Design Concern for XI Scenario!

Hi All,
Do you have any design solutions for following scenarios with respect to BPM,Adapaters and sync/async flow:
1. JSP -
> XI---->DB
2. JSP<--->SAPR/3<->XI<--->DB
3. DB-->XI->JSP
4. JSP<->XI<--->DB
Appreciated your time! Will get you reward!
Thanks,
PILearner.

I want to add more scenarios like
oracle -
xi--.NET--
R/3
and more hetrogeneous environment
Does any one know simple case studies or how to guides for hetrogenity in XI

Documentation on Designing tips - for different scenarios

Hi Gurus:
Is there any good doc's for 'Designing tips - for different scenarios' like using Line Item Dimensions, aggregates, copying ODS to ODS, cube modelling, cache....
The common scenarios we come across in real life..Of course I understand it varies from client to client
Would really appreciate any help..
Many thanks

Please suggest me a suitable design pattern for the scenario below

Hello,
I have around three to four methods in a class. And their invocation is mutually exclusive that only one of them can be called depending upon the scenario. usually to acheive this, what we do is, write if and else loops and depending upon the scenario, we call the method correspondingly. i thought of avoiding this if else loops and would like to know whether there is any possibility for achieving the same without if else loops? if yes how do we do this? is there any design pattern available?
Thanks, Aravinth

Hi,
In java we have something is called reflection; reflection is very powerful API. I would suggest the below to start with
public class Foo {
     public static final String METHOD_ONE="methodOne";
     public static final String METHOD_TWO="methodTwo";
     public void methodOne() {
          System.out.println("method one is being invoked..");
     public void methodTwo() {
          System.out.println("method two is being invoked..");
     public void methodInvoker(String scenario) throws Exception {
          Class clazz =this.getClass();
          Method method =clazz.getMethod(scenario, new Class[]{} );
          method.invoke(this, new Object[]{});
     public static void main(String args[] ) throws Exception {
          Foo foo = new Foo();
          foo.methodInvoker(Foo.METHOD_ONE);
          foo.methodInvoker(Foo.METHOD_TWO);
     }I hope this could help

How to Design ODS for a scenario

Hi All,
I need to load a flat file into an ODS. It has got separate fields for the ID and text of a characteristic(Key Field) and then I have few keyfigures/ DataFields and a navigational attribute in the ODS. The format looks like as follows:
Pnt_ID Pnt_Txt Matl_type Jan        Feb            Mar           APr            May              Jun             Jul
                                      Min Max    Min Max     Min Max    Min Max    Min Max    Min Max    Min Max
How do I design the ODS in such a secnario?
Please suggest a solution.
Regards,
Harika.

Hi,
       According to me in DSO use
2 characteristic in Key fields
Pnt_ID, Calmonth
2 keyfigure in data field
Max amount , Min Amount
and then load Print_txt in print_ID using text upoad.
Hope this will solve your issue.
any problem then ask me.

