Best Practice for enhancing the SAP delivered standard WD ABAP application

Hi,
I am new to WebDypro ABAP.
To enhance the SAP delivered Standard WebDynpro Component (complex component with Business objects & powl).
Kindly let me know the best practice for enhancing the Standard WD ABAP from the below 1 or 2.
1) To copy & create a "Z" of the component & make changes in that (or)
2) to enhance directly on the same standard component without making "Z".
Regards,
NS

Hi NS,
If it is a standard component its better we go for enhancing the component rather than copying it into Z component.
If there is any issue with in the standard component , SAP supports it through notes and OSS messages. If it is a Z component, SAP doesn't support it.
If there is any up gradation of business packages, changes will be done to standard , but not the Z components, wherein we could miss it.
Further, since it is a standard component it might have been used at many places, changes that has to done to reflect all changes might be difficult in this case if it is a z component.

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.

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

Best practices for using the knowledge directory

Anyone know when it is best to store docs in the Knowledge Directory versus Collab? They are both searchable, but I guess you can publish from the Publisher to the KD. Anyone have any best practices for using the KD or setting up taxonomies in the KD?

Hi Richard,
If you need to configure dynamic pricing that may vary by tenant and/or if you want to set up cost drivers that are service item attributes, you should configure Billing Tables in the Demand Management module in 10.0.
The cost detail functionality in 9.4 will likely be changed to merged with the new pricing feature in 10.0. The current plan is not to bring cost detail into the Service Catalog module.

Best practices for using the 'cost details' fields

Hi
Please could you advise us to the best practices for using the 'cost details' field within Pricing. Currently I cannot find the way to surface the individual Cost Details fields within the Next Generation UI, even with the tick box for 'display both cost and price' ticked. It seems that these get surfaced when the Next Generation UI is turned off, but cannot find them when it is turned on. We can see the 'Pricing Summary' field but this does not fulfill our needs, as some of our services have both recurring and one-off costs.
Attached are some screenshots to further explain the situation.
Many thanks,
Richard Thornton

What are the best practices for using the enhancement framework?

Hello enhancement framework experts,
Recently, my company upgraded to SAP NW 7.1 EhP6. This presents us with the capability to use the enhancement framework.
A couple of senior programmers were asked to deliver a guideline for use of the framework. They published the following statement:
"SAP does not guarantee the validity of the enhancement points in future releases/versions. As a result, any implemented enhancement points may require significant work during upgrades. So, enhancement points should essentially be used as an alternative to core modifications, which is a rare scenario.".
I am looking for confirmation or contradiction to the statement "SAP does not guarantee the validity of enhancement points in future releases/versions..." . Is this a true statement for both implicit and explicit enhancement points?
Is the impact of activated explicit and implicit enhancements much greater to an SAP upgrade than BAdi's and user exits?
Is there any SAP published guidelines/best practices for use of the enhancement framework?
Thank you,
Kimberly

