What is MDM in BI and ERM????

Hi Gurus,
I am new to Nterweaver BI can any one help hoe to make a start with BI and can any one answer What is MDM in BI and ERM????
Regards
Madhavi

Hi Madhavi,
I guess from BI perspective MDM is Multi Dimension Modelling and ERM is Entity Relationship Model. They are both used for Data modeling in BI.
Check this PDF document on modeling:

MDM 7.1 and PI 7.1 scenarios

Hay ..
PI 7.1 is having an adapter itself for Fetching Data from MDM Server.
What PI/ XI MDM Adapter will do is , it will keep on checking the MDM ready folders for Data.
you will create a MDM repository and PORT on MDM Server .. and provide this to Your XI / PI Guy ...
He/she will use this Repository and Port into config of there MDM Sender Adapter .. and MDM adapter will generated XML file from here..
and Vice versa.

Keep RAR and ERM up to date with Z transactions

Hi all,
As you all know, Z transactions are added on the ongoing dayly basis to a SAP system.
My question here:
What is the best practice to keep RAR and ERM up to date in terms of this information?
Many thanks in advance. Kind regards,
Imanol

Raghu,
What I meant is the best practice to make such Z transactions available in RAR and ERM database to be available to define new functions and / or define new roles.
Should periodic upload for action-permission file need to be executed in RAR?
AND
action, object job syncronized in ERM?
Hope this clarifies my question.
Thanks for all. Kind regards,
Imanol

MDM 3.0 and MDM 5.5

Hi All,
Can any body tell what are the differences between MDM 3.0 and MDM 5.5?
Regards,
Nikhil

MDM 3.0
Strengths
Supply chain expertise
Global metadata synchronization expertise  especially important to Consumer Packaged
Goods and Retail industries
3rd generation hub architecture with near term 4th generation features (image/content
management of A2i)
Weaknesses
Few production references
Early ramp up sites included: Deutsche Telekom, Dorel/PacificCycle, ENEL, General
Electric Consumer and Industrial, Heineken, Kingfisher Group, Nestlé, Nokia, Pemex,
Purdue University, Rubbermaid, Shell Europe, Tesoro Petroleum, Weyerhauser,
Whirlpool
Can be purchased only on approval of SAP executive management on case by case
basis
Batch emphasis; on-line capability not suitable for high transaction rates in large-scale
B2B or B2C scenarios
Emphasis on product/supplier capabilities rather than customer/employee
Lack of strong SI channel (the number of SIs promoting NetWeaver is a good channel,
however, the subset that are catering to SAP MDM is far smaller)
Under invested in marketing
No longer supported after 2012
MDM 5.5
Strengths
Support for single view of all major objects  customer, product, supplier and employee
(albeit lightweight customer and employee)
Focused on interactive cleansing and distribution of Material, Supplier, Customer, and
Employee master data within (SAP R/3-based) ERP environment; note that several large
organizations are using it outside of a SAP ERP environment such as GE and
Rubbermaid
Global metadata synchronization expertise
Product information management focus
o Fully integrated electronic and print publishing
o High performance parametric search across rich content
Hierarchical management
Integration with SAP infrastructure
4th generation data hub features (image/content management of A2i)
English, French and German initial support; Japanese 3Q2005
Weaknesses
Minimal references (Whirlpool)
Currently only supports master data harmonization  no automated central authority for
master data and therefore cannot enforce centralized/corporate data quality standards
Focused on interactive cleansing and distribution of Material, Supplier, Customer, and
Employee master data within (SAP R/3 based) ERP environment (n.b. = Not a typo  this
is either a strength or a weakness depending upon ones requirements)
Batch emphasis, e.g. customer data is typically replicated in batch mode among
participating systems; however, enterprises can propagate customer data using the same
common architecture that is used by the product hub for replication/distribution via SAP
NetWeaver Exchange Infrastructure or directly via APIs
Lack of strong SI channel (the number of SIs promoting NetWeaver is a good channel,
however, the subset that are catering to SAP MDM is far smaller)
Under invested in marketing (if SAP was true believer at the executive level in the
strategic nature of enterprise master data management, then the SAP MDM product
would be much more prevalent in the overall SAP marketing mix)
Emphasis on product/supplier capabilities rather than customer/employee
Hope this will be helpful.
Reward points if found useful.

Differences between MDM 3.0 and MDM 5.5?

