EHP5: What are prerequisites relative to ERP/EHP, & NW support packs

We understand that ERP EHP5 is going into Ramp Up in December, 2010. To add EHP5 to our environment, what are the minimum support pack levels for ERP (we are currently under EHP4 support pack 4, moving to 7), as well as any other support pack level dependencies for NetWeaver? (In other words, what are the "jumping off points" from previous support pack levels?)
Any estimate of General Availability for EHP5?

Hello,
Based ón the current support pack level EHP5 stack will be generated with pre requisites .
You have to maintain the data in solution manager.
EHP Installer will take care rest of the things like notes tobe implemented , SAINT/SPAM versions.

What are the Relations between Journalizing and IKM?

What is the best method to use in the following scenario:
I have about 20 source tables with large amount of data.
I need to create interfaces that join the source tables into target tables.
The source tables are inserted every few secondes with about hundreds to thousands rows.
There can be a gap of few seconds between the insert of different tables that sould be joined.
The source and target tables are on the same Oracle instance and schema.
I want to understand the role of: 'Journalizing CDC' and 'IKM - Incremental Update' and
how can i use it in my scenario?
In general What are the relations between 'Journalizing' and 'IKM'?
Should i use both of them? Or maybe it is better to deelte and insert to the target tables?
I want to understand what is the role of 'Journalizing CDC'?
Can 'IKM - Incremental Update' work without 'Journalizing'?
Does 'Journalizing' need to have PK on the tables?
What should i do if i can't put PK (there can be multiple identical rows)?
Thanks in advance Yael

Hi Yael,
I will try and answer as many of your points as I can in one post :-)
Journalizing is way of tracking only changed data in your source system, if your source tables had a date_modified you could always use this as a filter when scanning for changes rather than CDC, Log based CDC (Asynchronous in ODI, Logminer/Streams or Goldengate for example) removes the overhead of of placing a trigger on the source table to track changes but be aware that it doesnt fully remove the need to scan the source tables, in answer to you question about Primary keys, Oracle CDC with ODI will create an unconditional log group on the columns that you have defined in ODI as your PK, the PK columns are tracked by the database and presented in a Journal table (J$<source_table_name>) this Journal table is joined back to source table via a journalizing view (JV$<source_table_name>) to get the rest of the row (ie none PK columns) - So be aware that when ODI comes around to get all data in the Journalizing view (ie Inserts, Updates and Deletes) the source database performs a join back to the source table. You can negate this by specifying ALL source table columns in your PK in ODI - This forces all columns into the unconditional log group, the journal table etc. - You will need to tweak the JKM to then change the syntax sent to the database when starting the journal - I have done this in the past, using a flexfield in the datastore to toggle 'Full Column' / 'Primary Key Cols' to go into the JKM set up (there are a few Ebusiness suite tables with no primary key so we had to do this) - The only problem with this approach is that with no PK , you need to make sure you only get the 'last' update and in the right order to apply to your target tables, without so , you might process the update before the insert for example, and be out of sync.
So JKM's provide a mechanism for 'Change data only' to be provided to ODI, if you want to handle deletes in your source table CDC is usefull (otherwise you dont capture the delete with a normal LKM / IKM set up)
IKM Incremental update can be used with or without JKM's, its for integrating data into your target table, typically it will do a NOT EXISTS or a Minus when loading the integration table (I$<target_table_name>) to ensure you only get 'Changed' rows on the load into the target.

I want to understand the role of: 'Journalizing CDC' and 'IKM - Incremental Update' and
how can i use it in my scenario?Hopefully I have explained it above, its the type of thing you really need to play around with, and throroughly review the operator logs to see what is actually going on (I think this is a very good guide to setting it up : http://soainfrastructure.blogspot.ie/2009/02/setting-up-oracle-data-integrator-odi.html)
In general What are the relations between 'Journalizing' and 'IKM'?JKM simply presents (only) changed data to ODI, it removes the need for you to decide 'how' to get the updates and removes the need for costly scans on the source table (full source to target table comparisons, scanning for updates based on last update date etc)
Should i use both of them? Or maybe it is better to deelte and insert to the target tables?Delete and insert into target is fine , but ask yourself how do you identify which rows to process, inserts and updates are generally OK , to spot a delete you need to compare the table in full, target table minus source table = deleted rows , do you want to copy the whole source table every time to perform this ? Are they in the same database ?
I want to understand what is the role of 'Journalizing CDC'?Its the ODI mechanism for configuring, starting, stopping the change data capture process in the source systems , there are different KM's for seperate technologies and a few to choose for Oracle (Triggers (Synchronous), Streams / Logminer (Asynchronous), Goldengate etc)
Can 'IKM - Incremental Update' work without 'Journalizing'?Yes of course, Without CDC your process would look something like :
Source target ----< LKM >---- Collection table (C$) ----<IKM>---- Integration table (I$) -----< IKM >---- Target table
With CDC your process looks like :
Source Journal (J$ table with JV$ view) ----< LKM >---- Collection table (C$) ----<IKM>---- Integration table (I$) -----< IKM >---- Target table
as you can see its the same process after the source table (there is an option in the interface to enable the J$ source , the IKM step changes with CDC as you can use 'Synchronise Journal Deletes'
Does 'Journalizing' need to have PK on the tables?Yes - at least a logical PK in the datastore, see my reply at the top for reasons why (Log Groups, joining back the J$ table to the source table etc)
What should i do if i can't put PK (there can be multiple identical rows)? Either talk to the source system people about adding one, or be prepared to change the JKM (and maybe LKM, IKM's) , you can try putting all columns in the PK in ODI. Ask yourself this , if you have 10 identical rows in your source and target tables, and one row gets updated - how can you identify which row in the target table to update ?
>
Thanks in advance YaelA lot to take in, as I advised I would reccomend you get a little test area set up and also read the Oracle database documentation on CDC as it covers a lot of the theory that ODI is simply implementing.
Hope this helps!

