What does a BI Developer need to know about SAP tables and why?

Hi,
i.
As a BI Developer, to what extent do you need to know about SAP tables?
e.g. if you work mainly in the functional areas LO and FI
ii.
For example, I know that in Finance, GL relates to the tables BSEG and BKPF.
And if it is important to know about them, then which other tables need to be known and for what reasons?
e.g. do I need to know all these tables: http://www.erpgenie.com/sap/abap/tables_fi.htm
iii.
I thought as a BI Developer, knowing that a particular datasource, e.g. 0FI_GL_4 contains line items is enough and you replicate it to BW and work with it. Why is there the need to know the tables from which this datasource gets is data?
iv. What is the main difference between the FI datasources and the LO datasource?
Thanks.

Not required, but today business demands so you required this Knowelgde.

We can't say yes or No, so based on your requirement you need to sit with Functional COnsultanst and the understand the Business Requirements and develop the OBjetcs.

If you want to know the data flow and reconsilization then you need to know it else not required
iv. What is the main difference between the FI datasources and the LO datasource?
Yes, one main difference is There is no setup table concept for FI DataSource*
Note: If you want to become a good BW consulatnt you must know about Tables for normal BW consultant it is not required.

What does a java developer needs to know?

I'm studying "thinking in java", and trying to learn how to make GUI's with swing.
i feel i'm progressing, specially because this is the first programming language i'm studying seriously. i want to work as a java programmer. i want to learn it very well. I got a class about UML, and we are learning the basics using the book of booch, rumbaugh and jacobson. but only the basics(for now). my question is this:
if i want to be a really good java programmer, what else do i have to study?do i have to know UML very well or not? i think it's not enough knowing the language to be able to work and understand it as a whole.i need your help because here in argentina i don't know many java programmers, and i know that there in the USA you got better(and moore) programmers than us(surely you are some of them).
if you know good books, i hear you suggestions too.
i apologize for my english.
Thank you

Just a couple of thoughts:
Firstly, although huge, Thinking in Java (IMHO) is not a good place to start for Swing - it is very light-weight in this area.
I recently started to teach myself Swing and I haven't yet seen a book that has tempted me to part with cash. I followed all the Swing related tutorials, dredged these forums every day, and did a couple of throwaway projects. I am no expert now, but this approach got me through. You can also search the forum for books that others may recommend.
As for other things you need to know - I would say that kind of depends on what you want to do. Do you want to build web-based apps, desktop apps, apps that run on your TV top or in your hand? Give some thought to that and it will help you narrow down the list of complimentary skills you need.
In ANY case, make sure you have a thorough understanding of OOP, go through the Sun tutorials, and get yourself as well-grounded in the basics as you possibly can. You can then move forward.
Good Luck,
Steve

I NEED TO KNOW ABOUT DRIVING TABLE...PLEASE

Well, My name is Adan. I am from Panama.. my english is not
good. But I'll try. I need to know about driving tables and how
have to choose a driving table and how optimizer proccess an sql
statment.
Example:
Employees have (1,000,000 rows),
dept have (100 rows)
Category have (100 rows)...
I need retrieved all employees with category and dept name for
those employee with salary > 100000
Well, What is the driving table and where i have to put this one
in the from clause ? What about order in the where predicate...
First ?
Select E.name, C.category, D.Departement
from Employees e, dept d, category c
where
and d.cat = c.cat
and e.deptno = d.deptno
and e.salary > 100000
Last ?
Select E.name,C.category, D.Departement
from dept d, category c ,Employees e
where
and d.cat = c.cat
and e.deptno = d.deptno
and e.salary > 100000
I apreciate your help....Thanks and sorry for my english....
Bye..

