Newbie back end choice

When installing the trial version of Flash Builder 4 how does a newbie know what to choose as a back end?
Someone who just wants to "learn Flex in a week"?
Is there a FAQ somewhere, or do we need to post every question?
Thanks!

You do not need to install any backend technology to work through the Flex in a Week series. Data retreival in the series is performed against a live server that is already set up; the appropriate details are in the exercise directions.
If in the future you do want to learn how to create the code for the backend, you can choose any technology that can be accessed via HTTPService, WebService or RemoteObject components. You will learn about these components in Days 2 and 3 of Flex in a Week.
Also, when you install the Flash Builder trial version, consider installing the Premium, rather than Standard Edition so that you can follow the steps for using the Network Monitor.

JSP back-end interface to Remote server. Please help the newbie

Could someone comment on pros and cons of the JSP back-end interfaces to the remote server/programs using..
(1) Socket Interface between JSP and Remote Server. One socket for one JSP session. JSP to create and delete the socket when done.
(2) RMI between JSP and Remote program.
(3) Message Exchange using JMS between JSP and the Remote Server.
(4) Peer-to-peer JAXM message exchange. JSP/JAXM Client to Remote JAXM Server
(5) Anything else?
Thanks in advance..

(1) Socket Interface between JSP and Remote Server.
One socket for one JSP session. JSP to create and
delete the socket when done.JSPs are compiled to servlets, which use the HTTP protocol. The remote server should be the servlet/JSP engine.
(2) RMI between JSP and Remote program.As soon as you say "JSP", you're assuming HTTP request/response. If you want to talk to RMI objects, I think that's best done elsewhere than a JSP. They really should be for interface only. Have your JSP talk to a central, front controller servlet and have it invoke methods that deal with RMI objects or EJBs or POJOs on the back end. That stuff doesn't belong in JSPs, IMO.
(3) Message Exchange using JMS between JSP and the Remote Server.No.
(4) Peer-to-peer JAXM message exchange. JSP/JAXM
Client to Remote JAXM ServerNo. This is crazy. JSP = HTTP, which is client/server by definition.
(5) Anything else?All these might be fine options, but they don't belong in JSPs. Those should be for Web interface, a thin client. The details of how you process (e.g., RMI vs. EJB, synchronous vs. asynchronous, etc.) are best encapsulated somewhere else besides a JSP.
HTTP is a client/server, synchronous, request/response protocol, of course. As soon as you say JSP, these assumptions are built into your system. You can do asynchronous processing, but you still have to send back a response synchronously (e.g., "Your order is being processed. Please come back.")

URL vs. document attached in back end EBP 4.0 Classic/4.7 E

Based on documentation provided by SAP (Powerpoint) regarding new functionality available in SRM 4.0, we should have two choices regarding documents attached in shopping carts. One is the copy-to-DMS option well covered elsewhere, the second does NOT copy attachments to the back end but rather makes a URL available in R/3.
We are attempting this URL approach:
Instantiated BAdI BBP_CREATE_REQ_BACK (note to the reader, there is a different BAdI for SRM 5.0)
== Start Code Change ===
CV_ATTACH_USE_URL ='X'.
CLEAR CV_ATTACH_TRANSFER_ACTIVE. "i.e. we are not transferring documents
== End Code change ==
Configured the badi, attached the method, configured SICF, etc.
We have NOT configured DMS in R/3.
Created new requisition/shopping cart
Adopt the requisition
Select attachments Icon in SAPGUI, no documents found.
Has anyone tried this URL method? Did you get it to work? Is DMS still used? We are guessing a simple text file may be transferred with the attachment URL's, which would require DMS.
Any suggestions on debugging the situation?

HI Daemeon
The attachment transfer from shopping cart is very simple just follow the steps below
Following are the steps -
In SRM - Activate BADI - ZBBP_CREATE_REQ_BACK
method - FILL_REQ_INTERFACE
parameter - cv_attach_transfer_active = 'X' set active.
In R3 in DC10 create a new document type for SRM
IN DC30 check all extensions are maintained properly.
Logout and login and all the attachment gets transffered fully.
check one process with attachment It will work.

