Best practice to develop internet app integrating with backend R/3 modules

While we wait to upgrade from R/3 4.6c, going forward we want to stop investing in ITS Flow Logic applications.
What is the best practice around using backend RFCs/BAPIs to expose SAP functionality as a web application that is accessible on the internet? One thought looks like using WAS 6.4 - utilizing JRA to call RFCs and using JSP/Servlet; another is to use Webdynpro based development. Will appreciate some architecture advice along side - especially if we also wanted internet surfers to set up user accounts. Thanks!

Hi Vito,
I do have the same situation as you and also some of the guys mentioned above as well. I have Portal only users and also users who uses the SAP GUI.
Thus, what I would advise, taking into consideration of audit as well, is to have the below scenerios:
1) Users who login to backend with SAP GUI on Citrix only
We have changed the system parameter: login/password_change_for_SSO=2
The password change dialog box appears and the password must be changed (input: old and new password). Also we have setup SNC (CyberSafe) so that in our SAP GUI, users can click on the system with SNC setup and login to backend without having to enter userID and password
2) Users who login to backend with SAP GUI on client (local)
Users will login with userID and password
3) Portal user with SSO and no login to backend vwith SAP GUI
Portal users will have their password deactivated.
Explaination to Audit for Portal users:
We have 90days password reset on Windows (AD). So our Portal users are respecting the audit request of having 90days password reset, but instead of having it in SAP, its in our Windows. Furthermore, SSO is setup as such that the coinnection for these Portal users to the backend is secure.
We are not able to set login/password_change_for_SSO=3 as we have sites which does not use Citrix. Thus, these sites will have local SAP GUI install.
Hope that can share some experience of mine to those who are also in my past situation.

Best practice when developing APEX apps and using a SVN repository

Hi experts,
I wanted to get your opinion on best practice regarding how to use SVN and APEX combined.
The idea is basically how to structure and how to save APEX apps the best way in a repository.
I am currently working with a custom SVN structure, not using the default TRUNC/TAGS one : every app has a folder , under every app folder i have PAge number folders, and for each page reports, regions and global objects separated.
This helps me because its more readable then saving the whole page export, its good for small changes and i have a clear overview of every bit and piece.
What is everybody else using or is there a best practice to follow here that i dont know?
Kind regards,
Alex

@tomaugerdotcom
Something like this might help: https://testflightapp.com/
Concevably, you could roll your own internal service if that particular one doesn't suit you. (I don't have any knowledge about how they are doing it, but it shouldn't be hard to figure out since Apple's constraining rules would only allow a few possibilities.)
USB app install and debugging isn't supported on iOS. You have to use wireless.
Another option specifically for multi-touch dev/testing, is to use an Android device.

Best practice for handling custom apps tracks with regards to EP upgrade?

Hi,
We've are currently in the progress of upgrading from EP 6 to EP 7.0, and in that context we need to "move" our tracks containg development of custom J2EE components.
What we've done so far is :
1.Create a new version 7.00 of each software component we have developed with correct EP 7 dependencies
2. Create a new version 7.00 of our product in the SLD: Bouvet_EP
3. Attached the new versions of the SCs to the new product version
4. Create a new track with the SC of version 7.00 along with relevant dependencies
My question now is how do we get the EP 6 component source code into the new track, so that we can change dependecies of the DCs and build it again for EP 7.0?
Should we somehow export the code from the old track, check in and transport ? (how do we then export the code from the track)
Regards
Dagfinn

Hi Dagfinn,
This is a really interesting thread. I have not encountered this scenario till now. However i can only guess.
1. Copy the latest sca files generated for all the SC's in your track from one of the subdirectories of JTrans and place those sca files in the inbox directory of target CMS. Check if these sca are available in the Check-in tab. I think this will not work because the SC verion you have defined in SLD for WAS 7.0 is different than the one in SLD for WAS 6.40.
2. Second and crude method may be you create a SC in the source SLD similar to ones created in target SLD. Create a track for these SC's in the source system. Then create a track connection between the newly created track and existing tracks. Forward all the sources to the target track. Then assemble this SC and copy the sca file and repeat the process above.
I dont know. Possibly this may click. Notes 877029 & 790922 also give some hints on migration of JDI server.
Please do keep this thread updated with your progress.

Best practices for apps integration with third party systems ?