What are the relation between JPA and Hibernate, JPA and TopLink?

What are the relation between JPA and Hibernate, JPA and TopLink?
Can JPA instead of Hibernate and TopLink?

The Java Persistence API (JPA) is the object relational mapping persistence
standard for Java. Hibernate and TopLink provide an Open source Object-relational mapping framework for Java.
They provide an implementation for the Java Persistence API. In my opinion, both Hibernate and TopLink provide support to JPA
and they can also be regarded as the complementary to JPA.
Let's wait to see other person's opinions.

What are the common errors we get in supporting project

can any body reply what are the common errors we get in supporting project
for abapers tickets will get or not.
what type of tickets generally get regarding reports.

SAP Tickets are nothing but problems or issues raised by the end
customer in a company where end users are running SAP project.
Once the SAP project is implemented, support phase begins. Support
team is responsible for solving the tickets/issues in day-to-day
business.
For any support project, customer will set up Help Desk. If any
problem occurs customer will call Help Desk and register the
issue/Ticket.
Different companies use different software products to manage SAP
Tickets. Remember this software is not provided by SAP. It is third
party software. There are many software products in the market like
Manage Now et c. You can call these software products as tools.
All tools will provide the common attributes which are listed below-
1) Every user will be provided with user name and password to enter
into the tool
2) We can see the tickets assigned for a particular user name.
3) You can list all open tickets by giving the Date Range
4) You can list all closed tickets by giving the Date Range
5) You can list out all the open tickets assigned for an User
6) You can list out all the closed tickets assigned for an User
7) You can see the description of the Ticket, by entering the Ticket
Number. You can see who had raised the Ticket, what is the problem.
What is the severity of the Ticket?
There are lot many other attributes like you can transfer the Ticket
to another user etc.
What is the severity of the problem Ticket?
When a Ticket is raised, it will be given severity. There are
following severities. It may vary from company to company.
Severity 1
Severity 2
Severity 3
Severity 4
The severity will be decided based on the business critical impacts.
If there is large impact on the business it
will be given 1 severity, if it is having least impact then it will be given 4.
Severity 1 problem tickets should be solved in 8 hours.
Severity 2 problem ticket should be solved in 16 hours.
Severity 3 problem ticket should be solved in 15 working days.
Severity 4 problem ticket should be solved in 30 working days.
Again the no of days may vary from one company to another.
All these things will be decided when giving the contract to the IT
company. The agreement is called as "SLA".
SLA stands for Service Level Agreement.
What happens if a particular ticket is not solved by the IT company
according to the SLA/Contract?
The Customer imposes fine on IT company as per the contract/SLA.

2) Invalid characters while loading.
3) ALEREMOTE user is locked.
4) Lower case letters not allowed.

6) object locked.
7) "Non-updated Idocs found in Source System".
8) While loading master data, one of the datapackage has a red light

3) repeat of last delta not possible
4) datasource not replicated
5) datasource/transfer structure not active
Issues faced during the implementation :
1. Slippage of milestones
2. Incorrect or wrong design
3. Reporting format problems
4. Data not matching or reconciling problems
5. Issues discovered during testing leading to redesign
6. Performance issues
7. Requirements misinterpretation
9)check the data same in source system and target system ( i mean
suppose u are extarcting from r/3 after loading check ur data r/3 and
bw same or not.
10)that is abap code, i didnt understand ur question properly.
11)
12) generic extarction, if ur businees contect satisfy ur requirement
u go for generic, suppose u need data from different tables go generic
with view with 1:1 relation 1:M relation for function module.
13)v3 update back groud job is in lo
14)its superior info object, u can find this in master data tab .
15)
16)tuning we will go for improve query performance (compression,
aggregates, partation, index, rollup, precalculated web tneplates.)
17) rsa7(check with some one)
18)bw statics for find data base time and olap time and frontend
time(based on u can improve query performance create like aggra comp ,
indices etc..)
19) direct chain only one chain , meta chain if u have more than one chains
load errors u can solve manually, other than load errors u can wait
right click and repeat.
20)
21) u cn cteate other cube and traansfer, but data space waste.(bec
structures will be deffi)
22) u mean data source enhancement.or not(let me know)
23)rsap0001( for customer exit variables) 001 for transaction data 001
attributes, 003 text 004 hierchies.
24)web application design , its like same bex, but report will execute
in browser.
25)
26) arrangement of process are called process type and we can use
varient and start process for back ground jobs.

