Can somebody teach me some basic knowledge about SD?

I work in BW but I have to know some basic knowledge about SD that are listed below:
How to create a sales order?
what is sales organization?
what is sold to party and many more if you have any links for this kind of information please let me know.
Thanks in advance.
York

Hai Les York,
What you want to know is a vast subject and it will be better to sit with any SD consultant and know all you want. I can do that if you are in Hyderabad.
To briefly tell you what you wanted is:
A Sales Organization is the highest organizational element in any Sales Department of a Company and it is responsible for all the sales activity of that company.
A Sold-to-Party (SP) is non other than your basic Customer. We call him so because he may have a different place where sometimes we have to give deliveries and that place / department will be called as a Ship to Party (SH) of our SP. Like wise if you have a different place to send the Invoice of that SP, then that department will be known as the Bill to Party (BP) for this SP. And if some body other than our SP is paying, then he will be our Payer (PY).
Now to make a Sales Order, go to T Code - VA01, enter, enter your Sales Document Type and your Sales Organization, Distribution Channel, your Division and hit enter, now enter your SP no., and your customer's PO no., and the Material(s) and their respective quantities and if all the basic customization has been done correctly, you will get the Price, Plant, Storage Location, etc., and you can save it.
Then you do your Delivery and finally the Billing depending on your client's buiseness process.
SAP help desk is the best place to help you with all your queries regarding SAP - SD, for Sales Documents I can give you this link, remove all the spaces and use it.

Need some FI functional basic knowledge for BI/FICO reporting?

Hi experts,
I create FI reports using SAP BI, I need your help to learn some basics about FICO to talk in my interview. I know all the FICO table but may be they will ask me about some functional question about FICO and SD modules. Please share some knowledge about these modules. I have very less time and can't able to read the FICO book at this time.
Thanks in advance.

Some basic questions on HANA

Hi All,
I have some basic questions on SAP HANA,
I heard from one of my colligues that it is mandatory to learn SQL scripts for HANA, is it true?
Or basic knowledge is enough for HANA???
Is it added advantage while working on HANA or can we manage with basic knowledge of SQL???
I tried to find answers for these questions in SCN, but I could not get proper answers, So could you please provide answers for above my questions.
Thanks in advance,
Venkat Kalla

Hi Vladmir,
SAP HANA is a platform and is more than just database. Which can serve both OLTP and OLAP.
But since it is a database, Sp SQL skills helps you while modelling in SAP HANA. So When will it be helpful ? It is while addressing some complex requirements using SAP HANA.
At the end of the day, when you want to work in HANA ( a super duper database ) and you still thinking of whether to learn SQL or not?

Need answers for some basic question

The Informatica server software usually runs on some server machine.The client tools usually run on those Windows PC with which developers to their work. That's a pretty much standard client/server architecture.On Windows servers you will often (not always) find the client tools as well, but that's by no means mandatory.Communication between PowerCenter clients and PowerCenter server usually takes place via TCP/IP; the protocol, as far as I know, has been developed by Informatica in-house app. in 1993-1995. The installation of the server software usually is the task of some server administration team. You will also need some DBA team because the Informatica software (almost) always stores its controlling, scheduling, and runtime information in some relational database system. Importing of relational structures (meaning table and view structures) usually is done on a client PC which connects to the respective source and/or target DBMS via ODBC.The server uses either native database client installations (for Oracle, IBM DB2, Microsoft SQL Server, and Sybase) or ODBC to communicate with the source / target databases. Best thing is that you download the documentation and start browsing the Installation and Configuration Guide; this PDF file explains quite a few concepts fairly well. Regards,Nico