SAP PI conceptual best practice for synchronous scenarios

Hi,
 Apologies for the length of this post but I'm sure this is an area most of you have thought about in your journey with SAP PI.
 We have recently upgraded our SAP PI system from 7.0 to 7.1 and I'd like to document best practice guidelines for our internal development team to follow.
I'd be grateful for any feedback related to my thoughts below which may help to consolidate my knowledge to date.
 Prior to the upgrade we have implemented a number of synchronous and asynchronous scenarios using SAP PI as the hub at runtime using the Integration Directory configuration.
No interfaces to date are exposes directly from our backend systems using transaction SOAMANAGER.
 Our asynchronous scenarios operate through the SAP PI hub at runtime which builds in resilience and harnesses the benefits of the queue-based approach.
 My queries relate to the implementation of synchronous scenarios where there is no mapping or routing requirement. Perhaps it's best that I outline my experience/thoughts on the 3 options and summarise my queries/concerns that people may be able to advise upon afterwards.
 1) Use SAP PI Integration Directory. I appreciate going through SAP PI at runtime is not necessary and adds latency to the process but the monitoring capability in transaction SXMB_MONI provide full access for audit purposes and we have implemented alerting running hourly so all process errors are raised and we handle accordingly. In our SAP PI Production system we have a full record of sync messages recorded while these don't show in the backend system as we don't have propogation turned on. When we first looked at this, the reduction in speed seemed to be outweighed by the quality of the monitoring/alerting given none of the processes are particularly intensive and don't require instant responses. We have some inbound interfaces called by two sender systems so we have the overhead of maintaing the Integration Repository/Directory design/configuration twice for these systems but the nice thing is SXMB_MONI shows which system sent the message. Extra work but seemingly for improved visibility of the process. I'm not suggesting this is the correct long term approach but states where we are currently.
 2) Use the Advanced Adapter Engine. I've heard mixed reviews about this functionaslity, there areh obvious improvements in speed by avoiding the ABAP stack on the SAP PI server at runtime, but some people have complained about the lack of SXMB_MONI support. I don't know if this is still the case as we're at SAP PI 7.1 EHP1 but I plan to test and evaluate once Basis have set up the pre-requisite RFC etc.
 3) Use the backend system's SOAP runtime and SOAMANAGER. Using this option I can still model inbound interfaces in SAP PI but expose these using transaction SOAMANAGER in the backend ABAP system. [I would have tested out the direct P2P connection option but our backend systems are still at Netweaver 7.0 and this option is not supported until 7.1 so that's out for now.] The clear benefits of exposing the service directly from the backend system is obviously performance which in some of our planned processes would be desirable. My understanding is that the logging/tracing options in SOAMANAGER have to be switched on while you investigate so there is no automatic recording of interface detail for retrospective review.
 Queries:
 I have the feeling that there is no clear cut answer to which of the options you select from above but the decision should be based upon the requirements.
 I'm curious to understand SAPs intention with these options -
 - For synchronous scenarios is it assumed that the client should always handle errors therefore the lack of monitoring should be less of a concern and option 3 desirable when no mapping/routing is required?
 - Not only does option 3 offer the best performance, but the generated WSDL is ready once built for any further system to implement thereby offering the maximum benefit of SOA, therefore should we always use option 3 whenever possible?
 - Is it intended that the AAE runtime should be used when available but only for asynchronous scenarios or those requiring SAP PI functionality like mapping/routing otherwise customers should use option 3? I accept there are some areas of functionality not yet supported with the AAE so that would be another factor.
 Thanks for any advice, it is much appreciated.

Hi Aaron,
I was hoping for a better more concrete answer to my questions.
I've had discussion with a number of experienced SAP developers and read many articles.
There is no definitive paper that sets out the best approach here but I have gleaned the following key points:
- Make interfaces asynchronous whenever possible to reduce system dependencies and improve the user experience (e.g. by eliminating wait times when they are not essential, such as by sending them an email with confirmation details rather than waiting for the server to respond)
- It is the responsibility of the client to handle errors in synchronous scenarios hence monitoring lost through P-P services compared to the details information in transaction SXMB_MONI for PI services is not such a big issue. You can always turn on monitoring in SOAMANAGER to trace errors if need be.
- Choice of integration technique varies considerably by release level (for PI and Netweaver) so system landscape will be a significant factor. For example, we have some systems on Netweaver 7.0 and other on 7.1. As you need 7.1 for direction connection PI services we'd rather wait until all systems are at the higher level than have mixed usage in our landscape - it is already complex enough.
- We've not tried the AAE option in a Production scenarios yet but this is only really important for high volume interfaces, something that is not a concern at the moment. Obviously cumulative performance may be an issue in time so we plan to start looking at AAE soon.
Hope these comments may be useful.

How to design EDW for source systems from different Time-Zones

How to design EDW for source systems from different Time-Zones?
Suppose IT landscape has a global BW in New York, and source systems in americas, europe and asia, then how the time-zones effect on time related things like delta selections on date or timestamp etc.