Hi,
Can anybody tell, what are the differences between MDM 3.0 and MDM 5.5?
I heard that, there are lot and lot of changes...
Thanks for your reply,
regrads,
cg

We can look at differences in more than one way:
1. Technology wise
MDM5.5 is developed in C++ & runs on a C++ engine as compared to MDM 3.0 which runs under WAS
However MDM 5.5 is integrated with NW largely, though it can & is planned to be improved further
2. Product Catalog Management
MDM 5.5 has rich PCM capabilities which did not exist in MDM 3.0
3. Other additional capabilities in 5.5
Multilingual support
Syndication of data to XI or file system
Lean, R/3 Idoc based model for supplier, customer, material, employee
4. Ease of installation and usage is a also an advantage of 5.5
You can read Nitza Levi's blog on MDM home page for more details

What is MDM Work Flow

Hi MDM frnds,
What is MDM work flow, its Just like ABAP Work Flow??
At what stage we need to define MDM work Flow??
If anybody having usefull documentation shere to me..
Regards,Raj

Hi,
What is MDM work flow?
Workflow is used to run the processes working on master data in a systematic and orderly way.
Generally, we need to have some validations and approvals in order to make sure that master data is
correct.These validations ,approvals and other processes are not done by the single person.Different
operations will be done by different users in master data management.In order to control the overall
processes done by different users in an systematic way, we need workflow.
At what stage we need to define MDM work Flow??
As i said above whenever we have validations, assignments and matching and merging and various
approvals which should be act on our master data before send the master data various application
Systems, then we go for workflow.
For example as soon as we import the data, workflow can be triggered by setting configuration options
in import manager and imported records can be addeed to workflow automatically by setting Trigger action
to record import.By doing this,we can cleanse and normalize the data using various operations in workflow.
and also we can execute the MDM workflows in portal using guided procedures.
Not only that using workflow we can extract the data from MDM to remote system using syndicate step(Available from SP5) of the workflow.
Finally what i can say is using workflow all the operations which need to be executed on master data can
be done in a proper way.
For better understanding, go through below documnents.

MDM web services and the MDM BP services

Hi *,
I need to know what is the difference between the standard MDM web services and the MDM BP services. How do I decide which set to use?
- Kris

Sorry but what are BP services? Do you mean Business package?
If yes the approaches are completely different - you use Web Services when you have to customise the application and build your logic/functionality into the app. CRUD operations are procided by Web Services - you need to form your wrapper application from scratch and develop!
With BP - it involves least development effort bearing in mind that its all standard content and not yet completely customizable. So based on your requirements plan whether to go for Business Package or Web Services or Java API completely...

I've just found that three movies I've bought from iTunes on on my iPad are not showing up on Apple TV or anywhere other than that iPad. What's up with that and will I lose these films if I reset this iPad?

I've just found that three movies I've bought from iTunes on on my iPad are not showing up on Apple TV or anywhere other than that iPad. What's up with that and will I lose these films if I reset this iPad?

Thanks. The reason this has become an issue is that I recently bought a new Macbook Air that the iPad is not synced to. The one is was synced to was stolen. If I want to sync this iPad to the new Air, won't it be wiped before I'm able to copy these films or am I wrong about that?

FAQ: What features use the GPU and how do I troubleshoot GPU issues?

Photoshop CS6 GPU FAQ
Introduction
This document provides a quick reference guide to video card usage in Photoshop. Some features require a compatible video card to work; if the video card or its driver is defective or unsupported, those features will not work at all. Other features use the video card for acceleration and if the card or driver is defective those features will run more slowly.
Mercury Graphics Engine
The Mercury Graphics Engine (MGE) represents features that use video card, or GPU, acceleration. In Photoshop CS6, this new engine delivers near-instant results when editing with key tools such as Liquify, Warp, Lighting Effects and the Oil Paint filter. The new MGE delivers unprecedented responsiveness for a fluid feel as you work.
MGE is new to Photoshop CS6, and uses both the OpenGL and OpenCL frameworks. It does not use the proprietary CUDA framework from nVidia.
In order to use MGE, you must have a supported video card and updated driver. If you do not have a supported card, performance will be degraded. In most cases the acceleration is lost and the feature runs in the normal CPU mode. However, there are some features that will not work without a supported video card.
GPU features added in Photoshop CS6
Adaptive Wide Angle Filter (compatible video card required)
Liquify (accelerated by compatible video card with 512MB VRAM, GPU mode unavailable on Windows XP)
Oil Paint (compatible video card required)
Warp and Puppet Warp (accelerated by compatible video card, GPU mode unavailable on Windows XP)
Field Blur, Iris Blur, and Tilt/Shift (accelerated by compatible video
card supporting OpenCL, GPU mode unavailable on Windows XP)
Lighting Effects Gallery (compatible video card required with 512MB
VRAM, unavailable on Windows XP)
New 3D enhancements (3D features in Photoshop require a compatible video card with 512MB VRAM, unavailable on Windows XP):
Draggable Shadows
Ground plane reflections
Roughness
On-canvas UI controls
Ground plane
Liqht widgets on edge of canvas
IBL (image based light) controller
* Note that all 3D features are unavailable on Windows XP in Photoshop CS6
GPU features added in previous versions of Photoshop
Scrubby Zoom. See Zoom continuously
Heads Up Display (HUD) color picker. See Choose a color while painting
Color sampling ring. Choose colors with the Eyedropper tool
Brush dynamic resize and hardness control. See Resize or change hardness of cursors by dragging

