composite applications.

Authorization objects in web dynpro ABAP and SU24 transaction

Hi,
I have created a new authorization object to check a storage location for certain activities. I have added the authorization object in a specific web dynpro ABAP and I have created a new role in PFCG for my web dynpro ABAP.
The organization level for storage location is not recognized in PFCG. Someone told me I have to maintain my authorization object in SU24 as it is done for transaction.
I wanted to maintain my web dynpro in SU24 but I found no way to do that.
It seems that we can maintain authorization for TADIR service and in those services there is R3TR WDYA but when I use the search help for OBJ_NAME I don't find may web dynpro ABAP. I suppose I have to create a TADIR service for my web dynpro ABAP or something like that but I don't know how to do ?
Does anybody know how to deal with specific authorization in web dynpro ABAP and t ohave the organizational level recognized in PFCG.
Thanks for your help,
Emmanuel

Hi,
Please RUN the function module as "AUTH_TRACE_WRITE_USOBHASH" with following parameter
R3TR
"custom webdynpro application"
SERVICE TYPE and Service can be kept blank
after this try SU24 it will be available in SU24 list.
Thanks & regards

Are there any standard web dynpro ABAP or JAVA for material creation(mm41)?

Hi SDN,
I have got the requirement to provide Web Dynpro application for material creation (transaction code is MM41) and I would prefer to enhance standard Web Dynpro more than develop from scratch. Now I got only the Web dynpro ABAP component for create sales order called "LO_OIF_MAIN_COMP" and GUI HTML for purchasing order that come with business package Eh4.
Anyone who know please kindly help me.

>but I afraid that I'm not able to find out what is its component name from application
You could just lookup the WD Application in SE80 and then it will show you the component name. From SE80 choose Edit Object from the toolbar. Go to the Web Objects tab in the dialog. Type in the WD Application name and hit enter. You will then see the details of that application.

Web Dynpro ABAP and Case Management

Hi there!
How do i implement a case management subcomponent in web dynpro ABAP?
For classic GUI this is done by implementing the interface IF_SCMG_SUBCOMPONENT or by making CL_SCMG_SUBCOMPONENT_SP the superclass of your own class. But i don't know how this is going to work for wda.
Thanks a lot

Hi Karim,
Yes there is - try the function modules
HRWPC_OADP_DELETE_TGTOBJCACHE
HRWPC_OADP_DELETE_SRCHOBJCACHE
HRWPC_OADP_DELETE_NAVOBJCACHE
HRWPC_OADP_DELETE_DATAVWCACHE
Depending on what you want to refresh - you may not need to call all of them.
if you do this in the init of your app you can be sure to get the latest versions of the structure.
However, be aware that it can take some time for the OADP to read and build these structures - which is why they were cached in the first place! Depending on what you are trying to achieve, you may be better off (from a response time) building your own code.
Hope this helps,
Chris

Ess Time Sheet and Attendance Web Dynpro - ABAP or JAVA

We are determining the resources we will be needing for the HR - ESS Time Sheet and Attendance Module.
What is this module written in. ABAP Web Dynpro or Java Web Dynpro.
Many thanks,
Multiple replies welcome.
Ken

The ESSTimeSheet is now called Record Working Time & for now it is still in WebDynpro JAVA.. looking at how complex the whole application is, it will really take some beating to rewrite the same in WDA.

ABAP and Java in MCOD DB

Hi,
I don't know if I should post here or in the Netweaver forum:
SAP recommends if you want die use BI BAPA and BI Java to install two seperaterd systems.
In some presentations they suggest to use a MCOD database, so both instances have the same database.
In my understanding I would rather prefer two seperated databases than MCOD as it is not recommend for 'normal' systems.
Whats your experience with BI MCOD?
Thanks

Portal dynamic iView from Web Dynpro ABAP?

I wish to use a "Dynamic iView" from a Web Dynpro ABAP application, but it appears the API is only available in Web Dynpro Java. Can this feature be used from Web Dynpro ABAP, or can this be accomplished in another way?
Scenario: I have two iViews on a page, one Web Dynpro ABAP and another iView whose source I want to change dynamically based on something a user clicks in the Web Dynpro ABAP.
Dynamic iView:
http://help.sap.com/saphelp_nw70ehp1/helpdata/en/44/a72c155df77038e10000000a422035/frameset.htm

So you are suggesting the WDA fires an event to a new WDJ that we would need to create that would in turn use the Dynamic iView service mentioned in that help document?

Userid of a Portal-user in Web Dynpro ABAP

Dear colleagues,
we want to migrate our application from BSP to Web Dynpro ABAP and I'm looking for a procedure how I can get the userid of a Portal-user in Web Dynpro ABAP which is running inside an iView ?
In BSP I used iView application parameter user_id and in the BSP the event handler for data retrieval with:
userid = runtime->server->request->get_form_field( 'userid' ).
Found a lot of entries how to do it in Java but no one for WDA ?
Thanks in advance
Michael

Hi Michael,
Actualy it is not so trivial. You have some options:
1) In case user_id is parameter of iView you can read URL parameter like described here Webdynpro ABAP url-parameters
2) In case user_id is not iView parameter you can use usuall ABAP sy-uname system variable.
But pay attantion that it is not really EP user. Here we have 2 options: user mapping and SSO. In case of user mapping sy-uname will contain R/3 user which is mapped to EP user. In case of SSO sy-uname will contain same user name like in EP, because by using SSO user must ne the same on issuing and accepting systems.
Best regards, Maksim Rashchynski.

About configuration web dynpro abap

we have ecc5.0 and we cant use web dynpro there. can anyone please tell me how can we use web dynpro there? is it related any sap license related issue? please help me about giving me some knowledge about web dynpro installation and use.
From web every user should need one sap id or one common id can be use for login through web.

>please help me about giving me some knowledge about web dynpro installation and use.
There simply is not option to install or configure Web Dynpro ABAP on ECC 5.0 or earlier. Web Dynpro ABAP is part of the SAP_BASIS Software Component. The versions of ECC 5.0 and earlier simply didn't contain Web Dynpro ABAP. It was new in ECC 6.0.
If you want to create Web Dynpro applications, consider building a standalone ABAP or Java Application Server as a separate instance. You can then do Web Dynpro ABAP or Java development on this standalone instance and make RFC and Web Service calls to your older ECC 5.0 system.