How to know which radiobutton is selected in case of dynamic UI generation and how to pass it to back end?

This is how I have written for dynamically generating radiobuttons. I have some categories on left view, by selecting which, i will get corresponding questions and it generates 5 options, and user selects one and I need to pass it to back end. I am using IModifiableSimpleValueSet for filling the radiobuttons.
ISimpleTypeModifiable myType = wdThis.wdGetAPI().getContext().getModifiableTypeOf("Ans.option");
IModifiableSimpleValueSet values = myType.getSVServices().getModifiableSimpleValueSet();
values.put(d,wdContext.nodeAns().getElementAt(d).getAttributeValue("option").toString());
Kindly help, if I am missing something.
IWDRadioButtonGroupByKey radioKey = (IWDRadioButtonGroupByKey)view.createElement(IWDRadioButtonGroupByKey.class, "ansRadio"+radio_count++);
IWDMatrixHeadData matrixHead_radio = (IWDMatrixHeadData)radioKey.createLayoutData(IWDMatrixHeadData.class);
IWDAction radioAction = wdThis.wdCreateAction(IPrivateRightView.WDActionEventHandler.SELECT_ANS, radioKey.getId());
wdComponentAPI.getMessageManager().reportSuccess("radio id"+radio_count);
radioKey.bindSelectedKey("Ans.option");
radioKey.mappingOfOnSelect().setString("optionID", radioKey.getSelectedKey());
wdContext.currentContextElement().setSel_ans(wdContext.currentAnsElement().getOption());
radioKey.setColCount(1);
questContainer.addChild(radioKey);

Hi Jun,
I have to prepare a questionnaire. Some set of questions will be there in backend having 5 options. Based on category I have to fetch questions and its corresponding answers. Ans is the node which I am filling with choices, based on questions.

Changes to the Back-end....Bringing it on to the Front-end

Hello All,
I would like to know the means of reflecting the changes made to the back-end tables on to the front end. Say we've a departments table and an ADF UIX page displaying the data from it in the front-end... we make certain modifications to the back-end table.. Now how do I bring it on to the already existing front-end UIX page. Could anyone give me a solution for this. Thanks in advance.
Regards,
Arun.V

Hi,
If you have navigated to the employees from selected department (ie, all the employees on the page are from the same department) then you can just drag the department name onto the page to create the bindings and display the department name.
If you are going direct to empoyees in a read only table an easy solution is to create a business component based on a database view that joins the two tables and presents the employee details and the department name.
create or replace view emp_dept as
select e.emp_id,
       e.emp_name,
       d.dept_id,
       d.dept_name
from emp e,
     dept d
where e.dept_id = d.dept_id; If you want to edit an employee then create a view link to a ViewObject which represents just employees using the employee id. On the single record edit page use a message choice to translate the department id into the department name.

Inconsistency between Bex and Back end

Hello, I have a query about bex issue. I have few fields in my DSO/Cube which has data showing correctly in the back end but in Bex it shows partial of those values. like if i have something like this:
ZField
000000000000000000008
It shows correct in DSO table but in Bex it only shows the zeros. do you know why and how to get this to show the whole field value?
Thanks.
By the way this is a characteristic and not keyfigure.

Hi Vekant,
If you have not did any speecific thing at query level then value should be shown correctly.
Please try this once and check.
Create new test query on your data target drag and droup your charecteristic.please execute your test query and see if you are able to see the correct value.
try this.

