Hierarchies in SAP MDG data model

Hello Gurus,
Could any one please let me know how to create hierarchies in SAP MDG Data models..I have gone though the SAP Help document and but couldn't understand it..If any one has worked on this , please let me know.
Regards,
Raghu.

Hi Jose,
I'll start with simple hierarchy demo containing HIERARCHY NAME, GROUP and OBJECT.[HIERARCHY NAME is the top node, GROUP is the middle node and OBJECT is the end node]
1.In data model, you have to create all the as 3 entity types.
2.In the middle node,i.e. GROUP here, choose the hierarchy option as version dependent or Non-version dependent as per your requirement.
3.In the middlle node,i.e. GROUP here, build hierarchy by assigning
Entity Type for hierarchies ->Entity Type of Node , Use
Here the top node,i.e. HIERARCHY NAME ,will be assigned use as Hierarchy names
You can find related documentation by using F1 help on specific field.
4.Your hierarchy model is now ready.

Needed SAP CRM Data model with Object, Entity and Attribute level details

Hello all,
We are working on a huge IS-U / CRM implementation and we are still in the data gathering phase. The client has a whole load of legacy systems that will be replaced with IS-U and CRM. Right now we are in the process of developing data models using Excel first and then presenting them to the client to go forward from there. For this we need to have all the business objects, entities and their attributes.
I know about the SD11 transaction, but we don't have a CRM system yet. My colleagues have access to a German ERP system and they were able to get models for HR, FI and Asset management. I tried for the Business partner / customer in there, but the models were not proper.
So, once again, I need the specific data models out of SD 11 for CRM business partner. If anybody has the information, please do pass it on to me as I need them urgently. It would be a great help if somebody can do so.
Regards
Rajesh

I suggest the following:
Please, check whether the system works if you activate the implementation BUPA_F4_AUGRP.
In addition check the notes 559662, 674869 and 782927. Maybe the notes are already implemented but you can try then the implementation of the BADI (SE19). It should resolve your issue.
I have implemented this Badi solution before, and after activation; the search help ; nor search result list did NOT show any Business partners anymore that had an authorization group I was not allowed to see.

Needed - BW data model and list of Dimensions and Fact table from BW

Dear Friends,
Can somebody please share SAP BW DATA MODEL (LOGICAL) and share the list of DIMENSION and FACT tables exist in BW?
I don't have access to SAP or SAP BW and I am building data-mart and SAP FI/CO will be the source.
Thank you very much in advance.
Regards,
Nitin
Edited by: Nitin Baradia on Apr 5, 2010 9:08 AM

Let me rephrase.
I got an EarlyWatch that said my dimensions on one of cube were too big. I ran SAP_INFOCUBE_DESIGNS in SE38 in my development box and that confirmed it.
So, I redesigned the cube, reactivated it and reloaded it. I then ran SAP_INFOCUBE_DESIGNS again. The cube doesn't even show up on it. I suspect I have to trigger something in BW to make it populate for that cube. How do I make that happen manually?
Thanks.

Tools for data modeling

Hi,
Can any one tell me if there are any specific tools used for logical data modeling in SAP BW data modeling . I have used Erwin as a data modeling tool for implentation of data ware house, I would like to know if there are any specific tools for SAP BW implementations.
Response appreciated

Can SAP leverage MM and classification (CL-system) data-model?

