Combining two ECC systems

Hi Gurus,
There are two ECC systems for Different Regions in my company for some years. Now we plan to combine the two systems into one. then remove one system
Do you have any document/suggestions for this kind of project? Very appreciate your inputs

Connect two ECC systems with one SAP CRM 7.0

Hi Gurus!
I have to do a customizing for connect two ECC 6.0 and one SAP CRM 7.0, only I need the organizational structure from both systems and they need update when the structure from CRM has changes. The business partner goes to ECCs system by PI interfaces.
Both organization models are different, so I have to maintain and update depending the changes in the business.
But I don't know if this is possible, I don't know if we can do this by Middleware, ALE or PI.
Can you please, give your oppinion about this topic?
Best regards,

Hi Eugenia,
Please see note 1084315 which descriibes the the multiple backend scenario.
This should be relevant here.

ME 5.2 connection with two ECC systems

Hi Sergiy/Experts,
Need to connect ME 5.2 system with two ECC & SCM systems for a scenario. Is it possible to connect?
During SAPMEINT standard interface we get connection credentials point for only one ECC system.
How I can meet the scenario for ECC system?
will appreciate your help.
Thanks in advance

Hi,
Yes, it is possible. See my answer here:
http://scn.sap.com/message/14408145#14408145
There is a design limitation: plants must be unique across the different ERPs connected to the same SAPMEINT.

Same material number Ciffing from different ECC system

Hello Gurus,
I have APO system connected with two ECC system.
If there is a material with the same name in both the system how does the APO system finds the respective system.
Even if I assign BSG for the logical systems, to which system will the transaction data will be transferred after planning?
Thanks,
Siva.

Although I do not have real-time experience working in this kind of scenario from what I understand there will be two product-codes based on the BSG.
Eg. HAMMER@BSG1 will be the Product code for material HAMMER coming from your first ECC system which is mapped to BSG1 and HAMMER@BSG2 will be the product code for material HAMMER comping from the other second ECC system that is mapped to BSG2.
Transaction data will then flow back from APO to respective ECC system based on the BSG mapping. Note in the Distribution Definition you maintain the connected ECC logical system name as well.
Hope this helps.
Thanks,
Somnath

PO No range when we ink two SRM system with One ECC system

Hello Experts,
We have a client requirement to link Two SRM Systems with One ECC system.
In this case what number range we need to maintain in both SRM systems for PO.
-The number range of ECC PO should get update whenver the PO is transferred from any of the two SRM system.
-We have Extended classic scenario.
-Also PO Doc type is going to be same.
Can we handle this by increasing the buffer of the number range in one of the SRM system?
Any idea...pls help urgently.
Best Regards,
Anil
Edited by: anil.s.verma on Oct 1, 2010 4:33 PM

Hello Anil,
Being in Extended Classic Scenario (leading PO being in SRM, R/3 PO number range is concidered as external because PO number is given by SRM), the only solution for you is to:
1- give same number range interval for PO (internal in SRM system 1 and SRM system 2, external number range in R/3), e.g. 3100000000 - 3199999999
2- in SRM system 2, fill in current number with (for example) 3159999999 and let empty (or current value) in SRM system 1
3- assign, in each system for your concerned transaction type, number range as internal in SRM and external in R/3.
In this way, you will avoid overlaping in R/3 between PO numbers coming from SRM system 1 and SRM system 2

MDM's Source ECC System Splitting into Two

We are running MDM 5.5 and have a single source ECC system, PR1_400, that serves two divisions (Europe and North America). Our company is going to create a separate ECC system for the European division and leave PR1_400 for NA.
The problem is that all of the data in MDM has key mappings to PR1_400 and the European items will need to become tied to XYZ_400. Has anyone experienced such a change and have recommendations?
Thank you.

