Some confusion in MDM

Hi,
I am new to MDM. I have some confusion with MDM:
1. After "Loading Master data" process data from MDC will be copy (except replicate) to MDS (Staging) or it just some logical links that will be stored in MDS towards MDC.
2. Before "Consolidating Master Data" process do we need to define some database schema over MDS or it is an automated process.
3. Apart from consolidation and harmonization within heterogeneous system landscape is there any other benefit associated with MDM 3.0?
4. Does MDM 3.0 shipment comes with MDC adaptor to connect with SAP (ERP and CRM) system and Non-SAP system (like people soft). To my understanding it does have adaptors for SAP but not for non-SAP system.
5. Help.sap.com say during initial load from trusted clients (ILTC) process ID mapping information can be loaded directly from the MDC and transferred to the CI. But how can we store ID mapping directly in MDC?
6. Do we need to have all these component in order to use MDM:
   a. Master Data Engine 3.0
   b. Content Integrator 3.0
   c. BI (BW 3.5)
   d. EP 6.0
   e. XI 3.0
   f.SAP Solution Manger 3.1
Thanks

Hello Raj,
answers foryour questions :
1. After "Loading Master data" process data from MDC will be copy (except replicate) to MDS (Staging) or it just some logical links that will be stored in MDS towards MDC.
A: The data will be copied, there are no logical links. After the extraction the data exist on the Client-system and in the staging area.
2. Before "Consolidating Master Data" process do we need to define some database schema over MDS or it is an automated process.
A: We have to consider different cases:
Case 1) Extraction of Standard object types like Business Partner: It's not necessary to define some Database schemas, for the MDM standard object types, they already exist.
Case 2) Extraction of Standard object types, but enhanced by additional fields, e.g BP has some extensions: These extensions need to be defined also on the MDM server, and a regeneration of the Staging are might be necessary. There are tools available to do this.
Case 3) If you would like to extract your own defined Object types, the object type needs to be defined on the MDM Server (with the Master Data Framework).
3. Apart from consolidation and harmonization within heterogeneous system landscape is there any other benefit associated with MDM 3.0?
A: To mention just a few: You keep your data in sync also in the future, Global Spend analysis can be done across systems, one stop Data Maintenance.
4. Does MDM 3.0 shipment comes with MDC adaptor to connect with SAP (ERP and CRM) system and Non-SAP system (like people soft). To my understanding it does have adaptors for SAP but not for non-SAP system.
A: For the available adapters please look in the MDM Master Guide. Adapters for third party systems are/can be provided by our partner community.
5. Help.sap.com say during initial load from trusted clients (ILTC) process ID mapping information can be loaded directly from the MDC and transferred to the CI. But how can we store ID mapping directly in MDC?
A: The ID mapping is not stored in the MDC, it's stored in the CI. The data is only extracted from the MDC's. Regarding key-mapping from an MDC perspective, there are no changes compared to the normal load.
6. Do we need to have all these component in order to use MDM:
a. Master Data Engine 3.0
b. Content Integrator 3.0
c. BI (BW 3.5)
d. EP 6.0
e. XI 3.0
f. SAP Solution Manger 3.1
You're right, with the exception of the SAP Solution Manager. Solution Manager is higly recommended in an MDM installation, but you can run MDM also without. Without e.g. customizing ID mapping would need to be done manually, which can be a major effort.

HT201365 I recently upgraded my Ipadto 'iOS7', I carried out all the instructions,added a 4 digit code and after some confusion understood all the upgrades.

I recently upgraded my Ipad to 'iOS 7' , after following the instructions and some confusion I added a 4 digit 'code' as requested. After getting used to all the new icons etc.the Ipad worked O.K.
Later in the day when I switched it back on I was asked to enter my 'code' - which I thought I had done, but by mistake I entered my 'password'. after tapping 'done' the message ' iPAD Disabled' appeared.

Some Confusion

I just started to work with Oracle, but I have some confusion about some things:
What is Oracle Database for?
What is Oracle Client for?
What is ODAC for?
I installed Oracle Database first, after that, I installed Oracle Client, till I installed Oracle client, Oracle database works Ok, but I installed Oracle Client and I couldn't get access to Oracle Database. Also I installed ODAC and the installation created other Oracle Instance...I'm really confusing with...
I appreciate some help

hi, welcome to forum !
Oracle database is used to store data of users in the form of tables which will be maintained using some physical and logical structures
Oracle client is a software which is used to access Oracle database, if it resides in remote machine
it is not necessary to install client if you want to gain knowledge on database
ODAC ic access components contains oracle client drivers helps applications to connect