Dear all,
At the moment Im working for a telecom company, setting up the Functional Management department activities to manage 2nd line support calls, and general overall application functional support.
One of the issues is simplifying the work of monitoring Item (products, articles etc.) Master Data. Below you can see the data model where Items, their classes, the characteristics of classes and prices are stored.
The Legacy system has the following data-model (as ERD, <a href="http://sapparking2007.freehostia.com/LegacyModel.JPG">LegacyModel</a> )
Main Product (i.e. Nokia 6110)
     - has zero, one or more Characteristics (i.e. 220v cord, 3v battery etc.)
     - has zero, one or more Variants (i.e. Nokia 6110i, Black, Red etc.)
     A Variant (Nokia 6110i, Black)
          - has zero, one or more Characteristics (i.e. 200h stand by time etc.)
          - has zero, one or more Deliveries (i.e. we sell a package)
          A Delivery (certain combination of a package : Nokia 6110i, Red, Prepaid, 1 year)
               - Has zero, one or more Characteristics (i.e. prepaid simcard, free service etc.)
               - Has zero, one or more Delivery Prices (i.e. prices)
               A Delivery Price
                    - Has zero, one or more Characteristics (i.e. 1 month warenty)
                    - Has zero, one or more Prices (i.e. offer price, sales, periods)
Well, almost perfectly normalised data-model.
The implementation in SAP is as follows:
Main Products , Variant and Deliveries are all stored in table MARA.
Product is Artikeltype Z01A,
Variant is type KMAT,
Deliveries is type HAVA and DIEN.
See image:
<a href="http://sapparking2007.freehostia.com/Model01.JPG">Current Data Model</a>
The Characteristics are stored in table CABN etc
The prices are stored in the SD table KONP .. (price condition). etc.
The MARA table is connected to Classes table (KSSK) via the INOB table.
Classes are connected to Classes with in de KSSK table.
The filed that stores Class in the KSSK and the field that stores the Class below are 2 different type of fields (18C , and 50CN) and they would simply wont join in a SAP query.
The filed that stores Item to Class in the INOB and the field that stores the Class in the KSSK are 2 different type of fields (18C , and 50CN) and they would also wont join in a SAP query.
Therefore we have created extra Z. Tables (Types actually) that does the join for us.
Functional Management personnel are not ABAP and SQL people. So we have to keep it simple.
After a training session it proved to be still too complicated. After a Change Request, to create the product structure in a separated, single table, has resulted in a batch job, that create the file periodically, but not all of it. And at the end, you never know if your data is up-to-date.
To me it seems logical to add a (derived) field to the KSSK and the INOB to accumulate the underlying class with the same attributes as the MARA and KSSK, so it can be properly joined. But here there is too much resistant in conjunction with SAP releases etc. AND it seem to be impossible (not sure) to define a type table with a derived field.
To let programmers produce more ABAP is not a clean option either, and yes I realise one can create a sap query on a single table, and add a long SQL statement on Record level.
So the question:
-     Is this implementation the best possible in SAP?
-     How to overcome the unjoinable friendly database?
In other query tools it is possible to create tables as output (on the fly), where the tables can be used as input tables in a next query, and can be joined further.
-     Is this somehow possible in SAP?
I wonder if anyone can shade some light on this approach. We have 2 FTE to monitor 2.5 million products combinations, and the propagation of this data to over 30 sales channels daily.
Thank you in advance for taking the time!
Kind Regards,
Doron.

Data model design in SAP BI

Hi All,
I have one requirement to design the data model for BI. How to design a dataflow in BI. I know dataflow is different from data model. Could you pls let me know hoe to design it.
Is there any model available ...so that i can refer. if not let me know clearly what is a datamodel and how to design it.
Thanks,
Jack

Migrating SAP BW into Oracle data model

We have a requirement where the exisiting data from SAP BW needs to be migrated into Oracle. Since I do not have any prior SAP BW experience, I wanted to ask the forum on what their thoughts are in converting the data model from SAP BW into Oracle. Would that be straight forward conversion for the fact and dimension tables into Oracle or are there certain things we need keep in mind while designing the data model in Oracle. For ex: indexes, keys, attributes etc if they are handled any differently between the two systems.

Hi
ERwin will not give you the functionality to derive the logical data model from SAP BW automatically, however Saphir from Silwood Technology (www.silwoodtechnology.com) does allow you to extract the detailed metadata from the SAP BW system ( as well as from other major standard or customised ERP applications - SAP itself, Oracle, Siebel, Peoplesoft and JD Edwards). Once this information is brought into its own repository, Saphir provides a range of powerful search and view capabilities to allow you to isolate the data you are interested in and then export that information to ERwin (or any other leading Modeling tool).
Saphir will provide you with details of the relationships and detailed definitions within SAP BW.
Hope this helps

SSM 7.0 - Copy SAP BI data into PAS or Create Dim. Model viewing BI Data

I am using SSM 7.0 with SAP BI. Is there some best practice / direction / comments on making a decision between:
#1 - Duplicate SAP BI data into PAS Dimensional Model
- Create an InfoCube in SAP BI
- Create the model connection required by BI Connection
- Copy the required SAP BW/BI InfoCube information into a PAS Model using the BI Connector
- Create KPIs based on this model connection
or
#2 - Make SAP BI data visible in PAS Dimensional Model (no data stored in PAS)
- Create an InfoCube in SAP BI
- Create a Dimensional Model based on this InfoCube using a Link ID and the SCHEMA commands
- Create a model connection to make data in InfoCube available in SSM
- Create KPIs based on this model connection
My thinking is that if the volume of data is low then not actually having to go to the trouble of duplicating the data in SSM would work well - with the benefit that the information is updated as soon as the SAP BI InfoCube is updated.
(At the moment I have tried #2 but so far not failed to create an KPIs - I am wondering if the Key Figures in the InfoCube need to use a particular naming standard)

Hi Mark,
See the link below for a Best practice document that is available here in SDN. Although you can use queries that already exist in BW, it is usually better to create new queries adjusted to the kind of information you want to provide in SM. There are a few rules you need to follow when creating such queries, but there is actually no naming convention for its Key-Figures.