Hi all
I would like to know if there is any document from oracle or from your own regarding best practices for apps integration with third party systems.
For example, in particular, let's say we need customization in a given module(ex:payables) need to provide data to a third party system, consider following:
outbound interface:
1)should third party system should be given with direct access to oracle database to access a particular payments data information table/view to look for data ?
2) should oracle create a file to third party system, so that it can read and do what it need to do?
inbound:
1) should third party should directly login and insert data into tables which holds response data?
2) again, should third party create file and oralce apps will pick up for further processing?
again, there could be lot of company specific scenarios like it has to be real time or not... etc...
How does companies make sure third party systems are not directly dipping into other systems (oracle apps/others), so that it will follow certain integration best practices.
how does enterprise architectute will play a role in this? can we apply SOA standards? should use request/reply using Tibco etc?
Many oracle apps implementations customizations are more or less directly interacting with third party systems by including code to login into respective third party systems and vice versa.
Let me your know if you have done differently and that would help oracle apps community.
thanks
rrb.

you want to send idoc to third party system (NONSAP).
what kind of system is it? can it handle http requests
or
can it handle webservice?
which version of R/3 you are using?
what is the mechanism the receiving system has, to receive data?

BEST PRACTICES: How to deploy apps with public and private content & data?

Can anyone recommend a guide, blog post, etc. on best practices for:
- designing & deploying apps that have publicly-accessible (http + https) content, and
- content and data for which users must be authenticated and authorized?
NOTE: In our environment users are authenticated via OID. We're using Apex 4.

Best practice to develop the news web part to retrieve news data across the farms

Hi,
We have developed the News Web part. The functionality it pulls the news from other SharePoint Farms and display it in the site. Currently we are using secure store service to to connect to different FARM to retrieve the news from that FARM.
The issue with this approach is that every time user hits the page it will always hit the Secure Store service.There are almost 80K users who will be using this web part. Moreover this web part connects to multiple sites for multiple news from different
division.What should be the best practice to develop such kind of web part without consuming the server resources and keep hitting the server till we get the new news.News does not change very often.
Regards
Rajaniesh

Hi,
According to your description, my understanding is that you want to know which is the best way to handle the large complication of SharePoint cross farm retrieving data.
If you are developing the custom web part to retrieve data from other farm, I suggest you can firstly create a custom timer job to get data hourly in the backend and restore the data in a list. Then you can create a web part to link to the list to display
the data.
For cross farm accessing data, I suggest you can create a custom web service to achieve it.
Also, you can use ajax to display the web part data asynchronously. It will improve the performance and reduce the server pressure.
Here are some detailed articles for your reference:
Create and Deploy Custom Timer Job Definition in SharePoint Programatically

Create asynchronous web parts for Sharepoint

What is the best practice for using the Calendar control with the Dispatcher?

It seems as if the Dispatcher is restricting access to the Query Builder (/bin/querybuilder.json) as a best practice regarding security. However, the Calendar relies on this endpoint to build the events for the calendar. On Author / Publish this works fine but once we place the Dispatcher in front, the Calendar no longer works. We've noticed the same behavior on the Geometrixx site.
What is the best practice for using the Calendar control with Dispatcher?
Thanks in advance.

Not sure what exactly you are asking but Muse handles the different orientations nicely without having to do anything.

FI/CO integration with PM, PS, MM modules

Hello,
Any body have information about ' FI/CO integration with PM, PS, MM modules
Could you please some explore above topic
Thanks,
Alex

HI Luciano,
It works as designed because of the following reasons:
1. The WBS ID in ERP system must be unique.
2. The phase-id in the cProject is NOT unique, you have e.g. same phase-id for two phases.
That is why the replication does not use the phase-id to create the WBS ID. The internal ID of phase is (default ID during creation of a phase) is used for replication
Though there is a Badi method let you change the the WBS ID, but I would not recommend you to do it because of above reasons.
Kind regards,

Best practice for developing with CRM 2013 (On Premises)