Hi Keith
If you haven't installed syndication server - install it
You haven't configured remote systems and inbound/outbound ports in your repository
1) stop repository
2) create two remote systems (EU and AF for example)
3) create inbound/outbound ports for remote systems
4) set "key mapping" parameters in main table to "Yes"
5) load repository
6) Syndicate or save form Data Manager all data to files
7) Create import maps in Import manager for all source files( and save its in repository
8) stop repository
9) go to inbound/outbound ports and select early saved map files for automatically load data
10) start repository
11) put source file to inbound directories
12) start syndication server
13) wait when import process was done
14) load data manager (you see triple records from EU from AF and with empty "edit key mappings" properties)
15) select matching mode and turn matching rules for key fields
16) run matching process
17) merge tree to one record
18) after that one result record had tree remote systems in "edit key mappings" propeties
manually
do step 1-10 if it need
11) stay ro record and load "edit key mappings" propeties
12) push add button select remote system
13) push OK
14) dublicate records
15) do step 12-13 only select another remote system
16) do that steps 11-15 for all records
17) do steps 15-18 but with two identical records
finish

BW linked to two ECC source systems

Hi,
We are planning to create a sceneraio in whih our BW quality (client 350) will be linked to two different ECC clients (550 & 590).
Earlirer 350 was linked to 550 only.
Now the question is while transporting request from BW development (client 310) to BW Quality (350), will it ask the source system??
For which source sytem request will be transported, 550 or 590???
Pls. clear the concept.
Thanks in advance
Shilpi Gupta

Hi Shilpi,
It seems you are bit confused about the connection and the transport.Let me try to add some more points.
Your source system is ECCDEV (540) and the target source system is ECCQUALOTY (590) . Your BW Quality is 350.
BW quality is connected with two source system (590 and 550).
All your BW objects are source system independent other than Transfer rules. So whenver you transport any objects from BW development to Quality (like InfoObjects,InfoSource,InfoCube ,ODS,update rules etc) there is no problem with the source system connection. It just appears in your BW Quality .But your transfer rules is dependent on the source system. So when you transport the transfer rules,you need to make sure that which source system (Qty) should carry that changes i.e.transfer rule mappings.
So you need to maintain this settings in the above mentioned transaction code,even if you use only one source system.
Then only your transport changes will appear in your quality transfer rules.Even though your quality BW system is assigned to two source system ,only one system will carry that transfer rule mappings.Hence this mapping is required for any case.
You can change the mapping anytime (from 590 to 540) using this tcode to get the transfer rule mappings for the other system.
Thanks.

How to connect two BW systems to one ECC system?!?

Hi Experts!
We want to connect our ECC system (P11) to multiple SAP BW systems. Therefore we made a system copy of our productive BW System (P81) and create a new second BW System (T81). When I want to restore to connection to the P11 in the T81, Iu2019ll get the following error message:
u201CDie Verbindung CA wird im Quellsystem P11_001 als Verbindung zum BW T81CLNT001 genutzt.
Soll diese Verbindung im Quellsystem gelöscht werden? Nach erfolgreicher Löschung wird der Anschluss wiederholt.u201C
In English this message means something like that: u201EThe connection CA is used as a connection to the BW T81CLNT001 in the source system. Should this connection be deleted in the source system? This connection can be repeated after successful deletion.u201D
Now I ask myself: How can I connect our new BW System to our ECC System, without destroying the old connection to our productive BW system?!?
Have anyone of you an idea how we can handle this issue?
Thanks in advance!
Regards, Alex

Hi
This happens because of RFC settings duplication as your new BW system is copied from Old one.
First you restore the Production system connection by deleting the existing RFC. But this will delete the new connection you have created ( that is what your dialog message is saying)
Basically , before creating new connection you need to delete some table entries manually , then you can connect both the system to your same source system
Please find the link below where I mentioned the table names from where you need to delete duplicate entries manually.