Full-screen preview
Review mode
See Preview and compare images in Adobe Bridge CS6 Help for information on all of these features.
GPU/OpenGL preferences in Photoshop CS6
The advantages of using a compatible video card (GPU) with Photoshop are that you can experience better performance and more features. Problems can occur if you have an older video card with limited VRAM or if you use other programs at the same time as Photoshop that use the GPU.
Choose Edit > Preferences (Windows) or Photoshop > Preferences (Mac OS).
In the Performance panel, make sure Use Graphics Processor is selected in GPU Settings.
Click Advanced Settings and specify the following options:
Mode > Basic
Mode > Normal
Mode > Advanced Provides the benefits of Normal mode as well as newer OpenGL advances that can result in improved performance.
Use Graphics Processor to Accelerate Computation
Use OpenCL Uses the GPU to accelerate the new blur filters (Field Blur, Iris Blur, and Tilt-Shift) – OpenCL will only be available on newer GPUs that support OpenCL v1.1 or higher
Anti-Alias Guides And Paths Allows the GPU hardware to smooth the edges of drawn guides and paths.
30 Bit Display (Windows only) Allows Photoshop to display 30 bit data directly to screen on video cards that support it
Quick GPU Troubleshooting Steps
You can experience problems such as artifacts, errors, and crashes if there are incompatibilities between Photoshop and the display components that access the GPU.
If you experience crashes, incorrectly rendered windows or objects, redraw issues, or performance issues while running Photoshop, first determine whether OpenGL is causing the problem.
Turn off OpenGL.
Choose Edit > Preferences (Windows) or Photoshop > Preferences (Mac OS).
In the Performance panel, uncheck Use Graphics Processor. Click OK.
Restart Photoshop, and perform the same function.
If the problem recurs while OpenGL Drawing is disabled, OpenGL is not the cause. For additional troubleshooting, see Troubleshoot system errors and freezes | Adobe software on Windows (cpsid_82252) or Troubleshoot system errors and freezes | Adobe software on Mac OS 10.x (cpsid_82414).
If the problem resolves, proceed with the rest of the troubleshooting steps to fix OpenGL.
Make sure that you're using the latest update of Photoshop.Updates fix bugs and issues.
Update the display driver.Updated display drivers can fix many issues, such as crashing, incorrectly rendered objects, and performance problems. Determine what video card you have and go directly to the manufacturer's website (nVidia or ATI/AMD) and download the latest driver. (Note: Simply doing a Windows Update is does not guarantee you are using the latest driver. You must go directly to the nVideo or ATI/AMD websites to get the absolute latest driver.) After you update your driver, turn on Use Graphics Processor in Photoshop preferences.
Reset preferences.
Resetting preferences returns OpenGL settings to their default status. Reset Photoshop preferences by pressing and holding Shift+Ctrl+Alt (Windows) or Shift+Option+Command (Mac OS) immediately after you start Photoshop.
Click Yes when asked if you want to delete the Adobe Photoshop Settings File.
Retry the function that caused the problem.
Change the OpenGL mode to Basic.
Setting the OpenGL mode to Basic uses the least amount of GPU memory and the most basic GPU feature set.
Close all documents.
Choose Edit > Preferences (Windows) or Photoshop > Preferences (Mac OS)
In the Performance panel, click the GPU Settings Advanced Settings button.
Choose Mode > Basic
Restart Photoshop.
If this solution resolves the problem, switch to Normal mode. See if the issue recurs. If the issue recurs, return to Basic mode.
Note: If you’re changing GPU preferences to troubleshoot a problem, re-launch Photoshop after each change.
If you are using more than one video adapter, remove the additional cards.
Multiple video adapters can cause problems with GPU accelerated or enabled features in Photoshop. It's best to connect two (or more) monitors into one video adapter. If you have to use more than one video adapter, make sure that they are the same make and model. Otherwise, crashes and other problems can occur in Photoshop.
Note: Using two video adapters does not enhance Photoshop's performance.
Check your Cache Levels setting.
If you've set your Cache Levels to 1 in Photoshop preferences, you can experience performance issues with GPU features. Reset Cache Levels to the default setting, which is 4.
Choose Edit > Preferences > Performance (Windows) or Photoshop > Preferences (Mac OS)
In the Performance panel, choose Cache Levels > 4.
The GPU Sniffer
To help guard against Photoshop crashes related to bad GPU hardware or drivers, Photoshop employs a small program called the GPU Sniffer. Every time Photoshop is launched, Photoshop launches the sniffer. The sniffer runs rudimentary tests of the GPU and reports the results to Photoshop. If the sniffer crashes or reports a failure status to Photoshop, Photoshop will not use the GPU. The Use Graphics Hardware checkbox in the Performance panel of the Preferences will be unchecked and disabled.
The first time the sniffer fails, Photoshop will display a dialog indicating that it has detected a problem with the GPU. On subsequent launches the dialog will not appear unless the Photoshop preferences are reset.
If the user corrects the problem, either by replacing the video card or by updating the driver, then the sniffer will pass on the next launch and the Use Graphics Hardware checkbox will be enabled and returned to its previous state (enabled or disabled).
Tested video cards for Photoshop CS6
Adobe tested the following video cards before the release of Photoshop CS6. This document lists the video card by series. While the minimum amount of VRAM supported on video cards for Photoshop CS6 is 256MB, some features require 512MB of VRAM to be enabled.
Note: Adobe tested laptop and desktop versions of the following cards. Be sure to download the latest driver for your specific model. (Laptop and desktop versions have slightly different names.)
nVidia GeForce 8000, 9000, 100, 200, 300, 400, 500 series
nVidia Quadro 400, 600, 2000, 4000 (Mac & Win), CX, 5000, 6000
AMD/ATI Radeon 2000, 3000, 4000, 5000, 6000, 7000 series
AMD/ATI FirePro 3800, 4800, 5800, 7800, 8800, 9800, 3900, 4900, 5900, 7900
Intel Intel HD Graphics, Intel HD Graphics P3000, Intel HD Graphics P4000
Note: ATI X1000 series and nVidia 7000 series cards are no longer being tested and are not officially supported in CS6 – some basic GL functionality may be available for both these cards.
Note: 3Dand some Open GL features are disabled on Windows XP, as stated on : http://labs.adobe.com/technologies/photoshopcs6/

