ECC and HANA

Hi,
I have seen a no. of documents about HANA and BW. HOwever there is not anything available about relation between ECC and HANA.
Will HANA replacing ECC? If notis it interface between ECC and BW as I undertsand (may be wrong) that BW is still going to be there?
Can anyone please explain?
Regards
No.One

HANA 1.0 was release with the view of performgin real-time replication from various SAP and non-SAP sources.
HANA 1.0 SP03 is now available - we see the BW application running on the HANA database. (ECC connected to BW as it is, but the underlying database is HANA)
Going forward, we will see HANA 2.0, where in ECC and BW may share a common HANA database.
As far as HANA being a replacement of ECC is concerned, i think the idea is too far-fetched.
There have been discussino on HANA replacing BW in the long run, but this we do not know.
As of now, there is no replacing BW or ECC.
HANA is being used for real-time replication and as a database for BW.

  • How to connect an non-hana-ewm with an Hana-ECC and vice versa

    Hello,
    for our migration project planning I am wondering how to connect EWM on SAP with ECC on Hana and vice versa.
    As it is, both systems are (productive) on non - hana with actual SAP-Release and have to be migrated.
    The background of my question: we may be not able do the "big bang" thing to migrate ERP ECC607 and EWM (with special Add-Ons) at one point to Hana (DMO) and therefore may need an interim solution. I checked ETL and LTS as "connectors" but they - from my point of view -  are one-way solutions from EWM to ECC/Hana -not bidirectional.I Found some questions concerning the same theme in the net but no solution at all till now..
    How about BODS ? (Didnt work with it yet)
    Best regards,
       Ronald

    Great. So I have to either install OS X, or buy a new mcahine. Can OS X run on a G3 without grinding to a halt?
    By the way, I cannot get the iPod to even mount when connected via firewire. The USB/firewire PCMCIA card does not have drivers for OS 9. I thought that this support was built into OS 9. The USB port works (although the iPod will not mount when connected via USB either). Any ideas?
    Thanks

  • Deploying / Transporting SAP HANA-ECC and BW Solution?

    Is there one centralized deployment guid for SAP  HANA solutions in the SAP ECC and SAP BW environment?
    Please can one of you provide some directions to a centralized guide to move / deploy SAP HANA solutions build in one system to Quality and/or production environment?

    Rama,
    there's a pretty straight forward export/import functionality for moveing models from dev to qa and prod. Please see the SAP HANA Modeling Guide, chapter "Processing Information Objects".
    You can also use CTS+ in conjunction with this functionality.

  • Migrating Backend Database for BW and ECC with HANA

    Hi Guys,
    I have been going through the blogs and its fantastic information but i couldnt find anything related to " how to migrate BW or ECC backend database with HANA DB. As per my information the HANA has its own DB which is called "IMDB", so if we have oracle or SQL server at the back end for BW or ECC , how can we migrate to HANA.
    Plus are there any tools that are available for migration.
    Thanks In Advance.
    Sheikh Hassan Ayub

    First, let's be clear:
    1/ Accordingly to announced SAP plans the ramp-up (restricted shipment) of BW-on-HANA installations will start on the 7th of November 2011.
    2/ There are no firm plans for ECC-on-HANA availability yet - so this is out of scope for current discussion.
    "IMDB" is the name from the past. Now HANA's database is called "HANA database" but you will still find references to "SAP In-memory DB" in documentation etc.
    Migration of BW from let's say Oracle to HANA db will be following standard OS/DB migration process - similar to the way you would migrate Oracle DB to DB2: export of the source and then import to the target server. Exactly the same tools.

