Extended Classic Scenario - how does the integration work ?

Posted on Nov 22, 2005 at 12:08 PM 19 Views

Hi,

Apologies for asking a basic question, but we are looking at requirements for integrating SRM with R/3 using the extended classic scenario and I need to understand how the integration actually works ? How is the data transferred between the 2 systems ? Does it use BADI's, idocs etc ?

Many thanks,

fiona

    Hi Fiona,

    In the extended classic scenario, you can transfer Purch. Requisitions from R/3 to your SRM via qRFCs, do the sourcing in SRM, create a local SRM PO and transfer this purchase order to your R/3 with an RFC - BAPI call. (for example the BAPI_PO_CREATE1) Technically there is a so called Plug-in in your backend where the mapping from the SRM-PO to the BAPI structures is done. After this, the BAPI is called in the R/3.

    In the extended classic scenario, the SRM is the leading system. So in the R/3 you will only have a copy of the PO which can not be changed.

    Best regards,

    Olaf

      Fiona,

      Concerning GR & Invoices, the updates are sent to R/3 through ALE/IDOC.

      Concerning Materials, you can incorporate MAterial numbers in the catalog, without replication locally the materials (If you use CCM 2.0, a product catalog can be directly from MM Material master, to enrich Supplier data).

      To avoid local material check, in the catalog link customizing point put the corresponding flag, and fill in a logical system (do not put the local system, or the SRM will continue to check local Material master).

      Best regards.

    Hi,

    The process in the extended classic scenario is:

    1-SC created locally

    2-SC Workflow approval

    3-Local PO creation (if the PO is incomplete, it has to be completed manually by a purchaser user)

    4-PO edition (print, mail, XML and/or fax)

    5-PO transfer in R/3 (BAPI RFC Call) (the created PO cannot be modified in R/3)

    For GR and invoices, they may be created in SRM, then they are transfered through ALE in R/3.

    You've got BADIs in the system for all these documents creations, check,...

    Regards.

    Vadim
