      Hi Avijit ,

       

      SLT related transactions will be available only after deploying the DMIS addon in your ECC system .

      Hello Tobias,

      Excellent documentation! However, I would like to mention that a few links such as the security guide and application operations guide are broken or have been updated for HANA SP05. Can you please update the links?

       

      Regards,

      Quick Question Tobias.

       

       

      Do you know if we can schedule the start and stop of replication on a daily basis. I am not referring to scheduling the replication here.

       

       

      My scenario is Source SQL Server DB -> SLT NW System -> HANA.

       

       

      Everyday Source SQL Server gets refreshed and we are manually stopping the replication just after refresh and starting it again. We know this will delete and create triggers which we are fine with. Is there a way we could automate this at all. Please advise.

       

       

      Regards

      Hi Tobias

       

      Great blog. Thanks.

       

      I am interested in the Load Statistics tab.

      What are the tables that feeds this view?

      I would like to replicate these tables to HANA and create a view and dashboard to track the replication status and progress.

      hi Tobias,

       

      We have installed SLT SP9  which supports Oracle DB as target. We could not find any documents for this

       

      can you please help with this - we are replicating data from SAP ECC to oracel db via SLT & we need clue on how to table woudl be replciated in oracle/what structure be created etc.

       

       

      Also any other learnings you are aware of.

       

      Thanks

      Great Overview, thank you!
      Anyhow one question: is there ar more current version of the Overview slides available? This still relates to SP05 and is from 2013.
      A newer version would be great!
      Thank you

      Hi Tobias,

       

      actually I'm a little confused on whether SLT application-based replication from e.g. ERP/Oracle towards Simple Finance meanwhile has been realized .. the info sheet does list it as a given (Application-based Replication Scenarios - Support of Simple Finance) whereas SLT overview presentation still shows it as planned innovation.

       

      Now that DMIS_2011 SP10 was released end of December is above scenario being supported ?

       

      Cheers, Carsten

      Hi Tobias,

       

      Any details on SP10 released - what changes are done in this release?

       

      thanks

      One thing that isn't entirely clear is whether the LT Replication Server is meant for providing NZDT for a DR scenario.  Today we use storage replication/mirroring to keep our DR database in sync. All of the literature suggests moving data from SAP non-HANA or non-SAP environments to an SAP HANA environment.

       

      Can we use SLT to replicate an ECC/CRM/APO/BI environment to an equivalent DR

      landscape?

      Hi Tobias

       

      Very nice blog ! Kudos to you and your team,

      I have gone thru the various links, however, i am unable to find a right document on "S4H- Central Finance (On HEC/AWS cloud) integration with On-Premises ERP thru SLT (for very High Volume, real time Integration with multiple SAP and Non SAP ERP systems)

       

      Can you please suggest

      1. if SLT supports above scenario?

      2. is SLT recommended on Target (S4H on Cloud) or source (ERP on-premises) ?

      3. Is there any technical limitation on Volume of Data or alternatively how to compute SLT sizing in such hybrid scenario?

       

      any response will be highly appreciated.

       

      Thanks

      Thanks Tobias. Nice compilation!

       

      Can you help to find out which target databases are supported?

       

      In the slides I only see HANA as the target database.

       

      We have a Project where we would like to replicate

      Src DB2

      Dest1 DB2

      Dest2 SAP BW

       

      Tanks in advance

      Hi Tobias,

       

      We are loading Material master from ECC to MDG system and we are facing an issue while loading MBEW table. We are getting error as Duplicate secondary index. Source table records are already written to the target table except the 1 record which failed. But in LTRC data transfer window, the status of the table is fluctuating between 'In Process' and 'Failed'. Can you please provide some info on this issue.

       

      Thanks,
