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.

Oracle client for CA Erwin data modeler

Does anyone know how to install and configure oracle client for Erwin data modeler?
CA tech support says check with oracle

>
I need some help understanding what client means.
>
Client is any server that connects to a database. I am assuming that CA will be installed on a Windows XP machine and it will connect to a remote database on another server. I am assuming since you have not provided any details.

I can upgrade to 11g database. No problem

OK - not sure what this has to do with your issue.
>
I am looking for the oracle software that connects to CA Erwin

See my links posted above
>
I am not looking for Oracle database install

The client install does not install a database - it installs the necessary components needed to connect to a remote Oracle database.

Please be more specific.

More specific with what ? The more lucid details your provide, the better the quality of the responses on these forums.

The Data Model connection could not be created

Hello,
Using powerquery, I am trying to access daily logs conveniently, the are over 24m records in a month.
I have selected the columns i need, and checked the box ' load data to Model', Once the query has ran it returns the error, "The Data Model connection could not be created".
Thank you for any help on this :)

This is a tough one because as an add-in, we can't get much information from the API for failures like this. Our general recommendation for people working with big data sets is to use 64-bit Excel. I realize that's a big hammer, but it might be your only
option if you need to work with a 24 million row data set.
Another option (which you may have already done) is to filter and aggregate that dataset as much as possible before adding it back into Excel. The analysis done inside the Power Query editor is less likely to negatively affect the working set on your machine.
(It does depend how the query is built and where the data is come from. If we have to pull all the data into memory to do some of the operations then it won't help at all.)

Thank you very much!

Hi Holger.
this issue is related to the RFC but not the one which is communicating from BI to R/3 rather the one which is communicating from R/3 to BI follow these steps.
1. check your BI system logical name from the myself source system.
2. go the ECC and run the transaction sm59
3. go the ABAP Connection folder and search for your RFC which name would be by default as per your BI logical system name.
4. double click it and edit it now check whether the Target hostname or ip is OK.
5. In the logon tab check the client number User and password settings.
Save it and test it with both Connection Test and Remote Logon.
if every thing work fine i hope your problem will be solved.
kind regards,
Zeeshan

Hi ,
I think SLD,s/w Catalog and Creating Logical Systems were Configured,
Go through the Following Steps Like,
-- General Data, Enter the Client of the System and Client No. (JCo Connection is Pointing to)
--J2EE Cluster, Select the J2EE Cluster you wish the JCo destination to be assigned
-- Select the Destination Type, Either Application/Dictionary data
-- Appl.Server, You may only select Servers/Logon Groups From the Drop down list that have first been defined as technical Systems in SLD.
-- Message Server, Application Data JCo destination is connected must have atleast one logon group.( if this is not done ,use SMLG transaction code to create in SAP System)
--Security, If you have selected connection Type as Application Data , then in the Security Screen you would appear Authentication Techniques and select a appropriate one .
if you have selected connection type as a Dictionary meta data then provide User Name and Password
If this is useful to you ,don't forget to award Points

Metadata from Erwin data model to BO Designer

Hi,
I have generated a CWM XML file from ErWin, that contains the physical table names of all tables in the model. I am using universe "metadata exchange" to convert this data model into a universe. The first time "create universe" is happening fine.
The problem is while updating the model.
There is a "owner" field specified in Erwin table. If thats left empty, the tables in the universe schema are generated as "unnamed_NNN.<TABLE_NAME>". (NNN is a number)
Obviously I have to remove the unnamed_NNN from the tables so that it will recognise the default database for the connection.
Say, the metadata has undergone some changes and we want to update the universe with new metadata. I used "metadata exchange" to update the universe from the model. At this time, it creates a new table and class with "unnamed_NNN.<TABLE_NAME>", instead of updating my TABLE_NAME class and object definition with the changed metadata.
This basically means update doesn't function as expected. Can anyone suggest if this is a limitation of the metadata exchange or am I doing something wrong ?

I am trying to do the same thing using ER/Studio and have the same problem.
In addition, the joins from the model are not being reflected in the universe.