Hi, 1) a server installation is a server installation and nothing else. It also contains some clients (namely the command-line client tools), but definitely not the GUI clients (this is an extra installation always to be done on a Windows PC as of this time).2) That depends on your business processes. Sometimes files will be placed in some directory (e.g. /opt/transfer/inp) and then the respective workflow shall start, so it might read this file directly. If some business user can only deliver via email, then you will need an extra process which extracts the file(s) from the email and places them somewhere where the server processes can access them.3) Unix is a computer operating system. Windows is a computer operating system. They are just in use in different cases (at least often). Some basic Unix knowledge (about the most common system tools and a bit of shell scripting) is definitely useful / necessary if you want to work with Unix systems.4) A data warehouse stores information which usually is needed for enterprise-wide strategic business decisions. A server is a machine offering software services. One kind of servers are database servers, and data warehouses usually (not always) are stored in a databases. So some sort of server is the technical basis for a data warehouse.5) Usually these two terms are identical in meaning.6) Unix is an operating system. A shell is a program which enables you to interact with a Unix system. Shell scripting means that you automate moderately complex or highly complex tasks using a programming language which is provided by the shell. Different shells offer different scripting facilities and features. Writing a shell script is a matter of programming. Your questions are by no means stupid. They just show that you still have a lot to learn, but that's ok, we all should try to learn more as long as we live. Regards,Nico

Storage rules for an editing rig. Some basics.

How do you set up your editing machine in terms of disks for maximum performance and reliability? (SSD's are left out here.)
This is a question that often arises and all too often one sees that initial settings are really suboptimal. These rules are intended to help you decide how to setup your disks to get the best response times. Of course the only disks in an editing machine must be 7200 RPM types or faster. No GREEN disks at all.
Rule 1: NEVER partition a disk. You may ask why? First of all, it does not increase disk space, it just allocates the space differently. However, the major drawback is that for a partitioned disk the OS must first access a partition table at the beginning of the disk for all accesses to the disk, thus requiring the heads to move to the beginning of the disk, then when it has gotten the partition info move to the designated area on the disk and perform the requested action. This means much more wear-and-tear on the mechanics of the disk, slower speeds and more overhead for the OS, all reducing efficiency.
Rule 2: Avoid using USB drives, since they are the slowest on the market. Do not be tricked by the alleged bandwidth of USB 2.0 advertisements, because is just is not true and remember that the alleged bandwidth is shared by all USB devices, so if you have a USB mouse, keyboard, printer, card reader or whatever, they all share the bandwidth. Stick to SCSI or SATA disks or e-SATA. If needed, you can use Firewire-800 or even Firewire-400 disks, but they are really more suited for backups than for editing.
Rule 3: Use at least 3 different physical disks on an editing machine, one for OS/programs, one for media and one for pagefile/scratch/renders. Even on a notebook with one internal drive it is easy to accomplish this by using a dual e-SATA to Express card connector. That gives you an additional two e-SATA connections for external disks.
Rule 4: Spread disk access across as many disks as you have. If you have OS & programs on disk C:, set your pagefile on another disk. Also set your pagefile to a fixed size, preferably somewhere around 1.5 times your physical memory.
Rule 5: Turn off index search and compression. Both will cause severe performance hits if you leave them on.
Rule 6: If the fill rate on any of your SATA disks goes over 60-70% it is time to get a larger or an additional disk.
Rule 7: Perform regular defrags on all of your disks. For instance, you can schedule this daily during your lunch break.
Rule 8: Keep your disks cool by using adequate airflow by means of additional fans if needed. You can use SMART to monitor disk temperatures, which should be under 35 degrees C at all times and normally hover around 20-24 C, at least in a properly cooled system.
Rule 9: If people want raid, the cheapest way is to use the on-board IHCR or Marvell chip, but it places a relatively high burden on the CPU. The best way is a hardware controller card, preferably based on the IOP348 chip. Areca ARC and ADAPTEC come to mind. 3Ware uses it's own chipset and though not bad, they are not in the same league as the other two. Promise and the like in the budget range are no good and a complete waste of money. Expect to spend around $ 800 plus for a good controller with 12 connectors internally and 4 e-SATA connectors. Important to consider in a purchasing decision is whether the on-board cache memory can be expanded from the regular 256/512 MB to 2 or even 4 GB. Be aware that 2 GB cache can be relatively cheap, but the 4 GB version extremely costly ($ 30 versus $ 300). For safety reasons it is advisable to include a battery backup module (BBM).
Rule 10: If you can easily replace the data in case of disk failure (like rendered files), go ahead and use raid0, but if you want any protection against data loss, use raid 3/5/6/10/30/50. For further protection you can use hot spares, diminishing downtime and performance degradation.
In general when you get a new disk, pay close attention to any rattling noise, do perform regular disk checks, and in case of doubt about reliability, exchange the disk under guarantee. Often a new disk will fail in the first three months. If they survive that period, most of the disks will survive for the next couple of years. If you use a lot of internal disks like I do (17), set staggered spin-up to around 1 second to lessen the burden on the PSU and improve stability.
Hope this helps to answer some basic questions. If not, let me know. Further enhancements and suggestions are welcome.