Best Practices for Accessing the Configuration data Modelled as XML File in

Hi,
I refer the couple of blof posts/Forum threads on How to model and access the Configuration data as XML inside OSB.
One of the easiest and way is to
Re: OSB: What is best practice for reading configuration information
Another could be
Uploading XML data as .xq file (Creating .xq file copy paste all the Configuration as XML )
I need expert answers for following.
1] I have .xsd file which is representing the Configuration data. Structure of XSD is
<FrameworkConfig>
<Config type="common" key="someKey">proprtyvalue</Config>
<FrameworkConfig>
2] As my project will move from one env to another the property-value will change according to the Environment...
For Dev:
<FrameworkConfig>
<Config type="common" key="someKey">proprtyvalue_Dev</Config>
<FrameworkConfig>
For Stage :
<FrameworkConfig>
<Config type="common" key="someKey">proprtyvalue_Stage</Config>
<FrameworkConfig>
3] Let say I create the following Folder structure to store the Configuration file specific for dev/stage/prod instance
OSB Project Folder
|
|---Dev
|
|--Dev_Config_file.xml
|
|---Stage
|
|--Stahe_Config_file.xml
|
|---Prod
|
|-Prod_Config_file.xml
4] I need a way to load these property file as xml element/variable inside OSb message flow.?? I can't use XPath function fn:doc("URL") coz I don't know exact path of XMl on deployed server.
5] Also I need to lookup/model the value which will specify the current server type(Dev/Stage/prod) on which OSB MF is running. Let say any construct which will act as a Global configuration and can be acccessible inside the OSb message flow. If I get the vaalue for the Global variable as Dev means I will load the xml config file under the Dev Directory @runtime containing key value pair for Dev environment.
6] This Re: OSB: What is best practice for reading configuration information
suggest the designing of the web application which will serve the xml file over the http protocol and getting the contents into variable (which in turn can be used in OSB message flow). Can we address this problem without creating the extra Project and adding the Dependencies? I read configuration file approach too..but the sample configuration file doesn't show entry of .xml file as resources
Hope I am clear...I really appreciate your comments and suggestion..

If you can enforce some sort of naming convention for the transport endpoint for this proxy service across the environments, where the environment name is part of the endpoint you may able to retrieve it from $inbound in the message pipeline.
eg. http://osb_host/service/prod/service1 ==> Prod and http://osb_host/service/prod/service2 ==> stage , then i think $inbound/ctx:transport/ctx:uri can give you /service/prod/service1 or /service/stage/service1 and applying appropriate xpath functions you will be able to extract the environment name.
Chk this link for details on $inbound/ctx:transport : http://download.oracle.com/docs/cd/E13159_01/osb/docs10gr3/userguide/context.html#wp1080822

Best practice for keeping a mail session open in web application?

Hello,
We have a webmail like application where users login with their IMAP credentials, then are taken to an authenticated area of the site where they can manage different things about their email account.
Right now the application is opening and closing a mail store connection (via a new javax.mail.Session) for each page load based on the current logged in user credentials. To me this seems like it would be a bad practice to keep opening and closing a connection each page load.
Are there any best practices for this situation? It would be nice to be able to open the connection to the mail server on login, then keep that connection open until the person logs out, session expires, etc.
I can probably put the javax.mail.Session into the HTTP session, but that seems like it would break any clustering functionality of tomcat. This would be fine if the machine the user is on didn't fail, but id assume if they failed over to another the mail session would be gone. Maybe keeping the mail session in the http session, checking for a connection, then first attempting to reconnect with the logged in credentials before giving up would be a possiblity?
Any pointers would be appreciated

If you keep the connection open across pages, you're going to need to deal with
timeouts - from the http session and from the mail server.
If you don't keep the connection open, you're going to need to "resynchronize"
your view of the store/folder with each operation, in case the folder is modified
by another session.
The former is easier in the common cases, especially if you don't care how gracefully
you handle failures. The latter is more difficult in the common cases, but handles
failure better, and in particular handles clustering better. You'll need to measure it to
see if it meets your performance and scalability requirements. You may need to mix
the two approaches to get acceptable performance.

Best practice for deletion of SAP standard configuration

Does anyone have any documentation related to deletion of standard SAP configuration? My client is requesting deletion of all the standard delivered company codes and I believe it is best practice to never delete them. I am looking for supporting documentation that supports this.

Rhonda,
I have never seen a system where the standard delivered company codes did not exist, so I can't say what the implications of deletion are. I suppose it is possible to do....
For documentation, I guess you could search through service.sap.com/support.
I would think you would respond to the request as follows:
Tell the client it will be extra work to delete the items. Which will translate into additional billable fees.
Tell the client (in writing) that you cannot predict what all possible outcomes will be, but that you are willing to work with him to fix anything that gets broken in the process. For additional billable fees.
In the end, the client is paying for your advice and your services. In the end, he owns the license and the system upon which it is running. He can have anything he wants, there is no other 'right' or 'wrong'.
I suggest you don't delete anything in client 000. Most companies keep this as a reference. If the client later decides to reconstruct, this would be a nice source of info.
Since company codes greatly affect FI/CO, you might want to post the question in one of those forums.
Best Regards,