Some confusion about 3D TV's and Syncing Glasses

There has been some confusion about our ad from last week and the offer to sync the 3D glasses with your TV.
We by no means intend to confuse our customers or offer fraudulent services. The offer is new to our stores, and our own employees have been in training just this week. Let me clarify the services included with the Samsung 3D TV offer that appears in this weekend’s insert. Geek Squad will:
Set up and connect your TV + up to 5 components.
Add internet connectable components to your existing wireless network.
Make sure your 3D glasses work.
Review and teach you how to use all of your new gear.
We have some customers who aren’t quite sure how the 3D glasses work, or that the glasses automatically sync with their new 3D TVs. So this informs them that they can depend on Geek Squad to answer their questions during installation and set-up. There is no additional charge for this – and the Geek Squad 3D installation and networking services are included in the total price of this offer.

Need some idea on MDM,BI

Hi Guys,
we are planning to develop application using BI and MDM .Currently we are focusing on sustainiability thing but want some more.
I just want you to share yr thoughts that help us developing more meaningful application .
Just share what basic problem you are facing or what you want to enhance or what new application you want on MDM and BI or any one of them.
Please share your ideas.
Thanks,
Sudhanshu

Hi markus,
Thanks for answering my queation.
Yes currently we are doing analysis on master data consolidation.
This is small idea.
We are trying to gather suggestion from the guys on community that what actually the problems they are facing and need solution on the problems above on MDM and BI or anyone.
Like we have a requirement give the supplier a application that accpet the data from supplier and before importing it to mdm first validate the whole file and then import it as there is no solution to first validate the the data provided by supplier that they are giving.
so we are working on this application also.
If you have any good idea that we can work on it then please share with us.
Thanks,
Sudhanshu

Some confusing issues and their solution while working with InCopy stories.

Hi All, Last few months I have been working on InDesign/InCopy workFlow.I faced lot many problems and able to find solutions for some of them.I am putting down some of the problems I haved faced and the approaches I followed to get the solutions. So here I go... First I will put the issues I faced and then their common solution. Issue 1)A text frame exported as a InCopy file. InterfacePtr<IDataLinkReference> dataLinkReference(frameUIDRef, UseDefaultIID()); if(dataLinkReference == nil) break; UID linkUID = dataLinkReference->GetUID(); If(linkUID == kInvlaidID) Break; The linkUID is always equal to kInvalidUID. Issue 2)A graphics frame with image placed inside it and exported as an InCopy file. In this case the linkUID will have a valid UID. So the code ahead is UIDRef linkRef(frameUIDRef.GetDataBase(), linkUID); InterfacePtr<IDataLink> dataLink(linkRef, UseDefaultIID()); if(dataLink != nil) { PMString linkedFilePath = *(dataLink->GetFullName()); } so here the linkedFilePath will be the file path of the linked incopy file and not of that image file. Issue 3)A graphics frame with image placed inside it but without any associated InCopy file. The linkedFilePath is that of filePath of an image. The solution I found was.. The reason for this confusing behaviour is, InCopy frame has one more UIDRef associated with the InCopy story. So to get the incopy related UIDRef we have to use the following code. UIDRef incopyStoryUIDRef = Utils<IInCopyWorkFlowUtils>()->GetContainingInCopyStory(itemUIDRef); The problem with above api is in case of the graphic frame the itemUIDRef should be the UIDRef of the frame and in case of text frame the itemUIDRef should be the UIDRef of the text story i.e the text model. To get the proper UIDRef use following code //code start UIDRef storyUIDRef(frameUIDRef.GetDataBase()); InterfacePtr<IPMUnknown> unknown(frameUIDRef,IID_IUNKNOWN); if(unknown == nil) { break; } UID textFrameUID = Utils<IFrameUtils>()->GetTextFrameUID(unknown); if(textFrameUID != kInvalidUID) { isTextFrame = kTrue; UIDRef textFrameUIDRef(frameUIDRef.GetDataBase(),textFrameUID); InterfacePtr<ITextFrame> textFrame(textFrameUIDRef,UseDefaultIID()); if(textFrame == nil) { break; } ITextModel * txtMdl = textFrame->QueryTextModel(); if(txtMdl == nil) { break; } storyUIDRef = GetUIDRef(txtMdl); result = Utils<IInCopyBridgeUtils>()->IsInCopyStory(storyUIDRef); } else { isTextFrame = kFalse; result = Utils<IInCopyWorkFlowUtils>()->IsInCopyStory(frameUIDRef); storyUIDRef = frameUIDRef; } //code end. Then use UIDRef incopyStoryUIDRef = Utils<IInCopyWorkFlowUtils>()->GetContainingInCopyStory(storyUIDRef ); Once you have the proper incopyStoryUIDRef, the following code works uniformely and you will always get the incopy file irrespective of the type of frame. IDataLink * dLink = Utils<IInCopyBridgeUtils>()->QueryDataLink(incopyStoryUIDRef); if(dLink == nil) { break; } so dLink->GetFullName() will always give you the incopy file path associated with the frame. Hope this helps somebody working on InCopy stories. But I still could not find the way to find the image file path associated with the graphic incopy story.(refer issue 2 above.).Using above approach I always get the file path of associated incopy file. I will keep this thread updated as and when I encounter with some more issues and find their solutions. Thanks and Regards, Yopangjo.