As you said BW is global in NY, your source system must be global too. People from various locations can connect to same source system and thus timestamps for delta is always maintained as 1 single time. We have same scenario in our project. Our R/3 system is used by users in US and Europe. So we run deltas twice in day to make sure we got deltas from both locations.
If scenarios was such that all locations connect to separate R/3 system, then obviously you have multiple queues. That is unique delta queue for each source system so deltas will be pulled as per data in respective queues.

Assertion_Failed dump when accessing Design Time for Processes & Forms EP3

After exhausting SAP note searches and the SDN community forums, blogs & wiki searches, I decide to make my first SDN post:
After installing Enhancement Pack 3 to the base ECC 6.0, we got the Design Time for Processes & Forms node in the IMG under HR Administrative Services. I was able to get in to it the very first time without any issues; however once I selected one of the sample SAP processes, I received an "Assertion_Failed" dump in the section of code saying a referenced node must exist. In debugging, we did see a node that is referencing a node that does not exist, which is causing the dump. The dump occurs in CL_HRASR00_DT_OBJECT_BROWSER, Method ASSERT_OBJ_HIER_IS_CONSISTENT (line 71).
I now get this dump each time I try to execute the Design Time for Processes & Forms node in the IMG. Note: when accessing process the old way, there is no issue.
To me is seems like either EP3 was not installed completely, something went wrong in the activation of those business functions, or the copy of the sample forms from client 000 did not grab everything. In debugging, it appears that the missing reference node is related to some form scenario node. Also note that all the steps under Technical Settings were completed.
Has anyone seen this issue before?
Thanks for any help you can give. If I find the solution, I will post the answer here as well.

Hi Jeff,
I believe we had the same issue here.
There is an SAP Note (below) for this. Please let me know if this works.
Note 1075650 - New Design Time tool Corrections for the dump
Note Language: English Version: 1 Validity: Valid from 18.07.2007
Summary
Symptom
Dump on executing the transaction HRASR_DT which starts the new design time
tool of the HR Administrative services
More Terms
Design time tool HRASR_DT HRadmin
Cause and Prerequisites
Solution
The solution to the dump occuring would be resolved by applying the SP
Alternately the dump can be
resolved by performing the following steps manually :
1.Start SE16 transaction
2.Give the table name as T5ASRDTOBJHIER and press RETURN key
3.Execute the Selection screen by pressing on F8 Key
4.Select the following entries:
i. OBJECT TYPE = PROCESS and NODE TYPE = PROC_REF_FSCN_DIRECT
ii.OBJECT TYPE = PROCESS and NODE TYPE = PROC_REF_FSCN_DIRECT_START
5. Click on EDIT entries button on the header
6. Enter in the field REF_OBJECT_TYPE the value as FORM_SCENARIO
7. Click on the Next button on the header bar to navigate to the next entry
8. Repeat Step 6 for this entry also
9. Save the modification
Additionaly, perform the following steps as well:
1.Start SE16 transaction
2.Give the table name as T5ASRDTTOOLS and press RETURN key
3.Execute the Selection screen by pressing on F8 Key
4.Click on CREATE entry button on the header
5.Enter the following to create a new entry:
TOOL TYPE = FSCN_MSG_MAPPER
OPERATION = DISPEDIT
TOOL CLASSNAME = CL_HRASR00_DT_FST_MESSAGE_MAP
6. Enter the following to create a new entry:
TOOL TYPE = PROC_EXEC_FREQUENCY
OPERATION = DISPEDIT
TOOL CLASSNAME = CL_HRASR00_DT_PRT_EXEC_FREQ
7. Save the new entries
These adjustments should resolve the dumps hindering to start the new
design time tool

