MDM Sizing Query

I have done a sizing for 500K records spanning across three domains - customer, material, vendor domains with material being the major contributor of 400K records.
For memory, sizing (based on MDM sizing guide) comes to 16GB. I find it quite low considering that material could even store rich content.
Is this right numbers? Could you help me with your sizing numbers so that i can do a match up.

Hi Experts,
Please, provide me with some Examples for MDM-Validations Query or some material with some detailed Example of Queries
written .... for example Query for Compulsary field .... etc...
regards,
Jay.

Hi Jay,
As you seem to be clear with alternatives, i would be sharing about Masterdata management (i.e. MDM) from my perspective.
In general,benefits of keeping Master data in 1 place is
Conformance/Auditing
Single view of customer
Global data synchronization efforts
Accurate reporting
Consolidation after mergers and acquisitions
Reduced effort to consolidate information
Reduced cleansing/mapping of information
Increased efficiency
Reduced costs overall.
with this much details you can refer to the URLs which have detailed infomation about every aspects of MDM:

Abap MDM API query with OR operation

Hi experts,
not sure this is the proper section for the thread, anyway; dealing with ABAP MDM API, is there a way to build up a query which involves several clause in OR conjunction?
This is the scenario: I've got to extract several items on the basis of exact product codes. Tipically, I've got huge vectors of hundreds of product codes; actually, I could easily retrieve data by looping over them and, for each code, perform a query on MDM via QUERY method building the clause as follows:
      ls_query-parameter_code = 'MDMSRM_PART_NO'. "Field code
       ls_query-operator        = 'EQ'.   "Contains
       ls_query-dimension_type = mdmif_search_dim_field.      "Fieldsearch
       ls_query-constraint_type = mdmif_search_constr_text.    "Text search
       lv_text = wa_codes-product_code.
       GET REFERENCE OF lv_text INTO ls_query-value_low.
       APPEND ls_query TO lt_query.
This will however result in hundreds of query in the LOOP itself.
Is there any way to build a query with OR operators ?
Thanks,
M.

Hi,
I see you are not clearing your local structure "ls_query". This could be reason of problem, try this and let us know the result:
DATA lt_query                  TYPE mdm_query_table.
DATA ls_query                 TYPE mdm_query.
DATA lv_search_text       TYPE string.
DATA lt_result_set            TYPE mdm_search_result_table.
DATA ls_result_set           LIKE LINE OF lt_result_set.
Fill query structure with FIRST parameter
    ls_query-parameter_code = 'Name'.
    ls_query-operator        = 'CS'.
    ls_query-dimension_type = mdmif_search_dim_field.
    ls_query-constraint_type = mdmif_search_constr_text.
    lv_search_text = 'BMW'.
    GET REFERENCE OF lv_search_text INTO ls_query-value_low.
    APPEND ls_query TO lt_query.
CLEAR ls_query.
Fill query structure with SECOND parameter
    ls_query-parameter_code = 'Model'.
    ls_query-operator        = 'CS'.
    ls_query-dimension_type = mdmif_search_dim_field.
    ls_query-constraint_type = mdmif_search_constr_text.
    lv_search_text = '2009'.
    GET REFERENCE OF lv_search_text INTO ls_query-value_low.
    APPEND ls_query TO lt_query.
CLEAR ls_query.
Query on records (search for value 'BMW' model '2009' in table Products)
    CALL METHOD lr_api->mo_core_service->query
      EXPORTING
        iv_object_type_code = 'Products'
        it_query            = lt_query
      IMPORTING
        et_result_set       = lt_result_set.