I cannot explain why your iMac worked ok. I too have seen situations where "lower cost" WiFi routers like Belkin and LInksys have "sort of" worked but had problems.
Back in 2004 after buying a fairly large house I purchased an off-brand WiFi gateway that featured high power output so I could mount it centrally in the house and be able to use WiFi everywhere. Even though this thing was rated well and had the high-power everyone said would help it gave me continuous problems.
One day a buddy gave me an Apple Airport (the one that looks like a apple power adapter). I plugged it in where I had the high power unit in place and suddenly I had amazing WiFi speed and coverage EVERYWHERE. I could not believe it! That day I ordered an Airport Extreme and it has been fantastic.
I then recommended this solution to a friend of mine that had an Apple MacBook and he had nothing but trouble and went back to his linksys. So it is a mixed bag.
Currently I have three WiFi devices: A TimeCapsule downstairs, an Airport Extreme upstairs and a LInkSys in a utility closet. The LinkSys is needed because my son's GF's Windows computer will not connect to anything else.
Anyway glad you figured something out.

How does oracle execute a correlated subquery .... some confusion

How does oracle 10g execute a correlated subquery?
I read some articles online & i am a little confused.
example:
select * from emp e
where e.deptno in (select d.deptno from dept d
where e.deptno = d.deptno);
My questions .......
1.In the above example, does oracle read the entire outer table first and then run the inner query using the rows returned by the outer query?
I read in some articles that they execute simultaneously.
How does this work?
2.Should the inner query have lesser amount of rows compared to the outer query for a good performance?
3.Can every correlated subquery be converted to a join and if so which one to use?
Truly appreciate any inputs on how oracle executes it at the backend.
Thanks in advance.

How does this work?SQL is not a procedural language. SQL code specifies what the system sill do, not how the system wlll do it; that's entirely up to the system.
What does it matter to you whether the two are done together, or if one is completed before the other begins?
The system will probably choose to run ucorellated subqueiris only once, and correlated queries multiple times as needed.
2.Should the inner query have lesser amount of rows compared to the outer query for a good performance?That usually doesn't matter.
It some cases, you may want to consider whether the subquery is correlated or not. If the subquery is very costly, and produces, say, 1 million rows, but you know the main query will only produce about 5 rows, then you may want to do a correlated subquery rather than an uncorrelated one.
3.Can every correlated subquery be converted to a join and if so which one to use?I believe so.
Use whichever is easier to code and debug. That will change depnding on the data and the requirements.
If performance is an issue, try different ways. Usually, where I've noticed a big difference, join was fastest.
By the way, it's unusual to have a correlated IN-subquery.
Usually IN-subqueris are uncorrelated, like this:
select *
from      emp     e
where     e.deptno     in ( select d.deptno
                    from    dept     d
                  );(This and the queries below produce the same resutls as your original query.)
Correlated subqueries are usually used for scalar subqueries or EXISTS subqueries, like this:
select *
from      emp     e
where     EXISTS ( select d.deptno
           from    dept     d
                where   e.deptno = d.deptno
            );To do the same thing with a join:
select e.*
from      emp     e
join     dept     d     on     e.deptno     = d.deptno
;assuming dept.deptno is unique.

Some question about mdm java api and portal content

Hi Gurus,
I am new to MDM. I am going to develop some web dynpro application using mdm java api.
My question is regarding the relationship between MDM version and NW version:
for example
1.MDM5.5 JAVA api can be deployed to CE 7.11 server?
2.MDM7.1 JAVA API can be deployed to CE 7.11 server? or can only be deployed to CE server.
the same question for the MDM portal content.
the possible dev environment for our company would be:
1.MDM7.1
2.CE7.2(do we need another EP7 server for the UWL?)
Best regards,
John

Hi,
I am using Portal 7.0. MDM version is 7.1.
My problem is ... i am trying to connect WebDynpro (JAVA) to MDM7.1. But am unable to do so. I have a WD Frame in which i have a WD iView and the MDM iView. But i am unable to pass parameters from the WD iView to MDM Item Details iView.
Note:
1. I have deployed MDM JAVA API on NWDS
2. I have specified " * " as a parameter to pass from the URL in the Item Details iView.
Please help.
Every help that i have read talks about CE7.1 but not NW 7.0