Entering custom backend service in Design Time for Processes and Forms

Hi all,
I am trying to create a form that have 3 fields:
1. pernr
2. ename
3. effective_date
I done all the necessary setup of BADI ,class, interface and form.
However I cannot seem to insert my custom backend service in the Design Time for Processes and Forms workbench (t-code:hrasr_dt).
Currently, I am just using SAP_PA for my backend service which is unable to load the ename into my form. The code in my custom class will not be triggered if I did not use my custom back end service in the Design Time for Processes and Forms.
Whenever I tried using my custom back end service, I will encounter the assertion_failed dump.
Anyone have any idea?
Edited by: Siong Chao on Dec 22, 2010 6:35 AM

Hi Siong Chao,
The filter name you have used in the BADI for your generic service requires to be defined in the Create / Edit Generic Service - Definition.( You can see this on selecting the Back-end services node under Form Scenario definition while using HRASR_DT transaction code)
Once you do that, you can import the fields defined in the Generic service BADI - using the same procedure used in standard SAP backend sevices.
Hope this clarifies. Please let me know if you have any further questions.
Best Regards

Design Concern Using PI

Can any one tell me: what way to call these kind of interfaces using XI:
1. Our client using code1 applications for address check.
we need to call these code1 applications through BAPI and send response back to BAPI.
Code1 applications are third party applications and using custom build database.
They are using some APIs(JAVA and C) for build this applications.
My question is : Will XI able to call these code1 applications using those APIs?
FYI :If I see the code1 application ,its like front end screen.
Flow like this:
BAPI(Request)->XI----->Code1
Code1(Response)XI----->BAPI
I am looking for design concerns about this kind of integrations?
Appreciated your time.
Thanks,

Hi,
can you try using other tools like Altova XMLSpy or SOAP UI Client to send request to SOLMAN?
If that works then it is some prob with the request from PI7.1 . If that does not work.. then you have to look at SOLMAN side what could be the problem.

SRM 7.0 for Standalone Scenario

Hi ,
We are planning to implement SRM 7.0 for Standalone Scenario. Is there any document or help to getting start this requirement? is it possible to create PO and other follow on documents in SRM and replicate them to legacy system in Standalone Scenario? you help will be great and thankful..
Jr.SRM

Hello,
You should start with downloading the configuration guide from [http://service.sap.com/instguides]. An installation guide for BASIS can be found here aswell.
I think that your requirement can definetly be covered, srm standalone <> legacy back-end. The method(s) (RFC/iDOC/XML cq PI) used depends on your landscape and how you design this.
You've got a big but nice challenge ahead of you. Good luck!

Creative Suite 3 Design P for how many computers?

Just bought Adove Creative Suite 3 Design Premium for over AUS $3000 and the shop told me that I could use on many computers...
How can I verify this?

Speaking as a lawyer, who I am not, the answer is no as the Suite license is a single, unbreakable unit. So using *any* application in the suite represents a use of the license; and therefore, non-simultaneous use is allowed, per the EULA.
Now, speaking as a non-lawyer, you have to think about what's reasonable. If you're actively working with Photoshop (say, creating a complex selection on a given image), can you really be working on Illustrator at the same time (the same person) on a second machine? Not very realistic, practical or effective. A different example could be that you're applying a complex filter on a large image (say 80+ MB) in Photoshop; which could take several minutes, in such case it's reasonable to think that you would step away from that machine to work on laying out a page in InDesign on the second machine.
The important thing is the essence of the EULA, not a word-for-word interpretation. Adobe wants to provide users with the convenience and flexibility of having a single license to be installed and used in up to two computers. The operating words here are convenience and flexibility. Having a single license used frequently and/or continuously on separated machines by different users moves away from the intent of the EULA really quickly (convenience and flexibility).
So the question is, with which one of the two scenarios/examples above do you identify your situation with? I think you can answer that yourself :-)