  • Mixing ECC and NECC (Non-ECC) RAM Modules

    Hi,
    I have a G5 Dual Core 2.0 with a pair of 512Mb Non-ECC (NECC) RAM installed and I want to upgrade to 3Gb. I'm thinking of getting 2Gb ECC modules and discarding the 1Mb NECC installed. But I came across a phrase in the Apple Manual of my G5 that states "DO NOT MIX ECC and NON-ECC Memory Modules WITHIN A PAIR." Does that mean I can mix ECC and NECC within Memory Banks and NOT within a PAIR? Because in that case I won't have to discard my NECC 1Gb and have a mixed 3Gb Memory!? I'm afraid to actually try it so I would appreciate your insights. Thanks much.
    G5 Dual Core 2.0   Mac OS X (10.4.7)  

    Yes. You can mix ECC and nonECC as long as you don't pair the ECC with the nonECC. The computer will just treat all RAM as nonECC.
    You can keep the original memory as long as the two 512MB DIMMs are always paired with each other.

  • Communication between ECC and CRM

    Hello,
    I am in phase of showing communication between SAP CRM 5.0 and ECC 6.0.
    I am struggling with finding some simple transactions which are common in both, with which I can show correct connectivity between ECC and CRM.
       I need to save some data from CRM and access the same via transaction within ECC, save some data via ECC and access it via CRM. I already established RFC link between ECC and CRM.
    Probably communication between SD module of ECC with CRM.
    Can you please help me out with this, a clue/correct direction will be of very helpful. Basically I want to know, what transaction I can use for same.
    Any help is really appreciated.
    Thanks
    -Vishal

    Hi Glenn,
          I followed all steps in document mentioned above. In the end during execution of transaction I selected appropriate source and destination, when I click start transfer objects, it gets stuck in waiting phase.
    Among those steps I was not able to perform step#10. Creating Subscriptions for OLTP. My ERP is not displaying this option under subscription wizard. Should it be reason for not starting transfer ? I also do not see ERP logon screen when I select transfer.
    My another question is when transfer will complete, where I'll be able to see transferred objects within ERP database ?
    Thanks

  • Same MessageID  from sender(Webservice) --  PI --  ECC and vice versa

    Folks,
    We have a sender and receiver  webserver which has its own monitoring system in it and it tracks messages by means of Message ID which it creates .
    Now this web service when hits PI it sends the message ID in a field in payload.
    The message ID which the webservice sends is now different then which is created in PI as the  message propagates
    The same message ID is created in ECC as we all know .
    Now Our problem is we are  finding it difficult to track messages from webservice Outbound as well as inbound
    If there are 100 messages we have to search on the basis of time only , we cant search on message ID
    My question is can we have a unique message ID throughout the scenario.
    ( i.e webservice -- PI-- ECC and ECC -- PI --Webservice)
    Please  help
    thanks
    Ninad

    Thanks Gouri ,
    In case of webservice sender the webservice sends a message ID in a payload ( they have there own monitoring using there own message ID )
    Being in Support , I get a call that message belonging to  xxxxx message ID has failed. Now when I look in SXMB_MONI
    I see 1000 messages between same sender and receiver.
    I have to check payload and check the said message ID and then find the message , this is Cumbersome
    hope we find some better approach
    Thanks

  • Organization structure in CRM 7.0 from ECC and HR

    Hi,
    We are trying to download Org structures from ECC and HR. (CRM 7.0, HR & R/3 ECC 6.0)
    From HR
    The ALE distribution is set across the systems CRM and HR and I did the PFAL run as per the best practices BB C05. There are about 100,000 Idocs inbound to CRM system and out of which about 15K are in 51 status and the rest are in 53 status.
    Observations:
    The Organization structure from HR is not totally mapped in CRM but only a part of it is displayed in PPOMA_CRM.
    The remaining Org units are found in 'non-related objects' selection.
    All the Idocs in failure are in error "Error in subroutine read_namtb for structure  of infotype  ". When I go to the long text
    Message no. 5-109
    Diagnosis
    An error has occurred in subroutine read_namtb for structure  of infotype .
    Procedure
    Check the entry for infotype  in table T777D (structure, IDoc segment, expanded structure) and the corresponding structures.
    I am not sure which infotype needs to be checked in T777D.
    From ECC
    The CRM - ECC connectivity is set. Downloaded all the required customizing objects successfully. Switched the org model to "enhanced backend integration version " and then followed on to SPRO->CRM->Master Data->Organizational Management->Data transfer->Copy SAP ECC structure and selected all the available R/3 Organization assignments available and then selected the "generate selected lines".
    Observations:
    All the generated org units are in GREEN in SPRO but there are no assignments found in PPOMA_CRM not even in the unrelated objects
    Checked tables HRP1000 and HRP1001 from the CRM Sales org unit IDs (ex: O 5000012) created here and they are not found but the generation is in GREEN.
    I will appreciate any assistance I get here.

