RDS for SAP data migration through IDOC's

Dear Experts

Just now we have installed BODS 4.1 and RDS also installed now. I am in the process of exploring the RDS. I found all the migration objects is available in the form of IDOC's. Now my questions are

  1. How to work on custom IDOC's. Do i need to extensively code on R/3 side to upload the custom fields. Like user exit or BADI for custom fileds
  2. If yes then i would say implementation time through RDS will remain more or less same time.
  3. Through BODS or by RDS migration objects is there any way without coding on ABAP R/3 side, Can we achieve migrating custom fields

Please let me how to achieve above requirements by RDS

Thanks

    Hi Vijay,

    You are right, the standard content of the Rapid Data Migration RDS packages brings the content with the standard IDoc interface for SAP standard only. So custom objects are not pre-built with the package. However, we incorporated the foundation to include custom coding as easy as possible:

    1) IDoc

    We are using the standard interface technology IDoc. IDocs do have an enhancement concept which is described in the online help. There are three main cases and all of them are supported, however two need additional coding:

    • Z-fields: Additional fields in existing tables lead to IDoc segment extensions
      With the IDoc segment versioning concept this is easy to realize without any ABAP coding
    • Z-tables: Additional IDoc segments will be necessary and lead to a new IDoc version
      With the IDoc versioning concept you can easily add Z-segments with leveraging provided user exits
    • Custom business objects:
      You can even create a complete own IDoc message type in Z-namespace for own stuff, leveraging the given ALE layer of the IDoc middleware

    2) Enhancement guide

    With the RDS package we offer an enhancement guide which helps you to modify the jobs and data flows in the SAP Data Services content according to the changes in the target IDoc structure to reflect additional fields and tables. We built it as a step-by-step guide following for a sample IDoc type but will work similarly for any IDoc.

    Best regards,

    Frank Densborn.

    Hi All

    For the custom fields have we have enhance the IDOC segments and also necessary coding has to be placed on the user exit. On the front end BODS side the IDOC has to be called with additional Z segments.

    • Hi Undam,

      In addition to Vijay's correct answer above, you can always start with the standard jobs in DS coming with the RDM content. Even though the show up as IDoc, most of them are using BAPIs already (e.g. the Material Master object due to performance reasons for the Mass Upload BAPI rather the MATMAS IDoc type). So why does it show as IDocs? You can use a so called BAPI/ALE interface (transaction code BDBG) to call asynchronous BAPIs locally on the remote system rather than performing a BAPI call from outside. Why are we doing this? Again, performance reasons. A live BAPI call through the network from outside would keep the connection open all the time until the BAPI is completely posted. By using the BAPI-ALE IDoc interface, we can split into send (the IDoc is send with all the data and stored locally on the SAP system - this is the only time for network traffic) and then process the IDoc processing (which then calls the BAPI locally) in a separate task on the SAP system. This can be done in the background and by leveraging parallel processing to get the best performance.

      Hope this helps!

      Best regards,

      FRANK.
