When asking database related questions, please give other posters
some clues, like OS (with version), version of Oracle being used and DDL.
Other trivia such as CPU, RAM + Disk configuration might also be useful.
The exact text and/or number of error messages is useful (!= "it didn't work!"). Thanks.

Difference between Web Services and RFC (both Advantages & Disadvantage)

Hi All,
will you please explain the difference between Web Services and RFC (both Advantages & Disadvantage)
Thanks,
jyothi.

Hi,
If you want have a communications between SAP systems within a network, we can go for an RFC.
If you want have communication between SAP systems through a medium like internet, we can probably go for a webservice.
Please refer the following links:
What is the difference between RFC vs. Web service ?
Webservice
If you want to convert an RFC fuction module to an webservice, you can refer the following link,

What are the advantages/disadvantages of using PS/CS5 in 64bit over 32bit please?

What are the advantages/disadvantages of using PS/CS5 in 64bit over 32bit please?

From a practical perspective, besides the 64 bit version being a bit faster at just about everything, limitations on document size are lifted in the 64 bit version. Essentially, how much can do is limited only by how much RAM you have installed in your system. You can do things like have larger documents, deeper history, etc. and have it all work quickly.
On the other hand, many 3rd party plug-ins, especially older ones, only provide 32 bit versions, which will only run in 32 bit Photoshop.
Both 32 and 64 bit versions are installed by default. It's important to note that most of the preferences are separate between the two, so you can have two slightly different setups that might help with specialty operations you might need. This gets pretty subtle, but for example I keep the 32 bit version configured with only 1 cache level, so all previews of high bit depth images are always composited in high bit depth. This aids me with some aspects of astroimage processing. It's slower, but more accurate. By contrast I have more cache levels configured for my 64 bit version, so that's faster for general photography work.

Advantages & disadvantages with embedded, external use of sub reports

Hi Guys,
I have a Question on "re-import subreport when open" option, which is available for sub report and it will reimport the sub report every time when we open the main report.
With that option we can see every modification until when we open that report.
My question is, does we have any document which specifies the Advantages & disadvantages of using Embedded, external(re-import) subreports in Main reports.
And i have one more scenario, i have a subreport which is used in ten reports. In every report i am taking the same Sub report from shared location and check the option "reimport subreport when open". So when i apply any change that change will applied for all ten reports at my next schedule.
My Question is: if the Subreport executes 10 minutes and i scheduled all the 10 main reports at a time. At that time does the sub report lock for one report or it will use for all the 10 reports? Can anyone give brief explanation about this?
Regards,
Naga.

hi Naga,
the only advantage to this feature is that changes are reflected when opening your report. that's it....useful for changes when you're in dev mode. disadvantage may be slight loss of speed vs. just embedding the subeport and then manually reimporting.
the second question should probably be directed to the bi platform and not in cr design as you're scheduling.

What is the advantages/disadvantages of using BPEL only without BAM?

What is the advantages/disadvantages of using BPEL only without BAM, and the combination for Error and Exception management in SOA?
Please let me know if anybody had this experience?

Hi,
Both variants have pro's and cons. If you plan to use VBA you have to consider the deployment settings on other p.c.'s where you have to allow macro's where as a regular form doesn't have the need for that.
That said the userform gives you much more control because the form command is not saved. it is simply a temporary form which you have to setup every time. It's perfect for data entry. If you are looking for data validation the userform is the one to go
for. You also have the possibility to work on placements of the data entry.
So if you are looking for speed and simplicity then go for the form command. If it is handling control you are after I'd go for a userform.