Hello all. I'm just starting to work with CRM, and I have some questions that hopefully will be simple for the seasoned developers. It's mostly just some best practice or general how-to questions for the group.
- When creating a new Visual Studio CRM Project I can connect to my CRM Instance and create new WebResources which deploy to the CRM instance just fine, but how can I pull all the existing items that are in the CRM Solution into the Visual Studio CRM project?
Or do I need to export the solution to a ZIP, expand it with SolutionPackager.exe, then copy these into my Visual Studio project to get it into sync?
- When multiple developers are working on changes is it best to keep everything in a Visual Studio project as I mentioned above, or is it better for everyone to have their own instance of CRM to code with so they can Export/Import solutions as needed then
these solutions be manually merged before moving into a common Test/QA environment?
- When modifying the submenu on a CRM form is it suggested to use Ribbon Workbench or is it better/easier to just export the solution, expand it with SolutionPackager.exe, modify ribbondiff and anything else required for the change, package it
back up, then reimport to CRM? I've heard from some that Ribbon Workbench has some limitations, but being green I wasn't sure what those limitations might be or if it'd be best to just manually make these changes. Or is thre any way to have a copy
of ribbondiff in Visual Studio and deploy this without having to repackage the Solution and Import in the ZIP?
I think that's it for now :) Thanks for any advise or suggestions. I really want to start learning the in's and out's of CRM and how all the pieces fit together. Also can someone direct me to some documentation or books that might give
more insight on developing for CRM 2013 or 2015 (moving to this soon)?
Thanks for your time.

Hi Sam
Also interested in best practice around this area - especially recommended development routes, unit testing, continuous integration etc - it would be great if you posted here if you find any good articles etc. At the moment we tend to just push changes
onto a live system as and when appropriate and I'd prefer to move away from that...
Thanks

Best practices for development / production environments

Our current scenario:
We have one production database server containing the APEX development install, plus all production data.
We have one development server that is cloned nightly (via RMAN duplicate) from production. It therefore also contains a full APEX development environment, and all our production data, albeit 1 day old.
Our desired scenario:
We want to convert the production database to a runtime only environment.
We want to be able to develop in the test environment, but since this is an RMAN duplicated database, every night the runtime APEX will overlay it, and the production versions of the apps will overlay. However, we still want to have up to date data against which to develop.
Questions: What is best practice for this sort of thing? We've considered a couple options:
1.) Find a way to clone the database (RMAN or something else), that will leave the existing APEX environment intact? If such is doable, we can modify our nightly refresh procedure to refresh the data, but not APEX.
2.) Move apex (in both prod and dev environments) to a separate database containing only APEX, and use DBLINKS to point to the data in both cases. The nightly refresh would only refresh the data and the APEX database would be unaffected. This would require rewriting all apps to use DBLINKS though, as well as requiring a change to the code when moving to production (i.e. modify the DBLINK to the production value)
3.) Require the developers to export their apps when done for the day, and reimport the following morning. This would leave the RMAN duplication process unchanged, and would add a manual step which the developers loath.
We basically have two mutually exclusive requirements - refresh the database nightly for the sake of fresh data, but don't refresh the database ever for the sake of the APEX environment.
Again, any suggestions on best practices would be helpful.
Thanks,
Bill Johnson

Bill,
To clarify, you do have the ability to export/import, happily, at the application level. The issue is that if you have an application that consist of more than a couple of pages, you will find yourself in a situation where changes to page 3 are tested and ready but, changes to pages 2, 5 and 6 are still in various stages of development. You will need to get the change for page 5 in to resolve a critical production issue. How do you do this without sending pages 2, 5 and 6 in their current state if you have to move the application all at once??? The issue is that you absolutely are going to need to version control at the page level, not at the application level.
Moreover, the only supported way of exporting items is via the GUI. While practically everyone doing serious APEX development has gone on to either PL/SQL or Utility hacks, Oracle still will not release a supported method for doing this. I have no idea why this would be...maybe one of the developers would care to comment on the matter. Obviously, if you want to automate, you will have to accept this caveat.
As to which version of the backend source control tool you use, the short answer is that it really doesn't matter. As far as the VC system is concerned, you APEX exports are simply files. Some versioning systems allow promotion of code through various SDLC stages. I am not sure about GIT in particular but, if it doesn't support this directly, you could always mimic the behavior with multiple repositories. Taht is, create a development repository into which you automatically update via exports every night. Whenever particular changes are promoted to production, you can at that time export form the development repository and into the production. You could, of course, create as many of these "stops" as necessary to mirror your shop's SDLC stages, e.g. dev, qa, intergation, staging, production etc.