What are the sap basis daily activities in support project

Hi Friends, recently i am involved in Support project, could you please tell me what are the daily activities to follow in support project
thanks&regards
suresh

Hi Suresh,
Few of daily activities in which you as a Basis Consultant should involve are as below:
- Day to day system administrative issues raised by users e.g. User ID locked or new SAP ID creations etc.
- Daily watch on background batch jobs. If any job failed due to some reason, work on it to avoid such failure in future with the help of function consultant
- Watch on system performance
- Authorizations & Roles definitions & assignements depending upon requirement.
- System Backup depending upon business requirement
- Printer setup in SAP
- Watch on Print spool to avoid failures in SAP doccuments printing
- Watch on interfaces (IDoc/EDI etc), if any, with external system
Also talk to your earlier or senior Basis consultant to know more.
Hope it will help you.
Regards,
Anup

HT5219 What are the external monitor requirements that can support having two windows email and safari open side by side?

I have a 27" iMac at home that supports this but would like to see if I can enable my Macbook air to do the same thing. I want to find out if this capability can be supported with my Macbook air and if so what are the monitor requirements.

Usually two causes of that, the first being the windows dpi scaling (most common cause) and the second being your graphics card driver needs to be updated.
Try playing with the windows dpi settings
Right click on your Desktop and select Screen Resolution
Then in the screen that comes up, click on Make Text or Other Items Larger or Smaller
Then move the slider under Change the Size of All Items to Smaller and restart windows 8
Also, you can try clicking on Let me choose one scaling level for all my displays, then click on Custom sizing options and drag on the rulers to set 149% and see if that is any better.

Hi Graham,
I think you got me wrong. The change was made after SP9, I am asking which support pack this change was introduced in?
We have ERP 6.0 with SP9 and this change is NOT there. We also have ERP 6.0 EHP 4 and the change IS there. The code snippet I posted is from ERP 6 EHP4.

Objects are locked in open change requests during support packs update

Hi All,
We are applying support packs in the ECC Dev system. Its giving error in phase OBJECTS LOCKED..? after that i checked with ABAP consultant he given requests which i unlocked the objects from SE03. Still the same error Objects are locked in open change requests is coming.
If i checked requests which are not released, those are in hundreds which we can not release. How can i find a specific object which i need to unlock or any chance to skip the phase and continue. Because 15 days back i have updated the support packs without any of the issue.
Please suggest me whether i can find the specific objects to unlock or any other process.
Thanks & Regards,
Sreekanth

Hello,
Normally when we double click on that error message 'objects are locked', system takes us to the transport requests containing those objects in question.
And did you try SE03 --> Objects in Requests --> Search for Objects in Requests/Tasks ?
Thanks

What are the relations?

Could anyone please brief me what the relations are among those products under the BI category?
http://www.oracle.com/technology/tech/bi/index.html
AWM, OLAP, DataWarehouse, Data Mining, Real-Time Desicion, BI Publisher, etc.
Thanks!

AWM - Analytic Workspace cubes, used to build OLAP cubes in an Oracle database, create OLAP DML applications etc
OLAP - Industry term, also refers to the Oracle OLAP Option
DataWarehouse - a database which is generally optimized for extracting data, as opposed to inserting data - Google for more info, Oracle supplies exadata 'datawarehouse machine' which is a hardware / database platform ideal for large datawarehouse / data throughput etc.
Data Mining - An oracle product, which allows you to perform data mining !! I dont know much about it, I'd google it for more.
Real-Time Desicion - I think this was a Siebel CRM add-in, not quite sure.
BI Publisher - Formerley XMLPublisher, supercedes Oracle reports, very good for 'pixel' pefect reporting & bursting, can be embedded within OBIEE, Apex etc. can use pretty much any datasource you can connect to with JDBC, also uses BI Server as a data source
so Datawarehouse (read oracle db enterprise edition) , OLAP are products for storing data (Oracle Warehouse builder is an ETL tool for loading these products)
Data Mining, OBIEE, RTD (Real Time Descisions), BI Publisher are all query tools, ie extracting data from your marvellous datawarehouse ! (or other sources)
Hope this helps

What are the hours of operation for phone support? I cannot find them and the phone system just says between regular hours?

My patience has been pushed to its limit with this iPod and I cannot find hours of operation for customer service and tech support and the phone system just tells you no one is available and call back during regular hours, but nothing saying what those hours are. Does anyone know?

Looking at the Apple's website and previous posts, Apple does not publish the hours. Did you can in the USA during the times that corresponsd to about 9AM to 4PM Pacific time?
