Best practice identifying ERT modules with SAP / IS-Utilities

Hi everybody,
I'm looking for the best practice identifying ERT modules with SAP / IS-Utilities (electricity).
Here's the physical device set up :
The ERT modules are internal to the electricity meter. They're integrated into a multi purpose electronic circuit. So they can't be remove physically as a separate device.
The ERT modules are used to transmit data from the meter to a radio frequency receiver (handheld or drive-by). The main data that is transmitted is the consumption reading. So the receiver stores the ERT module number and the reading value.
They may be one or more ERT modules in a single meter, and each ERT module transmit his own specific consumption reading (energy reading, demand reading, etc...).
Each ERT module has is own manufacturer number.
My issue is :
To find a way to identify in IS-U the ERT module within the meter's register group (or somewhere else???) in order to relate each register to his ERT module number.
The purpose of all this is to create reading orders with the ERT module number following for each register.
This way we can match, using a unique key, each reading order and his corresponding reading value uploaded from the radio frequency receiver (handheld or drive-by).
Thanks for your help and ideas on best practice.

Hi,
1) The system (application) environment of BI (what is integrated in it - e. g. within the portal, there is a storage for unstructured information like documents or virtual rooms for collaboration between departments - and what does it make)
Document management from RSA1 transaction of BI helps to attach any unstructured documents at specific level in BI.
2) How does development in BI works (development environment, coding, debugging, building, deployment and test) and what is used stronger (ABAP or ABAP OO)? Here, I don't mean how to write ABAP or ABAP OO programs, only the infrastructure from development to transport to a target system
BI has got a separate tool and GUI to perform all the Extract, Transform and load related activities. ABAP is part of BI but you don't need much extensive ABAP learning. Basic ABAP is sufficient to write routines and extractors.
3) How is a BI system to configure as default after installation?
May be a BASIS person can help you out here about the configuration but this is not the job of BI person.
4) Good guides (e/books) to learn ABAP and ABAP OO (as far as possible oriented on the practive)
You can search for SAM Series learn ABAP in 24 days book. This book is sufficient to learn the ABAP required for working in BI.
But except ABAP you will have to completly learn the BI system to work efficiently.

Durgesh.

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 practice when using Tangosol with an app server

Hi,
I'm wondering what is the best practice when using Tangosol with an app server (Websphere 6.1 in this case). I've been able to set it up using the resource adapter, tried using distributed transactions and it appears to work as expected - I've also been able to see cache data from another app server instance.
However, it appears that cache data vanishes after a while. I've not yet been able to put my finger on when, but garbage collection is a possibility I've come to suspect.
Data in the cache survives the removal of the EJB, but somewhere later down the line it appear to vanish. I'm not aware of any expiry settings for the cache that would explain this (to the best of my understanding the default is "no expiry"), so GC came to mind. Would this be the explanation?
If that would be the explanation, what would be a better way to keep the cache from being subject to GC - to have a "startup class" in the app server that holds on to the cache object, or would there be other ways? Currently the EJB calls getCacheAdapter, so I guess Bad Things may happen when the EJB is removed...
Best regards,

Hi Gene,
I found the configuration file embedded in coherence.jar. Am I supposed to replace it and re-package coherence.jar?
If I put it elsewhere (in the "classpath") - is there a way I can be sure that it has been found by Coherence (like a message in the standard output stream)? My experience with Websphere is that "classpath" is a rather ...vague concept, we use the J2CA adapter which most probably has a different class loader than the EAR that contains the EJB, and I would rather avoid to do a lot of trial/error corrections to a file just to find that it's not actually been used.
Anyway, at this stage my tests are still focused on distributed transactions/2PC/commit/rollback/recovery, and we're nowhere near 10,000 objects. As a matter of fact, we haven't had more than 1024 objects in these app servers. In the typical scenario where I've seen objects "fade away", there has been only one or two objects in the test data. And they both disappear...
Still confused,
/Per

Best practice for sharing data with model window

Hi team,
what would the best practice for sharing data with a modal
window be ? I use a modal window to display record details from a
record list, but i am not quite sure how to access the data from
the components in the main application in the modal window.
Any hints would be welcome
Best
Frank

Pass a reference to the parent into the modal popup. Then you
can reference anything in the parent scope.
I haven't done this i 2.0 yet so I can't give you code. I'll
post if I do.
Oh, also, you can reference the parent using parentDocument.
So in the popup you could do:
parentDocument.myPublicVariable = "whatever";