SRM 7.0 and SRM MDM Installation query

Hi,
I have installed Both AS ABAP and AS JAVA Stack separately and going forward I need to know
1) Do I need to install any other servers other than this like EP and PI etc?
2) I also wanted to install SRM MDM, for that I have gone through some documents and threads and found that
Prerequisites
1. SRM Server- Installed with ORACLE database
2) For SRM MDM
Ø        Download the SRM-MDM Catalog 2.0 installable from Market Place-- Done
Ø         Install the MDM Server and other GUI Clients--Done
Ø     UnArchive the SRM-MDM repository available with the installables only
                     Need help for
             . Not able to find DBMS server
             . User
               . Password for DBMS setting
Ø      Deploy the two SCA files - MDMJavaAPI and SRMMDMCAT on WAS and restart the Portal- Done
Ø        Access the Config UI by using the URL http://:/SRM-MDM/SRM_MDM and change the layout as per the requirement. In this you can specify the fields to be displayed for Search, type of UI etc for the particular user
. Where I can get the "Port"
Will follow the below steps once the above issues are resolved
*Create the Web Service in SRM system and specify all the required
parameters. You should get the SRM-MDM configuration guide from Market
Place.
*Change the Org Plan in SRM to assign the Catalog to the SRM users.
*Login into EBP and select SHOP, you should get the SRM-MDM Catalog link
if all the configurations are there in place.)
3. Web Application Server
> Is seperate WAS required even after installing SRM AS JAVA stack, if yes what to install
       4) In the market place I have found that SRM MDM install.exe and in that there are two options to execute. Install MDM
           . Install SRM MDM
          Do I need to install both or only one or is this not required, if I install SRM MDM my question is what is the use of
          the above point 2 steps process this one

As you have already installed Java stack then it will be your EP. You don't need PI for SRM MDM.

The DBMS Server property defines the network identification string of the DBMS instance / machine / server that is used by the DBMSspecific client on the MDM Server machine to connect to the DBMS. The brand of DBMS on which the repository is running is shown in the DBMS Type property.
NOTE ►► When you mount two MDM repositories with the same name (but located on different DBMS Servers) on the same MDM Server, MDM distinguishes them in the Console Hierarchy pane by appending the name of the DBMS Server in angular brackets to the repository name (e.g. u201Crepository <server>u201D).

MDM scenario query

Hi All,
        I wanted to understand how a MDM repository designed for the following scenario:
I have 4 remote systems, A,B,C and D.
For example ,lets take a customer Master data.
I have 30 fields for the custmer,out of which the field "payment term " is different for each remote system.For eg,payment term 15 in system A,means as follows:
Remote System                     Value
A                                              15
B                                               B1
C                                               C1
D                                               D1
And there are lots of payment terms which are dynamic.
We can do it by having a lookup table called PaymentTerms with a field "PaymentTerm" for the payment term and managing four keys on each record(say for above example,an record entry for 15 with four keys as:
A 15
B   B1
C C1
D D1
So when I mark the field as a display field, it will appear as 15 for all records .which have payment term as either 15,B1,C1 or D1 as data cn be fed from any of the four system.
That will be confusing for the MDM data administrator as for a record coming from system B,should be B1 and not 15.
Please let me know if my scenario is unclear.
Edited by: Premjit Mishra on Feb 9, 2011 11:45 AM

Hello Premjit Mishra
For me it's clear
Create next LUT"Payment term":
System - related (LUT) - name of system( should be related lut with list of our system names) - Display field (1) - order in DM
Term - (text or real or measure) - name of payment term or, maybe, value -   Display field (2)
XXX- - dome another dfields if you want
Create in your main table filed like "Payment term"
type = LUT (Flat)
lut name =Payment term
Value selection= Mini-search

MDM listener Query

Hi All,
A MDM listener listening for record updates;
Will it take record updates within a checked out record (like assignments) Or Will it
Take as a record update when the entire record is checked in?
Regards,
nitesh

Hello Nitesh
SAP MDM support check out mechanism for all record modifications
If you update no checked out record it record will lock for another user
If record checked out all user work with copies of that record
When you insert somthing to checked out record and then press save fire "Error" validators then fire workflow "Modify record"
after that(if you havn't error) your changes will appliy to MAIN(checked out) record.
If you used not exclusive checked out insert some changes to record can different users but not same time
in that case SAP MDM create one copy main record(checked out) for each user
and after insert changes applied it to main record from each copy
last changes applied last to main record