Front end and back end questions

Hi,
If I want to develop a web base SOA application by using Jcaps, I have several question want to ask.
1.) In the front end, if i create the page by using eVision to create the page
flow and the page layout, how can I match the fields of the page (such
as the username, email, tel no... with the back end web services?
2.) Does the flow of the front end web pages are control by the page flow in
eVision? When will the eVision supported AJAX or JSF?
3.) What is the use of the eInsight Business process manager, does it
control all the back end flow, such as the flow of each web services?
Does Jcaps has the Bpel engine to control the flow of web services?
4.) I know that in JBoss, there is a jBPM server to control the flow of the front
end pages, does JCAPS has this kind of server?
5.) If i want to connect to the Database? I know that there is a eTL to extract
the data from the database, it is true? Or do u recommend to connect the
database directly through the web services by using JDBC or other
framework as well?
6.) If I have an existing application that is developed by .Net (With no web
services). How can i integrate with other systems? What can I do in order
to reuse the system? Or what Jcaps can do in this manner?
Thanks for you reply! ^ ^

Generally, back-end would consist of the taks associated with configuration of data targets (ODS, Cubes), working with extractors, mapping data to the data targets, writing transfer/start rtn/update rules, and creating Infopkgs/ Process Chains.
Front-end deals with the use of the BW - writing queries, workbooks, web (although I think some of the infrastructure aspects of web reporting. e.g. javascript/templates might really could be considered backend). Think of Front-end as all of the client/customer/user facing components.

Refresh table and display the records after insertion of data from back end

Hi Experts,
JDEV 11.1.2.1
I have a useacase which needs data to be inserted from oracle back end procedure and displayed in a ADF Table Component, when a button is pressed.
is this possible?..if yes , how?
Is view object will automatically refreshed and fetches newly created(from back end) rows?
thankz in advance
PMS

Hi user707,
thankz for ur reply....
i think after executing a procedure you want to call commit operation. better you can perform this.getDbtransaction().commit In Application Module;yes i want to commit transaction after executing back end procedure using preparedStatement.Procedure is for inserting data into same table , which used for creating VO and Read only ADF Table.Procedure is executed fine, but newly created records are not getting into ADF table.Once i did commit opeartion inside back end procedure, whole records are getting into ADF Table.
Is there any way to get whole records without doing Commit operation inside Back end procedure?

Deletion of filter components from Bex Report in BI 7.0 via back end.

Hi,
I want to delete 2 filter field components from the BI 7.0 report via back end. Im using the Tcode RSZDELETE and giving the variable element UID, Inforprovide name, query tech name. But when i excute it says empty selection.
Other than this is there any way to delete query components at back end???
Regards,
Nisha

Thanks for the reply!
This is to delete the variable created??
My requirement is query specific , the restriction on the IO , ie the variable to be removed via back end.. that means deletion from that report..
hope my statement is clear enough to give me some light .
Thanks

Client Copy back-end system

Hi Guys,
We have made a client copy of the back-end system of SRM (SRM 5.0). Only the back-end and not SRM has been copied.
After replication all the master- and customizing data again to SRM from the 'new' back-end I have found an issue with updating the suppliers.
It seems that I can not remove old business partners from SRM with BUPA_TEST_DELETE if these are used already in SC's. However the new copy of the back-end system has completely different suppliers we need to use in SRM. This causes for an inconsistency with the supplier numbers, as we want to keep the R/3 numbers in SRM.
Does anyone has a good idea how to proceed? That is, how can I remove the business partners (suppliers) in SRM which were used before the client copy of R/3, so that I will be able to completely get all the relevant 'new' vendors from the R/3 system after the client copy.
When I execute BUPA_TEST_DELETE it will end up in error saying the suppliers can not be removed. Do I need to archive all the old documents (SC & PO) before I can remove all vendors in SRM, or is there a way to force the removal of all the business partners from before the back-end client copy?
Thx.
Skander

Hi,
I already figured out how to solve the issue.
For anyone who wants to know how to:
-First clear the vendor groups in the vendor hierarchy; do not renove the root node
-Then run BBPGETVD which will get you the new vendors from the back-end; for me only role LF for suppliers.
-Then run BBPUPDVD which will update all the fields for the old business partner numbers in SRM which were used in documents, and replicated from the old back-end system.
In my case I had to play a litlebit with the setting 'only creditors', to update BP numbers which were not suppliers in the new back-end.
After performing these steps everything should be fine.
So it's perfectly possible to make a client copy of only the back-end system without copying SRM (in the classic scenario that is).
Rgds,
Skander

Dynamically switch back-end servers...