What's the best way to connect Cognos with SAP 4.6c on iseries V5R4

We have SAP 4.6c on iseries V5r4.
What's the best way to connect Cognos with SAP so that data could be extracted from SAP and create reports with Cognos.
Thanks
Joe

DB2 Connect version 8.2 is no longer supported by IBM (support ended April 30, 2009, see http://www.ibm.com/software/data/support/lifecycle/). As far as I know, DB2 Connect is communicating through DRDA, which is a platform-independent protocol supported by all DB2 platforms, so any DB2 Connect client should be able to talk to any DB2 database. However, there may be limitations on the supported release combinations.
Kind regards,

Basic Strategy / Best Practices for System Monitoring with Solution Manager

I am very new to SAP and the Basis group at my company. I will be working on a project to identify the best practices of System and Service level monitoring using Solution Manager. I have read a good amount about SAP Solution Manager and the concept of monitoring but need to begin mapping out a monitoring strategy.
We currently utilize the RZ20 transaction and basic CCMS monitors such as watching for update errors, availability, short dumps, etc.. What else should be monitored in order to proactively find possible issues. Are there any best practices you all have found when implimenting Monitoring for new solutions added to the SAP landscape.... what are common things we would want to monitor over say ERP, CRM, SRM, etc?
Thanks in advance for any comments or suggestions!

Hi Mike,
Did you try the following link ?
If not, it may be useful to some extent:
http://service.sap.com/bestpractices
---> Cross-Industry Packages ---> Best Practices for Solution Management
You have quite a few documents there - those on BPM may also cover Solution Monitoring aspects.
Best regards,

Best practices of BO/BW SSO SAP Authentication transports

Hi Friends,
We are going to integrate BW system with BO (SAP authentication). All the queries are built through BICS connections. And we have various reporting tools to implement SSO SAP authentication (Webi,Crystal,Dashboard.Design studio…etc)
As per the process there are certain activities which has to be performed at BW level
e.g -- BW Roles creation (PFCG---Crystal role enablement) and assigning to BO users
Once it is created in BW , we have to do integration at BO level( in CMC application) by selecting authentication and roles import followed by ……Groups..Users…folder and access level...
My question here is
Transports of BW objects for BO SSO (SAP) authentication (such as roles created for Users, Keystore certificate, uploads). Will these objects be transported by BW team or they will be separately downloading or uploading the certificate in different systems (like QAS ...PROD….)
And at BO level, once I integrate BO SSO, Do I need to do manual integration in QAS and Production system as well or it can be transported with promotion management of BO tool
Will these SSO(SAP) authentication can be applied to all tools in BI Launchpad such as (Design studio,Webi,Web application,Crystal….etc) as all users are required to have SSO to all BO tool
Regarding LUMIRA tool , Can we do SSO authentication
Please share your thoughts and experience.
I t would be great if I get BO administration best practices document for BW BO SSO and Users and Group management in CMC for implementing
Thanks in advance

Hi ,
Please find my answers below:
1. The roles will be created in BW and should automatically appear in BO CMC Authentication SAP roles, if there is a connectivity setup between BO and BW irrespective of the SSO.The roles are transported by the BW security team.
2. Every environement will have a unique connection to the corresponding SAP BW environment.For example SAP BW DEV will be mapped to BO DEV, SAP BW PROD will be mapped to BO PROD.So these settings cannot be migrated through Promotion Management.
3.This authentication can be applied to all tools , the SSO does not depend on the tool ,it depends on the integration between two systems which in this case are BO and SAP BW
As mentioned earlier, after integration all tools can have SSO
You can refer to a lot of help documents on this site which will help you to setup the integration between SAP BW AND SAP BO.
Kind Regards,
Priyanka

Best practice for application module for scalability

if i compare application module with forms 6i runtime session.(correct me if i wrong)
In forms 6i, we create for single form for purchase entry. in which we select table like po , po_item, item_master, customer master
also single form for sales entry. in which we select table like sales , sales_item, item_master, customer master, po , po_item
So my question is. in jdeveloper , we planning to make separate jsp page and applicaiton module for purchase entry,
separare jsp page and application module for sales.
is it ok.
or
what is the best practice in this senario.?? ( or in scalability senario)
if i made one single application module for whole application (let say 300 entity's(tables)) will performance of my app server degrade.