Connecting multiple ECC Clients on same ECC system to BW system(s)

Hello.
We are considering connecting our Dev BW system to multiple clients on the same Dev ECC system. This connection would be for a limited time. We are wondering what the effect would be on the ECC system after we 'disconnect' our BW system from one of the clients.
Another thing we are considering is to create a seperate BW sandbox system and to connect that to a client on our Dev ECC system. The Dev ECC system will, at the same time, have a connection to a client on our existing Dev BW system. For example, having DEVBWcnlt100 -> DEVECCclnt100 and SNDBWclnt200 -> DEVECCclnt200 where DEVECC is a system and DEVBW and SNDBW are systems of their own. Our Sandbox BW system will have a limited life and at some point be taken down and no longer be a valid source system for the DEVECC system. We are concerned about what the impact would be to the DEV ECC system's client independent data once the Sandbox BW system is disconnected and taken down permenantly. Is 'residual' client independent data something we need to be concerned about? Is having two different BW systems connected to ECC clients on the same ECC systems a 'bad practice'? Any and all comments are welcome as we have not yet acted on our ideas yet.
Thanks very much for whatever comments you might provide,
Geoff.

We are considering connecting our Dev BW system to multiple clients on the same Dev ECC system. This connection would be for a limited time. We are wondering what the effect would be on the ECC system after we 'disconnect' our BW system from one of the clients.
No impact on the BW system. The only thing that you will have to take care of is that any process chains which fetch data from this DEV ECC system should not be put on periodic cycle because after disconnecting the ECC system, these would start failing.
Another thing we are considering is to create a seperate BW sandbox system and to connect that to a client on our Dev ECC system. The Dev ECC system will, at the same time, have a connection to a client on our existing Dev BW system. For example, having DEVBWcnlt100 -> DEVECCclnt100 and SNDBWclnt200 -> DEVECCclnt200 where DEVECC is a system and DEVBW and SNDBW are systems of their own.

We are concerned about what the impact would be to the DEV ECC system's client independent data once the Sandbox BW system is disconnected and taken down permenantly. Is 'residual' client independent data something we need to be concerned about?
Again no impact on ECC system. As for the client connected earlier to sandbox system, just clear all the queues in RSA7, LBWQ
Is having two different BW systems connected to ECC clients on the same ECC systems a 'bad practice'?
No its not at all a bad practice

Extracting Values of a Field from a Database Table in SAP ECC System

Hi,
I downloaded Extracting Values of a Field from a Database Table in SAP ECC System Using MII 12.0
senario from sdn. I'm trying to do that senario in MII 12.05. But I have problem with section 6 in page 7 (you can supply senario from sdn)
"6- Under the loop of Repeater, use action u2018Rowu2019 to append just the string part of the WA which will display only values for field u2018Batchu2019"
I did not find WA elemen in Output element of Repeater_0
How can I create WA element?
Thanks.

Cemil,
Set up a SAP JCo Interface action block. Use the RFC name RFC_READ_TABLE.
In the link editor map the table to "MARA", set RowCount to something small (20 is good sample size) and create an xml transaction property named FIELDS and copy the following into it:
<?xml version="1.0" encoding="UTF-8"?><FIELDS>
      <item>
        <FIELDNAME>MATNR</FIELDNAME>
        <OFFSET/>
        <LENGTH/>
        <TYPE/>
        <FIELDTEXT/>
      </item>
      <item>
        <FIELDNAME>MTART</FIELDNAME>
        <OFFSET/>
        <LENGTH/>
        <TYPE/>
        <FIELDTEXT/>
      </item>
      <item>
        <FIELDNAME>BSTME</FIELDNAME>
        <OFFSET/>
        <LENGTH/>
        <TYPE/>
        <FIELDTEXT/>
      </item>
      <item>
        <FIELDNAME>XCHPF</FIELDNAME>
        <OFFSET/>
        <LENGTH/>
        <TYPE/>
        <FIELDTEXT/>
      </item>
      <item>
        <FIELDNAME>DATAB</FIELDNAME>
        <OFFSET/>
        <LENGTH/>
        <TYPE/>
        <FIELDTEXT/>
      </item>
    </FIELDS>
Then link the Transaction.FIELDS to SAP_JCo_Interface_0.Request{/RFC_READ_TABLE/TABLES/FIELDS}. You may run into problems with two other fields and optionally they can be removed (set link type to remove xml). I usually remove them initially for testing. The two fields are:
SAP_JCo_Interface_0.Request{/RFC_READ_TABLE/INPUT/NO_DATA}
SAP_JCo_Interface_0.Request{/RFC_READ_TABLE/INPUT/DELIMITER} (or you can set this to something like a semicolon,";" or tilda,"~". I find it easier to caclulate position by length, but that is my own idiosyncrasy.)
Once you get this one working, we can explore how to do filtering on the dataset. Your output should be something like this:
<?xml version="1.0" encoding="utf-8"?>
<RFC_READ_TABLE>
<INPUT>
    <DELIMITER />
    <NO_DATA />
    <QUERY_TABLE>MARA</QUERY_TABLE>
    <ROWCOUNT>20</ROWCOUNT>
    <ROWSKIPS>0</ROWSKIPS>