Adam,
If you set your optimizer = choose and analyze the tables and
indexes to generate statistics, then your system can use the
Cost Based Optimizer (CBO) and, like David said, it will
automatically choose the best access path, and the order of
things will not matter.
If your optimizer is not set to choose or if there are no
statistics, then it will use the Rule Based Optimizer (RBO), in
which case, the only thing that matters is the order of the
tables in the from clause. When using RBO, the driving table
should be at the end of the from clause, in the right-most
position. The driving table is the one such that, after the
restrictions have been applied, returns the smallest number of
rows. You would have to compare the number of rows in the
employees table where salary > 100000 to the number of rows in
the dept table (100) and the number of rows in the category
table (100).
In RBO, if there are more than 100 rows in the employees table
where salary > 100000, then your from clause would be:
FROM employees e, dept d, category c
In RBO, if there are less than 100 rows in the employees table
where salary > 100000, then your from clause would be:
FROM category c, dept d, employees e
This is all that applies to the example you have given, however
there are other things that can apply in other situations. For
example, if there is an outer join to a table, the table that
has the (+) cannot be used as the driving table.

Ashok,
Hi! Excellent that you are take the next steps in your education and applying them to work experiences.
The best approach in taking SAP-related courses is to contact the university and confirm their approach. View SAP UA member schools here - http://uaaroundtheworld.informatik.tu-muenchen.de/overview(bD1lbiZjPTEwMQ==)/start.htm
...and assess the ones in the UK which does include Brunel.
Ask if they provide SAP-related curricula (or supplements) and hands on SAP software in this course or others that you can take in your program.
Best regards,
Richard

What does a MAC really need to do justice to FCE and FCEHD?

I need to purchase a new laptop. I want to use it to prepare 45 min documentaries. The original video will have audio filmed with it. I will want to add more narration, music, more photos, ie. the works. I have been using iPhoto and find that video containing audio and background noise, plus added narration, photos, and background music limits me to 20-30 min DVDs before stuttering occurs. What hardware do I need to do a professional job?
G4 Dual 1 GHz BUS 133 MHz using an external hard drive for iMovie Mac OS X (10.4.8) all software updates
G4 Dual Mac OS X (10.3.9) all software updates

Hi(Bonjour)!
A laptop is not for professionnal video editing in a regular basis ( at least in your home editing room).
If you need absolutely the portability, that's Okay, but keep in mind that Hard Drives of laptop are slower than one in desktop machine. An external Hard Drive is recommended.
A desktop machine is less fragile, has more connectors on it and is generally faster that the "laptop" little brother (in a head to head comparaison at the same introducing date, the laptop are one generation behind ).
A desktop machine can be easily upgraded and the parts are less expensive.
A good mic is a must to catch good voice overs.

What do I need to know about field order and HDV?

I keep seeing field order options in FCP and DVDSP and Compressor etc.
Can anyone point me to any resources that will help me understand things a little better?
I'm editing HDV in FCS.
Thanks
Miller.

Field dominance (actually field order) is a function of how video is recorded.
Each frame of interlaced video is made up of two fields. They are recorded in sequence. At NTSC std video (~30fps) the frames are recorded 1/60th of a second apart.
We will call the first field recorded: #1 and the second field: #2.
To play back correctly you need to play the fields in the order they were recorded
if done correctly it would look like this
1-2 1-2 1-2
if the fields are reversed (by using the wrong field order setting) you would get
2-1 2-1 2-1
This yields a jerky, strobe like playback as the fields are being played not in the order they were recorded.
HDV records the Upper field first in each frame and so is termed Upper Dominant
DV record the Lower field first in each frame and is termed Lower Dominant
Questions? There will be a quiz on Monday. And NO, it is not open book.
Cheers,

FAQ: I already have a Revel account. What do I need to do? What do I need to know about this?

Q: I already have a Revel account. What do I need to do? What do I need to know about this?
A: If your Revel account uses the same Adobe ID as your Photoshop.com account, your JPEGs will be moved there. Otherwise, a new Revel account will be set up for you using the same Adobe ID you use with your Photoshop.com account.
Revel accounts can be merged manually. Use the Adobe Media Downloader to download all of the JPEG photos from your Photoshop.com library and then upload those photos to your existing Revel account.
Click here to archive your Photoshop.com library so you do not lose any files.

HT1620 So what do I need to know about using my iPad on public networks, say restaurants,etc. Can I use passwords of any kind, or will I be compromised?

So what do I need to know about using my iPad mini on public networks, say in restaurants. Will I be compromised by using passwords? What protects my iPad?