MDM Adapter query

Hi Experts,
My scenario is MDM to JMS(MQ). MDM side sends file in a MDM adapter, now the problem lies in the part that PI has to send files based upon timestamp order and syndicate them to Mainframe. Now, for File Adapter there are options in which we can do so but I do not have an idea how it can be done in a MDM adapter.
Please let me know.
Regards,
Aniruddha

Please refer the links for MDM-PI adapter configuration you dont need a sender file adapter now

Portal Sizing Query

Dear All,
I am trying to do an initial sizing for Portal 7.0. The total user base is 75000. The logons/hour is 9375 (75000/8).The concurrent users are also taken us 9375, though they could be less.The users will use the Travel expense planning application.There is no KM and no other applications.
As per the quick sizer with a think time of 200 secs and concurrent users 9375 and logon/hour=9375, the SAPS is 4600 and 17GB of RAM. is this a realistic estimate?.
For the 4600 SAPS, the server configuration could be
1. 1 DB+CI Server 2 CPU/4GB
2. 4 Application Servers: 2 CPU/4GB each.
Will the above servers support the 9375 concurrent users?.
Pl share your thought.
Thanks in advance.

Velu

Hi Velu,
You have to also into consideration
01) no. of custom java applictions
02) any business packages
03) user growth .. (futuristic view)

MDM Limitation Maximum number of records ?

Hello,
we have requirement to implement SAP MDM. Customer has 20 million entries for its customer data. Can MDM support this? I heard maximum MDM can handle only 6 millions entries, above that it cannot work.
Please confirm.

Hi Dony,
I think you need to do sizing as per number of records.
https://websmp109.sap-ag.de/~sapidb/011000358700001921872008E
You need SAP Service Market place SUID and Password for open above link (MDM sizing guide).
I think you can check with SAP if you still have doubts regarding the number of records.
Please find similar thread as given below:
Does MDM 7.1 have any limitations re: number of records per repository?
Hope this helps..

SAPS in sizing Guide

Hi
Can you please help me to find out more details about processor in MDM sizing?
From CPU I got result: 6500 I do not know how can I find processor, can you help me ?
I found something here:
http://aroundsap.blogspot.com/2007/09/sap-hardware-sizing-and-benchmarking.html
but that is not exactly what I am looking for.
Many thanks for finding CPU type.
My result for RAM is 10 GB do you think that is correct, we have 8 repositories?
I think my calculation is correct - I just woult like to have others consultancy
Thank you in advance.
Have a nice day.

Michal

Hi ,
SAP periodically benchmarks different servers and indicates their SAPS. Visit:
http://www.sap.com/solutions/benchmark/index.epx
Select on the right under SD Benchmarks ->"SD two-tier results" (as NW MDM is more similar to a 2 tier architecture).
A table will open with all benchmarked server's SAPS results.
The list updates periodically.
You can download it to a text delimited file.
Hard to indicate regarding the RAM you received without having more details.
The calculation should be done for each repository on the server separately and then added up.
Generally, 10GB memory seems a resonable result.

Hedda Cohen.

Sharing Import Server with MDM

Is it feasible to have a shared import server used for both MDM and SRM-MDM Catalog?
The SRM-MDM sizing guide recommends an independent server just for the MDIS (for production). I am wondering if I could just use the server we have for our MDM system.

Hi,
You can use same Import Server but it depends on how often and how many items are going to import in MDM scenario side.