SAXParser
Both DOM and SAX approaches have advantages and disadvantages, and your choice of technique must depend on the type of data being parsed, the requirements of your application, and the constraints under which you are operating.
The SAX approach is linear: It processes XML structures as it finds them, generating events and leaving the event handlers to decide what to do with each structure. The advantage of this approach is that it is resource-friendly; because SAX does not build a tree representation of the document in memory, it can parse XML data in chunks, processing large amounts of data with very little impact on memory. This also translates into better performance; if your document structure is simple, and the event handlers don't have anything too complicated to do, SAX-based applications will generally offer a speed advantage over DOM-based ones.
The downside, though, is an inability to move around the document in a non- linear manner. SAX does not maintain any internal record of the relationships between the different nodes of an XML document (as the DOM does), making it difficult to create customized node collections or to traverse the document in a non-sequential manner. The only way around this with SAX is to create your own custom object model, and map the document elements into your own custom structuresa process that adds to complexity and can possibly degrade performance.
Where SAX flounders, though, the DOM shines. The DOM creates a tree representation of the document in memory, making it possible to easily travel from one node to another, or even access the same node repeatedly (again, not something you can do easily in SAX). This tree representation is based on a standard, easy-to-understand model, making it easier to write code to interact with it.
This flexibility does, however, come with an important caveat. Because the DOM builds a tree in memory, DOM processing cannot begin until the document has been fully parsed (SAX, on the other hand, can begin parsing a document even if it's not all available immediately). This reduces a developer's ability to "manage" the parsing process by feeding data to the parser in chunks, and also implies greater memory consumption and consequent performance degradation.
Consequently, the choice of technique depends significantly on the type of constraints the application will be performing under, and the type of processing it will be expected to carry out. For systems with limited memory, SAX is a far more efficient approach. On the other hand, complex data-processing requirements can benefit from the standard object model and API of the DOM.
After using DOM to parse XML documents for any length of time, you will probably begin to notice that performance tends to suffer when youre dealing with large documents. This problem is endemic to DOM's tree-based structure: larger trees demand more memory, and DOM must load an entire document into memory before it can allow you to parse it. For situations where performance is problematic with DOM, you have an alternative in the Simple API for XML (SAX). In this fifth installment in our Remedial XML series, I'll introduce you to the SAX API, and provide some links to SAX implementations in several different languages.

Difference between lsmw using BAPI & lsmw using IDOC?

HI everybody
can anybody tell me difference between lsmw using BAPI & lsmw using IDOC?

IDocs and BAPI are very different, so it should be easy to choose between them depending on your requirements.
IDOCS
Advantages
System can work even if target system not always online. The IDoc will be created and sending will just continue once you get connected to the other system.
No additional programming required. You just need to set up the configuration.
Disadvantages
Receipt/processing on the target system may not be immediate.
The sending system has no way to know whether the target system actually received what you sent (unless you use ALE).
If there is no SAP standard IDoc available for your requirement, it's harder to create a customized IDoc than a customized BAPI.
BAPIS
Advantages
You can tell if your sending was successful or not
Sending to/processing on the other side is immediate
Easier to create your own BAPI than your own IDoc
Disadvantages
Will only work if you have an active online connection.
Some programming required to call the BAPI.
Others interface methods you might also want to consider are ALE and RFCs.

Advantages & Disadvantages of RAID and How affect Qosmio G30 speed

Hi.
i heard that setting RAID can increase or not speed.. can anyone more expert explain me how this works?
1.) First of all what is RAID (explain in words that an ignorant in computing like me can uderstand)
2.) What's the difference between raid 0 or raid 1 and how it affect the computer?
3.) What are the advantages/disadvantages choosing between this two settings?

Hi
Im not a RAID guru ;) but I have used the Qosmio G20 with and without enabled RAID technology and I did not notice any speed disadvantages.
I see you are a newbie and therefore I will try to explain the RAID functionality very easily ;)
So what is RAID? RAID (Redundant Array of Independent Disks) helps to save data.
The RAID mirrors the content of the first HDD to the second HDD. That means that all files (depending on the RAID settings) which are stored on the HDD1 are also stored on HDD2. If the HDD1 will damage, you will be able to recover the whole content from the HDD2.
The two HDDs can be used with RAID-1 mirroring or RAID-0 stripping
When using RAID-1 the data is stored twice (once on each of the HDDs) so if there are problems with one of the HDDs, the other HDD can be used to recover the data.
But you can use the both HDDs only as a single HDD. (2 HDDs = 1 HDD)
When using RAID-0 (stripping) the size seen by the OS is twice!
Using the RAID-0 configuration, all data on both disks will be lost, even if only one of the two disks fails!!!
I think the RAID is very useful because it safes the HDD content!
Of course, if you use the mirroring option you can use only the one available HDD!!!
But you are on the safe site ;)

What are the advantages of using Map IDs?