To date, the iPad/iPad mini/iPhone/iPod Touch produces have remained secure.
In a public place, you do not control the network, so be careful of what activities you perform, such as accessing your bank, or other sensitive places.
Just surfing and reading your email is generally speaking not a problem. Hopefully, your email connections are over secure SSL connections.

What do I need to know about transfering a 4th gen touch to a new 5th gen touch?

My daughter will be getting a new 5th generation touch today. She has a 4th generation touch now. What do I need to know about transfering informaiton from one device to the other?

See:
iOS: Transferring information from your current iPhone, iPad, or iPod touch to a new device
Unless you restore from an encrypted backup, y will have to reenter all password on the new device
iTunes and encrypted backups
You can protect your backup with a passcode using the Encrypt Backup option in the Summary tab. Encrypting your backup will back up your Keychain. This way, your email account passwords, Wi-Fi passwords, and passwords that you enter into websites and some apps will be remembered when you transfer to a new device. Learn how to create and restore from a backup.
When your backup is encrypted, you'll need to enter the password when enabling or disabling encryption or when restoring from the backup.

What do I need to know about fonts?

Can anyone explain what I need to know about using fonts on a MacBook Pro running Leopard, or point me to a good reference or tutorial? I've never paid much attention to fonts in the past, as I only use a few in print (Arial, Verdana, Times New Roman, etc.), and I never did much with fonts in my graphics work. But I want to take a closer look at fonts and start experimenting with them. Looks like a surprisingly big topic.
On my PC, I was limited to how many fonts I could display by memory. As I understand it, there's no such limit on a Mac running Leopard.
I encountered references to fonts when I installed Adobe Creative Suite and Microsoft Office for Mac, so I need to figure out how to manage fonts, then go back and check the installation disks again.
Right now I have three font folders in username > Library: FontCollections, Fonts (empty) and Fonts Disabled (empty).
I also need to learn about the different kinds of fonts (e.g. True Type, etc.) and how/where people obtain them, though that's probably beyond the scope of this thread.
But before I do any more research via Google, I'd like to narrow the field a bit. I was hoping someone could give me a basic overview or point me to a good reference. What software do you use to manage fonts on a Mac, and do you have any basic tips to offer?
Thanks.

Downgrade Lion/Mountain Lion to Snow Leopard
1. Boot from your Snow Leopard Installer Disc. After the installer
      loads select your language and click on the Continue
      button. When the menu bar appears select Disk Utility from the
      Utilities menu.
2. After DU loads select your hard drive (this is the entry with the
      mfgr.'s ID and size) from the left side list. Note the SMART status
      of the drive in DU's status area. If it does not say "Verified" then
      the drive is failing or has failed and will need replacing. SMART
      info will not be reported on external drives. Otherwise, click on
      the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions
      from the drop down menu to one. Set the format type to Mac OS
      Extended (Journaled.) Click on the Options button, set the
      partition scheme to GUID then click on the OK button. Click on
      the Partition button and wait until the process has completed.
4. Quit DU and return to the installer. Install Snow Leopard.
This will erase the whole drive so be sure to backup your files if you don't have a backup already. If you have performed a TM backup using Lion be aware that you cannot restore from that backup in Snow Leopard (see below.) I suggest you make a separate backup using Carbon Copy Cloner.
If you have Snow Leopard Time Machine backups made while on Snow Leopard, then you may do a full system restore per #14 in Time Machine - Frequently Asked Questions. If you have subsequent backups from Lion, you can restore newer items selectively, via the "Star Wars" display, per #15 there, but be careful; some Snow Leopard apps may not work with the Lion/Mountain Lion files.

For what does the BPEL Manager need a domain ?

For what does the BPEL engine need a domain ?
Where (in which file) is specified to which domain the BPEL Manager
connects to?
Is it a difference if the domains are defined in table
orabpel.domain
or just
domain
? With which user/password/service does to BPEL Manager connect to
Oracle DB to search for its domain?
Background: My domain "default" exists in table but BEPL Manager could not connect here

We currently have 3 domains for BPEL. We use them because they a) serve different purposes, b) we tweak the domain level threads.
I believe bpel manager will, by default, connect to the which ever domain starts with the letter closest to A.
I also think the user account is orabpel, which connects to the bpel schema.