Best Practice in maintaining multiple apps and user logins

Hi,
My company is just starting to use APEX, and none of us (the developers) have worked on this before either. It is greatly appreciated if we can get some help here.
We have developed quite a few applications in the same workspace. Now, we are going to setup UAT and PRD environments and also trying to understand what the best practice is to maintain multiple apps and user logins.
Many of you have already worked on APEX environment for sometime, can you please provide some input?
Should we create multiple apps(projects) for one department or should we create one app for one department?
Currently we have created multiple apps for one department, but, we are not sure if a user can login once and be able to access to all the authenticated apps.
Thank you,
LC

LC,
I am not sure how much of this applies to your situation - but I will share what I have done.
I built a single 700+ page application for my department - other areas create separate smaller applications.
The approach I chose is flexible enough to accomdate both.
I built a separate access control application(Control) in its own schema.
We use database authenication fo this app - an oracle account is required.
We prefer to use LDAP for authentication for the user applications.
For users that LDAP is not option - an encrypted password is stored - reset via email.
We use position based security - priviliges are based on job functions.
We have applications, appilcations have roles , roles have access to components(tabs,buttons,unmasked card numbers,etc.)
We have positions that are granted application roles - they inherit access to the role components.
Users have a name, a login, a position, and a site.
We have users on both the East Coast and the West Coast, we use the site in a sys_context
and views to emulate VPD. We also use the role components,sys_contexts and views to mask/unmask
card numbers without rewriting the dependent objects(querys,reports,views,etc.)
The position based security has worked well, when someone moves,
we change the position they are assigned to and they immediately have the privileges they need.
If you are interested I can rpovide more detail.

What is the best practice for developing web service?

Hi All,
I'm a newbee to web services...
I was wondering what would be the best approach in developing a web service,
using tools or programmatic approach?
If I use WebLogic Workshop, am I tied to a vendor?
Is it possible for me to develop web services using workshop and deploy in
another app server..?
I would appreciate if somebody could give me a pointer to start.
I have already referred BEA's docs.
I'm still confused on a good starting point on the best approach to develop
protable web services.
Thanks in advance for any inputs.

K K-
You have a very valid point on the simplify or complicate matters. If you are
going for clean and not-so-time-centric code, then there are several different
programs and packages out there you can choose from.
Since you are specialized in J2EE, than the Sun package may be what you are looking
for. BEA's classes simplify much of the work you will be doing, but you could
emulate their classes or extend yours above the functions provided in theirs.
It all boils down to how much work are you willing to do.
If you are asking for more detailed, coding 'Design Patterns' to utilize, I would
wait for a few more posts from other folks as my work often requires me to utilize
the tools provided.
Sincerely,
Eric Ballou

Eric,
Thanks for the response.
I was also looking at Sun's WSDP 1.1, which is more programmatic approach.
Some how, I feel being a J2EE developer, I should go on the direction
of the
programmatic approach.
Using the tools could simplify or complicate things. Also, the Workshop
samples import all weblogic specific packages.
My code looks so dirty with many vendor specific packages being imported.
Could you give me your suggestions for a clean and neat approach?
I would personally prefer to avoid the quick and dirty approach.
Thanks again.

The best approach in developing portable web services is knowing whatyou
are
planning on using them for as well as how much is willing to be spent,etc.
BEA's Workshop is portable to other frameworks, but the ease ofintegrating a
developed client or a developed server can very greatly. Even moreof an
issue
is migration from one framework to another. If you choose to developin
Workshop
and your company later deploys .Net solutions, some of your work mayhave
to be
redone unless the company is willing to keep portions of the 'old'system
around
until new versions of the service are available. However, Workshophas
several
ant tools available that would assist you in deploying to other appservers or
even a stand-alone application should you need cross framework abilities.
If you are just starting out in web services, http://www.webservices.org
is a
good place to start checking out vendors in the space.

Best practice for development using REST API - OData

Hi All, I am new to REST. I am a developer who works mostly in server-side code using Visual Studio. Now that Microsoft is advocating to write code using REST API instead of server-side code or client side object model, I am trying to use REST API.
I googled and most of the example shows to write a code and put it on Content Editor/Script Editor. How to organize code and deploy to the staging/production in this scenario? Is there any Best Practice or example around this?
Regards,
Khushi

If you are writing code in aspx or cs it does not mean that you need to deploy it in the SharePoint server, it could be any other application running from your remote server. What I mean it you can use C# & Rest API to connect to SharePoint server.
REST API in SharePoint 2013 provides the developers with a simple standardized method of retrieving information from SharePoint and it can be used from any technology that is capable of sending standard HTTP requests.
Refer to the following blog that provide your more details about comparison of the major features of these programming choices/