Hi:
I am trying to find out the advantages for using map ids as
opposed to just using the file names for the topics, but I couldn't
find this information in the RH7 Help or the forums. Can you please
list the advantages and disadvantages.
Also, I am describing how I wish to implement the context
sensitive help feature for my application and you can tell me which
approach is better. We make an application that is packaged within
a Java IDE. We want to launch context sensitive help topics from
the wizards and cheat sheets. Now, this context sensitive help can
be either be installed on the local machine or network (file://
protocol) or available on our portal (https:// protocol). We do
have the infrastructure in place to let the user decide whether
he/she wants to access the local help topic or the one over the
internet. Will map ids work for both the scenarios?
Thanks,
K

It sounds like your application call needs to call an online
version of the help first and if this is not available to point to
a local copy. Is that right? If so, how this happens is entirely in
the hands of your developers. I know it can be done, just sketchy
on the actual procedure.
As far as the CSH in the help is concerned, you can use
mapids for both versions of the help if you want. If using webhelp
you'd do well to check out
this
link on Peter Grainge's site.

Advantages of using XI in Vendor portal (webdynpro) development

Hi,
I will be greatful if anyone provide the advantages/disadvantages of using XI in vendor portal development. I need this information for my presentation to my client. I need it in urgent. Thanks in advance.

ITS will be much handy when you want to display standard SAP transaction in portal/browser frontend.
with ITS , you can expose the transaction to web with zero coding, but had to live with the limitation of not being able to change the look and feel much.
whereas if youdecide to program the entire transaction yourself for the web, it will be really time consuming and sometime may not be able to provide the same look and feel and functionality which sap win/web gui offers.

Advantages of using PI 7.1 over PI 7.0

Hi All,
I need to suggest to my client, the advantages of using PI 7.1 over PI 7.0, so that we can use the same for our development.
Please dont send me the links from SDN, just suggest the advantages.
Useful answers will be rewarded.
Regards
Ranjit

Hi,
PI 7.1 will be in rampup then - not global availibility
when it will be available you will get an upgreade guide as always
Currently PI 7.0 is only available for real time implementation. You could have the version of PI 7.1 from SDN, but that not for the real time implementation. Its limited only for individual usage.
There is huge difference between PI 7.0 and PI 7.1.
1. PI 7.0 is the part of Netweaver 2004s and PI 7.1 is key entity in eSOA.
2. PI 7.1 have various mapping Enhancements as well as reusability of UDFs across the mappings etc. which is not available in PI 7.0
/people/william.li/blog/2008/01/02/sap-pi-71-mapping-enhancements-series-share-user-defined-functions
3. PI 7.1 comes with the concept of folders for more flexibale and Organized way of developements.
/people/william.li/blog/2007/08/07/using-folders-in-pi-71 -- Folders in PI 7.1
4. Advanced adapter engine is used in PI 7.1, which have overcome the various communication related limitations of previous versions

1. SQL Server is only Windows, but Oracle runs on almost all Platforms.
2. You can have multiple databases in SQL Server, but Oracle provides you only one database per instance.Given that the very term 'database' has s different meaning in the two products, this "difference" is absolutely meaningless.
3. SQL Server provides T-SQL for writing programs, whereas Oracle provides PL/SQLWhich means what? Both products have a procedural programming language. They named them differently, and the languages are not interchangeable. Means nothing in comparing the features/strengths/weaknesses/suitability to purpose.
4. Backup types in both are the same. (Except Oracle provides an additional backup called Logical Backup.)You make that sound like "Logical Backup" is something more than it is. It is nothing more than an export of the data and metadata. Many experts don't even consider it a backup. I'm sure SQL Server provides the same functionality though they probably call it by some other name.
5. Both provide High Availability.Well, I guess they both have a suite of features they refer to as "High Availability". But what does that really mean? The devil is in the details. Remember, the two products don't even agree on what constitutes a "database".
6. Both come in various distributions.???

If you are going for an Implementation, you can try SQL Server Express Edition and Oracle XE which are free to use.
Then you can choose whichever is comfortable for your needs.