Hi,
With regards to your statemetn "SDN downloaded document says to Generate Webservice URL through ABAP" <- can you tell me more please? references/links/attachment?
As far as I am aware, that the type of web service required for integration it a 'normal' Netweaver Web app server web service.
There are limitations about the complexity of the WSDL - see Notes:
1653655 - Limitations in Web Service WSDL URL usage in Xcelsius 4.0
1703839 - Limitations of Web service usage in Xcelsius / Dashboard Design
also , changes between SAP versions requires reworking the WSDL
Note 1625091 - The WSDL URL for web service which generated in SAP Enterprise Central Component cannot be loaded into Xcelsius

Connect one SAP BW system to multiple R/3 systems

Hi All,
Has anyone done a connection of one SAP BW system to multiple SAP R/3 systems. I know it is theretically possible, but please let me know if anybody has experience of doing it. Our scenario is that take HR data from one R/3 system and other modules data from another R/3 system.
Also please let me know the steps of connecting the systems, the do's and dont's and any special config that needs to be done.
Also what are the risks?
Thanks in advance.
Regards,
Rajib

Hello,
after you connected the new source system, there are some additional steps to do. But this is common for all new source systems:
-> Set conversion of source system names in RSA1. This is necessary for Transport of Objects in BW. Go to RSA1->Tools->Conversion of Logical System Names
-> Set Assignment of Source System to Source System ID. You also find this under RSA1-> Tools. This is only important if you use a Source system ID like in IO 0SOURSYSTEM.
-> Replicate Application Component Structure of DataSources. Therefore go to DataSources. Select your Source System (If you are on BI 7.0) and go to the Header, right click you mouse and replicate Tree Metadata and then replicate DataSource.

Data Reconciliation Node on SAP Source System

Hi Gurus,
I'm working on Data Reconciliation between SAP BI and SAP R3 systems. I've read on the forum that the reconciliation DataSource technology is available as of PI-BASIS 2005.1 / SAP NetWeaver 2004s. I'm using
SW Comp Release Level Highest Support Desc
PI_BASIS 2005_1_640 0017 SAPKIPYJ6H Basis Plug-In (PI_BASIS) 2005_1_640
I wonder that I cannot see the Data Reconciliation Node in the transaction RSA6 in the SAP Source System. Please throw some light on this whether I need to activate them.
Thanks & Regards,
Ash.

Hi Sunny,
Thanks for your response. Can you suggest me what should I do to get those DataSources? Are there any patches that SAP has released to overcome this problem for lower versions as the one which I'm using?
Thanks,
Ash.

Spread the Data Loads in a SAP BW System

Gurus,
I want to spread the data loads in our BW system, as a BASIS person how do I identify the jobs if they are full loads or delta loads, our goal is to make the load on the system to be evenly distributed as we see too many data loads starting and running around the same time. Can you suggest a right approach to achieve our goal.
Thanks in advance
Siva

Hello Siva,
As already mentioned the solution is to include the different steps of the data flow, extraction , ODS activation , rollup etc
in process chains and schedule these chains to run at differet times so that they do not place too much load on the system.
If the problem is specific to data loads on the extraction step then I guess that maybe you see the resource problem on the
source system side, if you don't have the load distribtion switched on in the RFC connection to the source system it is
possible that you can specify that the source system extraxction jobs are executed on a particular application server,
please see the information in the 'Solution' part of the note 147104 and read it carefully.
Best Regards,
Des

All Fusion Erwin data modeller to Oracle 10g connection.

Hi,
I have instaled Erwin Datamodeller Release 7 successfully .That is a trial version.When i try to connect to Oracle from Erwin,it gives an error that ora7nt.dll is not installed and contact the Oracle DBA. I could not find any ora7nt.dll in Oracle Homes.Did any of you face this problem and please help me.

Hi Selva,
This is a forum for Designer, not CASE tools in general. I suggest you take a look at the http://www.infoadvisors.com/ site, as that has an Erwin Users Discussion Group (you'll need to register) or talk to your technical support contact at Erwin.

Edge 3.1 Data Services connection to SAP ECC 5.0 on AIX server

I've got a client who is trying to create a Data Services extract from an SAP ECC 5.0 system on an AIX server. The Data Services is installed on a Windows box and is the Edge 3.1 version. He is able to connect to the SAP datastore, is able to import the metadata for a table and browse the data, but the data transport in the R/3 Data Flow fails due to a permissions problem on the file generated in the working directory on the SAP server (as indicated by the Data Services error message).
We have confirmed that the file can be opened and modified by the same user that the Data Integration service is running under. I have also duplicated his environment and settings in a sandbox virtual machine, except that our SAP ECC 6.0 system is running on MS Windows Server 2003, and the transfer works fine in that environment.
Does anyone know how to resolve this issue? Is there a permissions setting we're missing?

Simply means that in the case you have more than one instance you need to shutdown down the instance you are working on and all the other ones too.