...well, it is a northern D - they call us often "Fischköpfe" because we love to eat fish here in Hamburg!
I just have summarized a bit the storage configuration I am thinking of
RAID Type
Objective
System requirements
RAID level
Offline Storage
store a whole video project (1h of 4k material requires about 128 GB)
needs to be highly reliable (redundancy is a must);
doesn't need to be extremely fast;
discs can be cheap because they don't have a high burden (just upload & download) to the video RAID.
10
Video RAID
store material for a day work
fast and reliable
10
Installation RAID
just to install Windows XP with CS4 Master Collection
redundant but speed isn't critical here
1
Working RAID
for page-file/scratch/renders
as fast as possible
disc failure isn't a big problem
0
In order to realize this, I am thinking of the following configuration
RAID Type
number of discs
Type
GB/disc
tot. storage [GB]
usable storage [GB]
cost [€]
Offline Storage
8
SATA
1500
6000
4800
900
Video RAID
6
SCSI/SAS
300
900
720
2100
Installation RAID
2
SCSI/SAS
36
36
30
200
Working RAID
4
SCSI/SAS
147
580
470
1000
Here are my assumptions and constraints:
I only have 6 bays for the Installation - and working RAID;
For the video RAID I also would like to reuse an enclosure, which just has 6 bays;
I would need to buy a NAS enclosure - so here I am open minded and just assumed 8 bays;
the usable storrage I estimated as 80% of the total storage;
discs, which are used heavily should be SCSI or SAS - I am thinking of the Cheetah 15K
Looking into the cost associated, I hit 4000€ easily just for discs. Ok, I can reuse some discs and enclosures, which I have here - but since I need to purchase the NAS enclosure (with 8 bays), which will also cost 1000€ additional, I will use 25% of my foreseen budget for storage.

Missing some basic functionality

I seem to be missing some basic functionality, like switching to tty1-n using Ctrl+Alt+F1-n. I can't begin to guess what this is related to, as after several installs I've never experienced that to be missing. Can anyone point me in the right directions? Thanks.

evr wrote:I was recently having problems with commands like because i was using "thinkpad" as the input.xkb.layout value in /etc/hal/fdi/policy/10-keymap.fdi. Changing to "us" helped me, perhaps that's the issue?
Hm. I don't actually have that file in the policy directory.

Some basic questions on File Adapter

Hello all,
I have some basic questions on XI and File Adapter and hope you can help me. Any answer is appreciated.
1. Can I use NFS transport protocol to poll a file from a machine in the network, which is not the XI? Or do I have to use FTP instead?
2. If I understand it correctly - when using the FTP-File Adapter, XI has the role of a ftp client. I have to run a ftp server on my distant machine. XI connects to FTP-Server and polls the file.
Can it also be configured the other way round? The scenario I think of would be: FTP client installed on distant machine, which connects to FTP-Server(XI) and loads up a file. So XI would act as FTP Server.
I know this works, if I install a ftp Server on the computer my XI runs on, and use the NFS-File Adapter to observe the folder. But I want to know, if I need a second, independant ftp server for this.
3. And last but not least: When do I need the active ftp mode instead of passive?
Thanx a lot for your answers!

XI cannot act as FTP server, but it is always a client. When XI is reading (File sender adpater) when XIis writing than it is File Receiver adapter

It depends on your firewall configuration. The best and the fastests is active mode but not always available.