Design Pattern for Asynchronized Communication

I've got to implement a special protocol for network communication:
1. You'll have one connection, in this case, a TCP or UDP socket, all messages are exchanged via it.
2. You have multiple threads sending requests and receiving response concurrently using the same socket:
a. Each thread use a logic channel, which, from the thread's perspective, is an independant channel, the thread won't receive messages for other channels.
b. Each request/response is a packet that can be treated as atomic - you either send/receive it in one go or not at all. Each packet has the channel id, so you know which channel it belongs to.
c. For each thread, it sends request then waits for response, and then sends the next request and so on.
Hope the senario is clear.
So, some kind of notification pattern should be used here, I guess?
OK, check my pattern books, all of them are talking about callback stuff like listener, observer etc, however, they don't fit in this scenario, as each thread use their channel like a socket without knowing any details of underlying connections, their codes would be like:
sendRequest(req);
Response res = receiveResponse();The receiveResponse() needs to be a block call, so the only solution here is a wait()/notify() pair (this all I can come up with, you are welcome to suggest other pattern). So, a lot of synchronization would be going on, e.g., if the receiving thread (a dedicated thread that reads all messages from the underlying socket) notify the thread before it enter wait() status in receiveResponse() would result in serious bug.
I just wonder if there is a good pattern for this scenario? (I didn't read lots of design book, so may not be aware of such pattern). Any input are welcome.

Sounds like you've laid out your problem quite well.
You could use a fifo queue (producer-consumer queue) per thread - basically receiveResponse would check to see if there is anything in its (response) queue - if so, it is removed, if not, it waits. The socket thread receives a packet, finds the appropriate queue and pushes in the response - which wakes the receiver. This is thread safe, if done correctly - it is easy to do correctly.
Now that I think about it more, your queue can only store one element, given the request/response nature of the communication, so you don't even need to use a collection.
As for patterns, I think that Pattern Oriented Software Architecture Volume 2 (http://www.cs.wustl.edu/~schmidt/POSA/) may be of interest. And if threading and concurrency are of interest, checkout Concurrent Programming in Java, Doug Lea (http://www.amazon.com/exec/obidos/ASIN/0201310090/)

Flex design pattern for BlazeDS transfer objects

Dear Community,
I have a question regarding the nature of objects transferd from BlazeDS backend to the Flex client.
According to some adobe docs all the presentation logic should be in flex and BlazeDS should provide only services.
The question is what kind of transfer objects should be used? with what level of abstraction?
To make it more clear let's talk about a simple forum application like adobe forums.
I have created a Forum service, which returns a Forum transfer object, which has a List of Threads, with each thread having a List of Messages.
Flex gets the Forum transfer object and does all the presentaiton work.
This is a very nice seperatin of concerns architecture BUT there are two major performance issues:
- when the forum becomes bigger the transfer object will be huge
- the flex will use huge client resources to create the presentation of the forum transfer object.
So my question is what is your strategy/ design pattern for such a problem.
An obvious answer would be create services that include the presentation logic and use transfor objects like ThreadListPage which will include only the first 10 threads.
Thanks in advance

I think you are going to get a few varied types of answers to a general question like this, but I will comment on a few things. First, you should only be transmitting the data that you need to use or display to the user at the time. If this forum was implemented in Flex (I wish) you wouldn't transfer the text for all the threads. You might not transfer the thread text at all (just the subjects), you'd make calls back to the server to fetch that data when and if you need it.
Also, I think you are overestimating the resources required for the Flex "presentation layer". If you think about it, these workstations we have here are pretty idle most of the time when you're at a website. Nowadays there's plenty of processing power just sitting there waiting, so as long as your design isn't flawed the CPU or memory are rarely going to be a bottleneck with Flex.
The way I design, BlazeDS (or GraniteDS etc) should mostly just be "serving data". There is some flexibility available, for example I don't see a problem with putting certain types of business rules (such as a limit on the number of results that can be recieved in a search) within server side code, and validation rules on the Flex side. So there's not too many "industry standards" in Flex yet beyond maybe what's done in the various standard architectures, at least not that I'm aware of.
You might find it beneficial to look into some of the various frameworks/architectures available like Cairngorm, Mate, Swiz, and so on. Learning how they work (looking at examples) would probably answer some of your questions too.