Hi, ours is a middleware layer that connect directly to back-end systems. There
is a new layer coming in between our layer and one of our back end system. I want
to device a system that will skipp this layer and directly start communicating
to the back-end programatically. That is at run time without getting the servers
down and changing the configuration to send to the back end system straight.
One way of doing this is shared memory where it read a value and depending on
this value set will route requests thru this new layer or directly send it to
backend. My only concern is, under high load conditions multiple processes of
the same server instance will keep on accessing this value. May be there are lot
other ways of doing this programmatically.
I want to know if there is any other way of doing this in the tuxedo environment?
thanks,
Sachin.Rane

Hi Sachin,
You don't give details of your configuration (i.e. SSSQ or MSSQ) but perhaps the
following will work:
Include an additional service that is unique to your server (e.g. "ADMIN<servername>")
and when you want to switch make a call to that service (using ud32, or write
your own client). In this way the server will only act on receiving the message,
and will not have to keep checking shared memory.
Let us know if this solves your problem - if not please describe the situation
in more detail (for example, is the additional layer Tuxedo-based? etc.).

What is BW Front-end and Whats BW Back-end? Technica ? Functional?

Hi Gurus,
Can some one throw light on the diff between a BW Front-end and BW BAck-end? How will u diff the responsibilities of a Functional BW Consultant and Technical BW Consultant?
thanks
kishore karnati

Hi,
BW Front end is the one that deals with reporting. Eg: BEx
BW back end is the one that deals with the components that stores data which is used for the reporting purpose.
Eg: R3
Functional consultant comes into picture when there is a need to understand the functional aspects of a requirement, say for example, you have a requirement to use Sales Order in your BW application, as a pure BW person, you wont know what a Sales Order is about. A functional consultant has the ability here to map the sales order requirement in the BW application. This means that, he knows what field and what table this sales order relates to. This way, a functional consultant maps the user requirements to the technical detail in the system.
A pure BW consultant is one who knows how to setup data extraction from source system , how to build various components in a BW system, how to schedule a load, how to troubleshoot in case of any issues in the BW application.
Hope this helps..
Assign points if this helps...
Thanks,
Raj

Vendor Replication and Different Back-end Systems

Hello,
Currently, we have vendor replication were the vendor number from the back-end is used in SRM-EBP. Now, we want add another back-end but there are vendor number conflicts. Is there a way to configure it so that the new back-end replicaition generates new numbers in SRM-EBP?
Honestly, there should be a cleansing and alignment of vendor numbers between the two back-end systems. However, that is big task that the organization doea not want to take on at this time.
Has anyone encounter this issue and how did you resolve it?
Regards, Dean.
Edited by: Dean Hinson on Feb 3, 2010 3:26 PM

Hi,
You can find option "If R/3 number assignment is not possible: Internal number assignment" in the bottom of BBPGETDV transaction screen.

About back-end adapter and IDoc

Hi everybody!
I was watching in the FAQ of Mobile 7.1 about the possibility to use IDOC as a mechanism to push data to DOE, but this document only says: "IDocs are supported only for back-end-triggered scenarios" and provides a link to configure ALE between the backend and DOE, but the link doesn't work. (Somebody has this information on a link that works?)
I'm trying to find any information, blog, article, how-to guide, however I cant found anything. Anybody has documentation about how to configurate and implement a backend-adapter to push data from the backend through IDOC? Any information will be welcome.
Thanks in advance.
Best regards,
Simon.

Hi San,
You will have to look after this in Tansaction SE80. Open the BSP application cProjects, and find the appropriate view. (The naming convetion will help a little). Open the view tab: layout >> e.G. progAssignedPha.bsp Here you will find what BSP elements it consists of. You will find the
<htmlb:tableView and <htmlb:inputField ... elements.
Here you will find the information you are looking for.
As easy as in SAPGui you can not find out this information.
Regards.