Best practice for function module development

When designing a function module, what is the best practice. Should we develop it so that most of the extraction is done within the function module, or should we develop it such that prior to calling the function module the extraction should be done in the main calling program and the function module would have a huge interface of many importing parameters?
For e.g. lets say for some business logic I need MATNR MTART MEINS BSTME and so on. Now by knowing the matnr I can get all the other fields. Should I create a function module with just matnr as importing parameter and do the Select on MARA in the FM or should I create the function module with all the fields as required importing parameters. What would be a best practise in such a scenario.
Thank you.

Now we are getting into the ecapsulation part of function groups. Did you know that when you run your program, and it executes a FM, that ALL function modules in the function group are loaded into memory? And that global data inside the function group can be shared across functino module calls? This is how you would relieve your concern. Lets say that all of your function modules belong to the same group, And all of them need to use a record from MARA, and you don't want to do a SELECT in all of these functions. Basically, you just create a global structure variable in the TOP include of the function group. In the first FM, you simply do the select and put that data into the global variable, then during the next FM call(the FM must be in the same group) you can get the data from the global variable directly without having to go to the database.

Modules with SAP FI

I have done my certification in SAP FI, a few months ago. But everywhere I go for an interview, I saw that they require FICO consultant. I know, CO was part of this complete module. But now, its separate. So, I wanted to ask whether I have to do CO too in near future? What about any other Module then after, to enhance my knowledge and value as a functional consultant? Only tell the best combinations with SAP FI module, please. I have heard about some BPC module. Wanna hear your opinion..

Hi Rahul,
Previously there was a consolidated course for FI and CO and that is the reason why generally the term FI-CO consultant is used.
Bust as you said these days both the modules are separated namely FI & CO but;
The general knowledge which required to activate Co module and creating Cost center and Profit Center, Creating internal order creating hierarchy etc. are covered in our TFIN 50 & TFIN 52 course.
In my opinion at this point of time what you need is an opportunity and that is not assured even if you qualify in CO module.
If you surf through Career center, it is flooded with Job / Opportunity related questions.
It is like "What comes first, Chicken or Egg ?" there is no answer to this question.
Same way in the field of SAP there is no answer to the question "what comes first Experience / qualification or Job ?"
Detailed configuration and integration of Co module is just a matter of one project if you are thorough with FI module.
There are many books available of CO module in market or online.
Please read this blog which might help you,
ERP Consultancy (SAP Certification) – Transformation from Introduction Phase to Mature Phase (Part – 2)
I hope I could answer your question "whether I have to do CO too in near future?"
Wish you all the best to break this vicious circle.

Best practice versioning XI szenario with java proxies

Our XI scenario includes services with java proxies.
By changing the message structure, java proxies have to be changed, too. But not all connected application can migrate to new message structure at the same time.
I need a solution to run different versions of the same scenario at same time. This is also a requirement to my java proxy service. Thus I need to run the java proxy service under different versions.
To maintain minor and major changes, what would be the best practice for versioning in XI scenarios and for java proxies?
Is there a better solution than use different namespaces inside the XI scenarios (e.g. add the version number) and use different EJB-names for the proxy services (e.g. include the version number in the name)?
Thanx,
Michael

Hi Michael,
I don't have a best practice for you, but...
In general, you tend to run into trouble when making incompatible changes to message structures. Since the Software Component Version is not used as part of the message key (only interface and namespace is used), you can't use this versioning mechanism to help you. Thus you are forced to create a new interface instead of a new version of the same interface. If you can think up a new name (that won't just cause confusion), fine. Otherwise you are forced to include an version identifier in either the interface name or the namespace. The latter is used in some public XML schema definitions e.g. xCBL. In other words: versioning via namespaces. Not exactly elegant, but perhaps your best bet.
Best regards,
Thorsten

Best Practice AV set up on SAP Servers

Hi,
Has anyone come across or aware of any best practice guidelines for AV setup on SAP servers, for example, which files/drives should you exclude and configuration tuning/reg-edits required. We have McAfee as our standard AV and we do use the HIPS component.
Thanks,
Martin

My best advise is:
Don't run AV on a database server but rather reconfigure the local/a firewall so that only those ports are open which are necessary to run the SAP application.
Excluding files may help a bit but neverless, as soon as the AV scanner is installed it will hook up to the filesystem layer and slowing down (maybe not significantly) I/O. I've seen weird side effects in upgrades and patch installations due to an enabled scanner although the database files and executables were excluded from scanning.
If you're urged to run Windows servers then I would put them in a separate network segment with a firewall in front and enable only the necessary SAP ports (and printing ports). This has a number of advantages:
- nasty RPC bugs can't be exploited because RPC to the SAP system should be disabled
- there's no need to reboot the Windows machines on every "Microsoft patch day"
A virus scanner adds, especially for production database systems, an indeterministic risc to the business.