Some basic queries on OAF

Hi All,
I have some basic queries in OAF...
1. What are the procedures to delete the Extensions?
2. After extending a VO, why we have to upload .jpx file and if we don't upload what will happen?
3. Can we use EO without altering the table to add WHO columns?
4. Why we have to develpe the OAF pages in webui and VOs in server folders only? is there any specific reason?
5. Are there any other methods to call the methods in AM apart from using am.invoke("<method name>") from CO?
Please give me the answers for these queries.....
Thanks in advance..
Srinivas

1. What are the procedures to delete the Extensions?
Go to "functional administrator" responsibility. Under personalization Tab click on Import/export. Search for your document and delete the customization.*
2. After extending a VO, why we have to upload .jpx file and if we don't upload what will happen?
You need to upload the jpx file because in your jpx file you have Substitute tag which substitute OLD VO with new VO and at runtime framework will check if there is any substitution available then It will substitute the old VO with the new one.*
3. Can we use EO without altering the table to add WHO columns?
I think no because when you perform DML operations on EO then framework tries to update the WHO columns and if WHO columns are not present you would get an error message*
4. Why we have to develpe the OAF pages in webui and VOs in server folders only? is there any specific reason?
There is no specific reason for this we can create our PG files in server folders as well and it would work fine. This is just a standard given by Oracle.*
5. Are there any other methods to call the methods in AM apart from using am.invoke("<method name>") from CO?
You should only use am.invoke .*

I'm new to using dbms_scheduler. I'm trying out some basic stuff to see how it works

I have not used the dbms_scheduler package before and trying out some basic functionality to see and understand how it works. The below code is what I have writtern
BEGIN
DBMS_SCHEDULER.create_job(
job_name => 'Test_Job3',
job_type => 'PLSQL_BLOCK',
job_action => 'BEGIN pr; END;',
start_date => systimestamp,
repeat_interval => 'freq=secondly;bysecond=4;',
end_date => null,
enabled => true,
comments => 'This job is test for dbms_scheduler'
END;
create procedure pr
is
begin
DBMS_OUTPUT.PUT_LINE('Inside the pr procedure called using scheduler');
end;
According to my understanding it should print the line inside the procedure 'pr' every 4 seconds, but I don't see any output being shown. Can someone help me understand what exaclty is wrong with my code. I'm using Toad for oracle.

One more question - I'm trying to bring in one more functionality. Lets says - There is a job that needs to be executed every month at a particular time. I schedule it, but I want this job to be executed 'n' number of times.
For example - There is procedure that is called in the scheduler. Since its processes lot of records - I'm breaking down in chunks of data - Say 5 chunks. Now when its scheduled each month at a particular time - it should ideally execute 5 times in order to complete the job for that month. How can this be achieved ? I thought of using max_runs, but that might end the job and never repeat it again.

Is the i7 13" Macbook Air capable of playing some basic games?

I'm looking into possibly grabbing a 13" Macbook Air with the i7 1.7Ghz processort and was wondering if it's capable of playing some basic games that are out in the Mac App Store such as Angry Birds, N.O.V.A. 2, or even Grand Theft Auto: San Andreas? Also I tend to use Vuze and sometimes Handbrake, would the high end 13" Macbbok Air be capable of doing all this for me?

Capable? Yes indeed it is. However, if the game or application is CPU or GPU intensive, then you can expect longer waits for completion of tasks. It's not so much noticeable on rudimentary games, but it really has an effect on detailed fluid motion in games that rely on such.
Handbrake tasks will just take longer to complete, it won't stop it.
I use my MBA's for medium intensity gaming without any complaints. But really, you should refer to the system requirements on each, on a case by case basis.

BW Basic Knowledge needed

Hello to all,
Can anyone in here give me the SAP Basic BW knowledge that I need to know to start supporting the said system?
In terms of issues encountered, I think for me is important to have knowledge is comparing data from R/3 and BW, how are data extracted, the jobs involved, the Info Packages needed, how do I track all these with BW Basic Knowledge?
Also, I need to check for results of BEx query Analyzer. Are these consistent with what is in R/3, what are the skills needed to support applications in BW for BEX.
Also, any suggestion on where do I need to start? Thanks.
Thanks to all who will respond.