"best practice to maintain the SAP OM Org Structure"

Hi SAP Experts,
My client want to have an best practice or an safe process to update, better and maintain their existing SAP HCM Organizational Structure. In one way you can say that i am doing an process oriented job.
Our client system is not up-to-date due to the lack of user awareness and complete knowledge on the system. Due to this they are unsure on the accuracy of the reports that comes out of the system.
As a HCM functional consultant i can look from the technical perspective but not on this process oriented role. I need your guidance in this regard, please sugguest me how can i move ahead and make some really valuable recommendations ? I am confused on where to start and how to start. Please help me in this regard.
Thanks in advance,

Best practices for making the end result web help printable

Hi all, using TCS3 Win 7 64 bit. All patched and up to date.
I was wondering what the best practices are for the following scenario:
I am authoring in Frame, link by reference into RH.
I use Frame to generate PDFs and RH to generate webhelp.
I have tons of conditional text which ultimately produce four separate versions of PDFs as well as online help - I handle these codes in FM and pull them into RH.
I use a css on all pages of my RH to make it 'look' right.
We now need to add the ability for end users to print the webhelp - outside of just CTRL+P because a)that cuts off the larger images and b)it doesn't show header, footer, logo, date, etc. (stuff that is in the master pages in FM).
My thought is doing the following:
Adding four sentences (one for each condition) in the FM book on the first page. Each one would be coded for audience A, B, C, or D (each of which require separate PDFs) as well as coded with ONLINE so that they don't show up in my printed PDFs that I generate out of Frame. Once the PDFs are generated, I would add a hyperlink in RH (manually) to each sentence and link the associated PDF (this seems to add the PDF file to the baggage files in RH). Then when I generate my RH webhelp, it would show the link, with the PDF, correctly based on the condition of the user looking at the help.
My questions are as follows:
1- This seems more complicated than it needs to be. Is it?
2- I would have to manually update every single hyperlink each time I update my FM book, because I am single sourcing out of Frame and I am unable (as far as I can tell) to link a PDF within the frame doc. I update the entire book (over 1500 pages) once every 6 weeks so while this wouldn't be a common occurrence it will happen regularly, and it would be manual (as far as I can tell)?
3- Eventually, I would have countless PDFs inside RH. I assume this will eventually impact performance. So this also doesn't seem ideal?
If anyone has thoughts/suggestions on a simpler way or better way to do this, I'd certainly appreciate it. I have watched the Adobe TV tutorial on adding a master page but that seems to remove the ability to use a css across all my topics and it also requires the manual addition of a manual hyperlink to the PDF file, so that is what I am proposing above, anyway (not sure the benefit, therefore).
Thanks in advance,
Adriana

Anything other than CTRL + P is going to create a lot of work so perhaps I can comment on what you see as drawbacks to that.
a)that cuts off the larger images and b)it doesn't show header, footer,
logo, date, etc. (stuff that is in the master pages in FM).
Larger images.
I simply make a point of keeping my image sizes down to a size that works. It's not a problem for me but that doesn't mean it will work for you. Here all I am doing is suggesting you review how big a problem that would be.
Master Page Details
I have to preface this with the statement that I don't work with FM. The details you refer to print when they are in RoboHelp master pages. Perhaps one of the FM users here can comment on how to get FM master pages to come through.

Best practice for replicate the IDM (OIM 11.1.1.5.0) environment

Dear,
I need to replicate the IDM production to build the IDM test environment. I have the OIM 11.1.1.5.0 in production with lots of custom codes.
I have two approaches:
approach1:
Manually deploy the code through Jdeveloper and export and import all the artifacts. Issue is this will require a lot of time and resolving dependencies.
approach2:
Take the OIM, MDS and SOA schemas export and Import the same into new IDM Test DB environment.
could you please suggest me what is the best practice and if you have some pointers to achieve the same.
Appreciate your help.
Thanks,

Follow your build document for the same steps you used to build production.
You should know where all your code is. You can use the deployment manager to export your configurations. Export customized files from MDS. Just follow the process again, and you will have a clean instance not containing production data.
It only takes a lot of time if your client is lacking documentation or if you re not familiar with all the parts of the environment. What's 2-3 hours compared to all the issues you will run into if you copy databases or import/export schemas?