I've had several timeout since the pings were started. Got a some response times > 1ms (nothing greater than 7 or 8ms), but no timeouts.

What is difference between modify and update i am using

hi
what is difference between mofify and update
my requiremen is to have three condition checkec while mofifying or updating from a internal table
the three fields are
cus no
status
date these all are primary key in the database table
so which sould i use modify or update
there might be entry already existing in database table or new entry to be created if already existin it should check on the primary keys and updatat if not it should add a record
pls suggest whihc to use and how to implement the check on teh threee primary key
like if modify ztable from table it_test
now where condition ? can be used or not with modify? and if yes how
if not should i use update will update create a new entry if no entry is there and please give syntex
regards
Arora

Hi Nishant Arora,
Modify: It works in performing two actions.
They are: Insert + Update.
For Example If a record that is exited in database, so you are modifying that record, it updates that particular record.
Similarly, If the is not existed in the database, you are modifying it, it inserts a new record.
Update: Update means just it updates the status, I mean it only updates the record. It doesn't inserts any new record if that particular record is not present in the database.
These are the cases you need to write these statements.

What is Difference between SXMB_MONI and SXMB_MONITOR?

what is Difference between SXMB_MONI and SXMB_MONITOR?
Can any explain to this question.please?

Hello,
Both are same.
SXMB_MONI is area menu which will contain all multiple transactions pertaining to monitoring.
SXMB_MONI contains some functions viz monitoring for Bridging, Archived Msgs, Job overview, persistence layer analysis.
SXI_monitor directly leads to the message monitoring for the IS, which is part of the SXMB_MONI.
SXI_MONITOR directly executes the monitoring report.
Thanks,