Transporting Data models in SAP HANA

Hi All,
I was trying to understand how data models can be transported in SAP HANA and came across the different options in the Export option of hana Studio like exporting with Delivery unit, Developer mode, etc.. Can someone please elaborate on the differences between each and the scenrio when each should be used?
Thanks,
Sam

No Justin, haven't used in any "production" environments till now since the client am working for is still to be upgraded to SP7. At internal system we are doing some R&D in those lines and developing artifacts from "Development" perspective.
Here i shared this link for reference itself.
Also i think using Development perspective for modelling is what is being suggested going forward in blogs like this
6 Golden Rules for New SAP HANA Developers
May be John Appleby and his team are already using "Development" perspective consistently

Hi Patrick ,
What user did you use to start JSPM? Was it <sid>adm? Also based on the error it seems there is something wrong with DataModel.xml JSPM uses. And you've mentioned it was copied from another system if I get it right.
So as a quick workaround you could try removing:
- Jspm.DataModel.xml
- Jspm.J2EE.DataModel.xml
- Jspm.JSPM.DataModel.xml
from ../j2ee/JSPM/data/variables directory and give JSPM another try.
Please make sure the rest of the XMLs are in place otherwise JSPM won't start.

Vasil

SAP BW SRM Workflow data model design

Hi All,
I have a requirement from my client to design SAP BW SRM Work flow report, in output user is interested for document flow/chain starting from Shopping cart (SC) - Bid invitation (RFx) - Bid (RFx responses) - Purchase order (PO) - Confirmation. There are standard datasources and DSO's for the same but I want to check experts ideas on data model design. I am thinking to build infosets on top of DSO's but it will impact Query performance as data volume for sure will be more and will increase down the line. In addition I need to consider below exceptions or restrictions as well:
1. Document may/may not start with SC for example one possibility is document start at SC and end at Confirmation or start at RFx and end at PO etc.
2. User is expected to see below various possibilities of document chain in report output:
SC - RFx - RFx responses - PO - Confirmation or
SC - RFx - RFx responses or
SC - PO - Confirmation or
SC - RFx - RFx responses - PO
SC - RFx or
RFx - RFx responses or
RFx or
RFx - RFx responses - PO or
RFx - RFx responses - PO - Confir or
PO - Confiramtion or
PO
your help and ideas on this is greatly appreciated
Thanks and Regards,

Hi All,
Any inputs or ideas on the data model design? Thanks for your help in advance

AllFusion Erwin Data Modeler Connection to SAP NW2004s Systems

We would like to use a data modeling product that we purchased for many of our SAP NW systems. We understand that there may be some restrictions on DB direct user connections and would like to confirm the following from those that may have exposure in this area:
1. If we connection the DM product to SAP, are there any restrictions on the data that is read from the SAP DB?
2. Are we violating any SAP license agreement by using the third party tool for data modeling on our SAP NW systems (since it will require a DB connection)?
3. Any other helpful information?
Any guidance would be very much appreciated.
Thanks and best regards,
Chris

Hi Chris,
How does your DM product plan on "connecting" to the SAP applications? Most of the time, SAP applications provide Remote Function Calls (RFC) (i.e. in the programming world, methods) for programmers to call in order to push or pull data to itself. There are no restrictions here aside from the normal authorizations given to access data on the application. Although SAP discourages any direct manipulations directly to the database layer.

Copy data models and reports from BW 3.1 to NW 2004s

Hi experts,
Our client has two BW servers: BW 3.1 and BI 7. BW 3.1 contains lots of data models and reports. And the BI 7 server is newly installed.
Now we want to copy these data models and reports from BW 3.1 to the new BI 7 server. Are there any solutions for this?
Thank you very much in advance.

Hi Frank,
Sounds like a cross version transport is needed.
This is a solution we have used to do what you want to do:-
Create and release a transport as per normal.
Copy and transport the files from the source system (BW 3.1) e.g /usr/sap/trans/data & /usr/sap/trans/cofiles to the same folders on the target system.
Basis help is needed here.
From here onwards using stms_import should help you in the normal manner.
Works a treat.
Have transported the following all correctly appearing as 3.x data models in NW2004s.
DSO objects.
Cubes
Transfer/Update rules
Reports.
Cheers,
Pom