  • No connection between ECC and PI

    Hello,
    I have developed proxy to file interface but I am not able to see any data flow between backend ECC and PI systems. I have gone through different blogs and forum threads to troubleshoot... creating RFC destinations, testing through RWB message, SLD configurations, SICF, etc. but I am not able to see any data going out of or into ECC. When I check SXMB_MONI or RWB message monitoring, I don't see any message either failed or success.
    I don't think ECC is connecting to PI. I am able to create proxy in ECC and configure both inbound and outbound proxy but I don't see any data go through ECC. I am able to import RFC and IDocs in Integration Repository. Can anyone suggest what could be the problem and how to resolve it?
    Thank you!

  • Vendor Number Range Conflict SAP ECC and CRM 2007

    I need to load SAP ECC Vendor data from SAP to CRM and have setup most of the configuration as required. However I have an issue, the vendor number range used currently in our SAP system is already in use in our CRM system and has been for some time (for Prospects and Contacts).  What is the best approach to dealing with this issue...
    My initial thought was to see if we could have two different numbers for the same vendor in ECC and SAP CRM
    eg SAP Vendor "50000001" equates to CRM "VEN50000001"
    Is such as approach supported?  Can you point me to the documentation that shows how such an approach could be implemented.  What approaches have others done to address similar issues?
    Thanks in advance
    Eddie
    By the way we are on CRM 2007 sp4

    Hi Eddie,
    SAP Note 1044637 - Customize Vendor Numbers
    Implement the code present in the attachment. You can
    change it according to your own requirements. The example code
    suffixes 'VEND' before the first six digits of the vendor
    number before it is downloaded to CRM.

  • Communication between ECC and SCM via XI

    I am trying to set up the scenario 'Purchase_Order_Processing' between
    ECC and SCM using XI. The SCM content for XI has been loaded into XI
    and this scenario is included in the content.
    We are running the following:
    ECC - Version 5.0 - 640 SP level 12
    XI - Version 3.0 - 640 SP Level 14
    SCM - 4.10 - 640 SP Level 12
    The connectivity between the systems has been set up as described in the configuration guides. On sending an IDOC (basic type ORDERS05) into XI I get the following error message 'Http server code 500 reason Internal Server Errorexplanation Error during parsing of SOAP header'.
    The Error XML is as follows:
    <?xml version="1.0" encoding="UTF-8" standalone="yes" ?>

    Sravya,
    Yes this an IDOC to http scenario. There was no dump at the receiver end. I've found out what was causing the problem - I was using an adapter type of HTTP. It should have been of type 'XI'. I've altered this and it works. Hopefully this will resolve your problem Vinod.

  • Block Demand Depend Interfaces between ECC and SCM

    Hello All.
    Is there a way to block only interfaces of Dependent Demand between ECC and SCM.
    I need to do this because ECC writes over my plan in SCM.
    Thanks and Best Regards

    Hello PrasunM
    For example:
    When you create an Order on finished material, SCM using PP method "3 - Cover Ind. Requ." creates DepReq on raw material.
    SCM using CIF sends PlOrd, PrdOrd and DepReq to ECC. I want send only PlOrd and PrdOrd, DepReq i only need in SCM side.