Add a repeater sourced on:
SAP_JCo_Interface_0.Response{/RFC_READ_TABLE/TABLES/DATA/item}
Link your repeater output to a tracer with this:
Repeater_0.Output{/item/WA}
What you will see in each tracer message is a single line of data with all the fields contents concatenated together. You can look up what each field in the string represents by the length of the field as returned in the Response segment of the RFC_READ_TABLE rfc. Then you can parse out the data you are interested in.
Give this a try and let me know how you succeeded.
By the way, I could not find the scenario you referred to. Can you post a link?

Two SNC system and one execution system

Hi Experts
Can there be possibilty of Two snc system to co exist with one execution system ECC?
IF yes can you folks please throw some light on the same?
This situation is arising because:
the Lime table in the existing system has really grown huge and the archiving is not helping becuase there are new records that are added to the system every day which are more than the archiving records
because of this huge data the upgrade is not possible and we are planning for a new setup, now to mitigate the risk we were tryin if two SNC system can coexist with one EEC system.
Now to add to the problem is there are certain business scenarios because of which we need to put in data in lime table every day
so reduction in data input is not possible.
As the data in LIME is only stock of the customer coming every day and if we just transaction data , even if we go away with all the data is not an issue with us as customer reports his existing stock on daily basis to us.
We have even thought of truncating all the tables available in in lime objects in SARA, we are thinking of this becuase system might act erratic when we setup new system and slow try moving few customer from existing to new system. as a pilot.
Supposing if we go ahead with it ,wht could be the issues ?
Thanks for all your help and suggestions
Regards
Manas Malhotra

Hi Manas
Two SNC systems can coexist together.
You need to define seperate Business System Groups,RFC settings,Logical System definition
Also you need to have seperate Identification for your master data, create your own definition in BADI
Example:If you are sending same material XXX to two SCM systems how to diferrentiate ???
Because BADi methods EXIT_/SAPAPO/SAPLCIF_LOC_001 & EXIT_/SAPAPO/SAPLCIF_PROD_001
differentiate when two ERP systems are connected to one SNC system by prefix and sufix, now you need to have your own code to differentiate
Also big time care should be taken in defining the distrubution models (bd64) and even in XI/PI like
Example: we have two TM systems coexisting with one ERP, so we used conditoned based mapping
Itu2019s a condition based mapping.
1) When TransportationRequestSUITERequest/TransportationRequest/ShipToLocation/InternalID = BP1 or BP2 or BP3 u2026 the receiver is I5YCLNT100
2) When TransportationRequestSUITERequest/TransportationRequest/ShipToLocation/InternalID = BP4 or BP5u2026the Receiver is I5XCLNT100.
Also care should be taken on master data/FICO settings which both systems use in common. like using Ztypes instead of using standard one like order type, message type. It should be easy when you troubleshoot back!!!
The inbound message parameters should be taken care w.r.t business needs
Good to have a matrix mapping like what business process coexit in both systems and which doesnot and then try to see what settings need to be tailored???