2K8 - Best practice for setting the DNS server list on a DC/DNS server for an interface

We have been referencing the article
"DNS: DNS servers on <adapter name> should include their own IP addresses on their interface lists of DNS servers"
http://technet.microsoft.com/en-us/library/dd378900%28WS.10%29.aspx but there are some parts that are a bit confusing. In particular is this statement
"The inclusion of its own IP address in the list of DNS servers improves performance and increases availability of DNS servers. However, if the DNS server is also a domain
controller and it points only to itself for name resolution, it can become an island and fail to replicate with other domain controllers. For this reason, use caution when configuring the loopback address on an adapter if the server is also a domain controller.
The loopback address should be configured only as a secondary or tertiary DNS server on a domain controller.”
The paragraph switches from using the term "its own IP address" to "loopback" address. This is confusing becasuse technically they are not the same. Loppback addresses are 127.0.0.1 through 127.255.255.255. The resolution section then
goes on and adds the "loopback address" 127.0.0.1 to the list of DNS servers for each interface.
In the past we always setup DCs to use their own IP address as the primary DNS server, not 127.0.0.1. Based on my experience and reading the article I am under the impression we could use the following setup.
Primary DNS: Locally assigned IP of the DC (i.e. 192.168.1.5)
Secondary DNS: The assigned IP of another DC (i.e. 192.168.1.6)
Tertiary DNS: 127.0.0.1
I guess the secondary and tertiary addresses could be swapped based on the article. Is there a document that provides clearer guidance on how to setup the DNS server list properly on Windows 2008 R2 DC/DNS servers? I have seen some other discussions
that talk about the pros and cons of using another DC/DNS as the Primary. MS should have clear guidance on this somewhere.

Actually, my suggestion, which seems to be the mostly agreed method, is:
Primary DNS: Locally assigned IP of the DC (i.e. 192.168.1.5)
Secondary DNS: The assigned IP of another DC (i.e. 192.168.1.6)
Tertiary DNS: empty
The tertiary more than likely won't be hit, (besides it being superfluous and the list will reset back to the first one) due to the client side resolver algorithm time out process, as I mentioned earlier. Here's a full explanation on how
it works and why:
This article discusses:
WINS NetBIOS, Browser Service, Disabling NetBIOS, & Direct Hosted SMB (DirectSMB).
The DNS Client Side Resolver algorithm.
If one DC or DNS goes down, does a client logon to another DC?

I agree with this proposed solution as well:
Primary DNS: Locally assigned IP of the DC (i.e. 192.168.1.5)
Secondary DNS: The assigned IP of another DC (i.e. 192.168.1.6)
Tertiary DNS: empty
One thing to note, in this configuration the Best Practice Analyzer will throw the error:
The network adapter Local Area Connection 2 does not list the loopback IP address as a DNS server, or it is configured as the first entry.
Even if you add the loopback address as a Tertiary DNS address the error will still appear. The only way I've seen this error eliminated is to add the loopback address as the second entry in DNS, so:
Primary DNS: The assigned IP of another DC (i.e. 192.168.1.6)
Secondary DNS: 127.0.0.1
Tertiary DNS: empty
I'm not comfortable not having the local DC/DNS address listed so I'm going with the solution Ace offers.

Best practice for deploying the license server

Was wondering if there is a best practice guideline or a rule of thumb out there for deploying the license server. For instance, is it better to have one license server and all your products connect to that, dev, QA, prod. Or is it better to have a license server for each deployment, i.e. one for dev one for QA.. etc.