Masa

MDM Database command execution error. A SQL statement failed to execute

Hi,
When we tried to execute an MDM Java query modify/create, we get the following dump.
Is this anything to do with the parameters that we pass or is it something to do with the database ?
We have checked the code and we do not find anything wrong with the code at all.
We are using Java API 5.5.63.73 and calling MDM API's using WebDynpro for Java.
I have noticed this issue has been raised here as well :
Database command execution error. (While mounting a repository)
com.sap.mdm.commands.CommandException:
com.sap.mdm.internal.protocol.manual.ServerException: Database command execution error. A SQL
statement failed to execute. The actual error may have been written to a log file. at

Regards,
Subramanian V.
Edited by: Subramanian Venkateswaran on Dec 10, 2008 8:11 PM

Hi Subramanian ,
The error looks more like a problem with the data base or MDM system rather than the java code.
Which is the underlying database you are using with MDM? As some users have faced some difficulties when working with the DB2 Data base,If this is the data base you too are working upon then may be the issue could be similar,if possible try using the Oracle or SQL data base as these databse show more compatibility than a DB2 when working with MDM .
Also check the MDM users autorization and authentication to modifyor create recordrs in MDM.try given the user the ADMIN rights,and tehn try and see if teh user is able to modify/Create the mdm records.
Lastly you can check the database instance and listener configuration correctly.try restarting the Database service form the system if possible.
Hope It Helped
Thanks & Regards

Who can tell me the difference between MDM,BW and ODS

What's the difference between MDM/BW/ODS,and what aspect/domain does each of them emphasize.

Thank Dirk,Anil for your wonderful answer.
After study these docs on sap.com and your reply,I have other questions to ask:
1. If I use MDM as a Enterprise's Data center repository,Is that mean I can give up other database such as Oracle,SQL Server,and build new application or shift those regacy non-SAP applications on MDM gradually,you know,if I retain these DB,I should syncharonize them cautiously,and it can not avoid "dirty data" between heterogeneous systems.
Consider such a scenario,application A request data from MDM to modify,application B request the same data from MDM to query,then "dirty data" happened?
So,I think if I use MDM as center data repository,then I should give up other DB,and these non-SAP systems should reference these data and deal its own business matter.
2.When I implement MDM,Would the data in SAP R/3(such as PM/MM/FI/CO) also be replicated to MDM,then shared to other non-SAP systems?or these data needn't synchronize to MDM?
3.consider such a scenario,I need SAP R/3 data to share with other non-SAP system,besides XI,should I need MDM,using MDM to implement data management and sharing.
4.Dirk has noticed "MDM could also mean Meta Data Model ",so I want to ask if MDM fully compatiable with CIM(common information model) and I can create complex objected-oriented data and mutiple relationship in it?
thanx for your answer again,Best regards
jiansen

Network bandwidth requirement between MDM server and MDM Clients

The MDM Sizing document for 5.5 states that 'a network connection between MDM Servers and MDM clients should be at least 100 Mbps'. Is this true? This would preclude MDM being offered as a hosted service. I'm interested in MDM Catalogue for SRM, so the catalogue content managers would need the import and data manager clients.

One factor I noticed, in our project...
I would recommend a 4 GB RAM for someone who is working with Import Manager.
As far as the Network connection goes, I am not sure what the requirements are.
We have faced several issues when the end user's laptop are less than 2 GB.
If someone is working with Image Manager, then I would recommend 4GB.
For bulk imports, I would use Import Server.

MDM Performance problems

Hi All:
We are suffering terrible connections problem when we tried to connect using MDM Data Manager to the MDM Server. To give an example, sometime we wait for more than 10 minutes to complete the connection and the repository load. This obviously would make sense if we would have all the records loaded and we would have an enormous repository to be loaded; however this is not the case.
Have you ever performed repository loading problems or any other sort of performance problem. How are you handling it? What sort of best practices have you implemented?
Kind regards
Gonzalo Perez-Prim

Have you sized your MDM Server properly?
MDM Sizing guide is available in Service Market place.
For running client applications, I would recommend atleast 2 Gb ram.
CPU Consumption is high when you are executing some matching strategies or Import Manager.
If the repository has lot of binary data(imange) then the archiving would take a lot of time. We are experiencing an hour to archive a repository and 20 to 25 minutes to load the repository.
This is after the fact that the sizing was done properly.