Cross reference data from 2 different ecc system.

Hi Sdners,
Iam working on a scenario where i have to get data from two different Ecc system,consolidate them and send it back to their respective system.
But some refernce data in both the systems are different and when iam merging data from 2 system i have to maintain either of the reference data.But problem comes when i syndicate it back to ECC ,it cannot accept a new reference data.
Please suggest me some answere how to proceed in such case.
Its urgent.
Points will be rewarded for Genuine answeres.
Thanks in advance,
Regards,
Neethu.

Hi,
First enable keymapping property to YES for the table which you want to do
importing and syndicatig.
Create two remote systems type inbound/outbound .
Import the data from first remote system and map the corresponding fields.
Don't forget to map the remotekey field which is on the destination side.Make clone
of one of the dispaly field and map to the remote key field.
After importing you can see the records from which remote system are imported
using Edit Key Mappings option in DataManager.It shows that remotesystem
name and corresponding remote key.
Do the same for second remote system too.
After merging data in data manager , you can see the merged record and see the
two remote systems names and two remote keys by using Edit Key Mappings
option so the merged record goes back to both remote systems when you syndicate
the records.
Syndicate the data from first remote system by selecting destination properties and
output remote system property under map properties tab as your first remote
system.
Do the mapping for corresponding fields and don't forget to map the value field under
remote key .Then MDM generates remote keys for only records belongs to your
first remote system.You can see this in destination preview.It does n't genarate
remote keys for second remote system.Then check the option Suppress records
without key under map properties tab and execute the syndication.Finally we can
see the accurate records.
Do the same for second remote system too.
Hope it helps
Cheers

Crystal Report connecting Multple ECC systems

Hi,
I am working on crystal where I compare the data between to two diffrent databases(ECC tables). I am using SAP Table, function mudule option to create connection.
I have built a main report against ECC system A and imported a sub report built on ECC system B. Now I see that connection in my main report is overwrting the connection in the sub report. If I change the connection in the subreport with set data source location it changes the connection of both sub report and main report. After I deploy this report to infoview, in cmc I see only one database connection.
Is this a bug or can we have only one connection to ECC system per one crystal report even if it has sub reports?
Thanks

Yes that happens automatically, I just checked the same logic with universes built against oracle data source, I could see two coonections in the CMC. Its like its there is this issue when I am connecting to sap tables directly

Two BW systems - one partition/server. How do you divide the resources?

Hi.
We installed a BW DEV system onto a partition of an IBM p570. Roughly 22 GB RAM allocated and plenty disk. Everything was running smoothely until we decided to install a BW QA system on the same partition. Ever since then, the DEV system has become very unstable and hangs and then crashes on a frequent basis. On inspecting the trace/log files, we can see obvious messages about the system running out of SWAP space and then halting sessions/processes. My understanding of the situation is that, when DEV was installed, it obviously "believed" that the 22 GB of memory was exclusively available to it and, now that QA is trying to run and grab resource, the DEV is somehow complaining that it doesn't have the resource that it believes it SHOULD have (in layman's terms).
My question is, in order to get BOTH the systems running optimally (i.e. DEV and QA), what parameters do I need to change/force in order for each of the systems to believe that it now only has 11 GB of memory available? I can only think of checking memory-related parms in the config tool (heap memory, etc.), the PHYS_MEM_SIZE and j2ee/phy_mem_size in the instance profile and then one or two Oracle specific parameters around DB_CACHE_SIZE and SHARED_POOL_SIZE. There are, however, lots of other parameters, e.g. em* parameters, that I can see in the active list (TU02) that appear to be memory related, but I don't know if it is necessary to change these values, or whether they are dynamic.
The two BW systems are ABAP/JAVA combinations (NW2004s) on AIX 5.3 / Oracle 10.2.0.2.
Thanks in advance!

read SAP note 88416.
I would leave 1GB for OS and provide 21GB for each instance (including Oracle instances)
so basicalyl, size each instance as if you would have about 10GB only available.