Queues, Priority and SLOs - Some confusion

Hello all,
Please bear with me on this one, I'm currently trying to get my head around Queues and SLOs with regards to priority. My existing helpdesk software uses a lot of odd terms to describe all these items so I'm having some trouble while setting up SCSM
2012.
Some background; we don't use tiers of helpdesk but rather departments (Desktop, server, infrastructure etc) so any job comes along unassigned and anyone can pick it up and assign it to the correct department.
The question I have is that if I set a incident's priority using the urgency and impact, do I need to do an SLO for each level (1-9) of the priority and set a target and warning threshold for each?
Cheers

You will have to ask yourself some questions first.
Do you want to use all 9 priorities?
Do you want to apply an SLO to all (9) priorities? Do you really have a SLA agreement that applies to all possible incidents (and/or service requests)?
Normally you would only apply an SLO for the most critical incidents, or incidents or other requests you have a standard solution time for (like something that is (semi)-automatic.
Do you want to apply a SLO to all types of incidents (again look at available SLA agreements)
Lastly there is not much point in having SLOs if they are not respected
You can have different entry-points on the service manager portal that allows you to automatically route the request to the proper team/department/support group/whatever.

Some confusion about files on the hard drive and those in LR

i have been importing files directly into LR and at the same time creating a folder in My Pictures where the original files are stored. i then edit in LR.
in order to save and then backup up edited files i export them to another folder marked "fotos 2010 LR", the first folder being "fotos2010'.
my confusion is having both folders. i know that if i delete the original folder it will also delete those corresponding files in LR.
reading this over now i suppose i could export to "fotos2010" folder and write over original files but im afraid to do that. is that a good idea?
am i doing something wrong? i feel like i'm missing something about LR works.
thanks
harvey

The best way forwards rather depends on how far you have gone with your 'new' catalog.
On the one hand you have an 'old' catalog that contains your edits and your collections, but because you moved the original files and folders outwith LR the catalog, and it's record of the files it knows bout, is 'disconnected' from the source files.
On the other you have a 'new' catalog that knows where all the pictures are but doesn't have your changes and collections.
If you haven't done much work with the new catalog you might be better to open the original catalog and update it with the location of files it has lost sight of. In library mode right click a directory showing errors and select 'Update folder location'. Depending on the scale of your mix up this might be quite time consuming, proceed slow and sure and all will be OK in the end. What you won't have after this is any work you've done in the new catalog.
If you've done a lot of work in the new catalog then you are better off staying with it and trying to recover work from the old catalog. You'd have to do the updating of links discussed above first but having done so you can then write the changes made by LR out to the original pciture files. The 'picture' doesn't change but the file now has a list of changes applied by LR stored in a manner that can be interpreted by LR and other programs (technically not within the file itself but an associated side-car file). With the old catalog open select 'Save metadata to File', with the appropriate pictures selected. Once the data has been written out you can open the new catalog and 'Read Metadata from Files' to get the new catalog to be aware of the changes held within the picture file. That won't recover your collections however, I think you're stuck there. I don't know of a way to 'export' a collection and 'import' it into a new catalog. Given that a collection is essentially a list of picture files that LR knows about I can't really see how it would be possible given that the original problem is that the old and new catalogs have a different idea of where the original source photo files are.
My gut feel - Unless the help here has made you pretty confident I'd stick with the new catalog, take the hit and recreate the collections from scratch.
Cheers

Still some confusion on Icons in Application Folder

I installed Firefox & Thunderbird on my iMac. I like Firefox, but not T'Bird.
In the application folder, I have 2 Icons for Firefox - one looks like a computer drive, and the other is the same circle as I have in my dock. I have only one Icon for T'Bird - that being the one that looks like a computer drive. I also have both of these drive-like Icons on my desktop.
When I startup the computer, T'Bird is never on the dock. Firefox is. When I doubleclick on the drive-like Icon in the applications folder it opens a window under MacIntosh HD which if I then double click on, T'Bird opens. If I do the same with Firefox, firefox opens.
Which of these Icons should be in the Appl folder/ On the desktop? Do I get rid of some/ All?
Thanks.

When you downloaded Firefox and T'Bird you got these guys that "look like a computer drive. They are 'Disk Images' and they are virtual computer drives. SO, double click on on, and there it is, under the Macintosh HD, just like a Drive.
To install the software, drag it from the Disk Image to the Applications Folder. You've done this with Firefox, but haven't with T'Bird. Then eject the DIsk Images and trash them. Thn in your Applications folder you have theround icons for the apps themselves, and not the icons for the disk images.