Best practice for placing module

Hello
I have an enterprise application project, with :
1) EJB Module
2) Web Module .
I want to add the hibernate jars+classes+data+servlets+utils etc...
Should i create a new Web module for hibernate or should i add it to the existing EJB module which is my business logic ?
What is the best practice for that?
Thanks !

Thanks for the reply, Jiri.
I believe that the answer is 'yes' to both of your questions above. I do have a question about the formatting of the meta tag itself, as my main question is how do I extract the needed information from a particular CDF so that it is displayed in the <head> section located in the page template.
I have a Region Definition for the content section of my page with a 'Title' field, which a contributor can fill in, save, and create a Contributor Data File with their own specified title. Let's also say that my page template, which formats the entire page, looks like this (rough):
<html>
<head>
<title>Web page</title>
</head>
<body>



</body>
</html>
What would my <meta> tag look like for the following:
<meta property="og:title" content="Title of the content section"/>
Let's name our templates/definitions:
Page Template: PT_META
Region Template: RT_META
Region Definition: RD_META
Contributor Data File: CDF_META
In other words, how do I extract the information included in the Contributor Data File (as well as its metadata) for use in the Page Template? Is there some sort of Idoc Script call that can be used?
Thank you so much,
Josh

Teststand best practices architecture for communicating with TCP instruments

Hi,
I am using Teststand 2014 and LabVIEW 2013 SP1 as the module adapter.
My Teststand sequence file includes communication with 3-5 different instruments via TCP/IP.
Such as Spectrum analyzer, generator and other RF measurement devices.
There are many steps located in subsequences that implement code to communicated with these devices whether to fetch , query or write.
What is the best architecture to implement this program ?
As I can see it there are many possibilities, such as :
1. Launching a subsequence as a new thread in the Sequence Setup. This subsequence calls a VI that dynamically register for events/queue that can be launched from any step. (in this case there is a VI running in the background that can perform Write/Read/Qurey to the instrument and he is triggered from any step using an event or dequeue element)
This option can be duplicated for any instrument or only once for all of the instrument with prioritizing the event queue.
2. Creating a communication reference in the Setup of the Main Sequence. And passing it to any step that need it. (there is also the question how to pass this reference… in Teststand globals or in LabVIEW queue).
another 2 small questions that I encountered -
Is using LabVIEW queues and notifiers in TS steps and obtaining their reference (in the LabVIEW code) by name is considered best practices ?
If I would like to run only one VI in a new thread, should I use a new subsequnce and set it as a new thread or use the Run VI Asynchronously ? what are the differences ?

I use Action Engines to hold my VISA Sessions and just write my LabVIEW VIs to use those to send commands and read data. Any returned data can be analyzed in the VI or passed on to TestStand as a step result. You just need a sequence to run at start up to initialize your Action Engines and another one to close them.
There are only two ways to tell somebody thanks: Kudos and Marked Solutions

Best Practices for sharing media with iMovie and FCPX

So I've a large iMovie Events directory, and would like to use that media with both iMovie and FCPX projects.
I'd rather not duplicate the media, so would prefer to import as references into FCPX.
The dilemma is that I see that it's possible to modify or move media from within the iMovie application, and therefore break the reference to that media with FCPX.
I only see two options: (1) Never Ever modify the location/name of media in the iMovie Events file (even from within the iMovie app) since I would break an FCPX link if that media is referenced, or (2) always import (copy) the iMovie events into the FCPX Event Library making an independent original so that I can confidently operate on those media files in either application.
I'd surely rather not have to do (2 )(e.g. doubling my storage demands) to gain the flexibility of using either application to edit the video, but really don't want to live with the restrictions of (1).
Thoughts / Solutions? What might you consider as options or best practices?

Unless there is some other reason, users should own the right to share their mailboxes - it shouldn't be something that demands administrator management (if only so that the administrators aren't swamped by user requests for sharing their mailboxes).
For true shared mailboxes, when the mailbox is created, full access is granted by an administrator.
