Data Replication between SAP backends and SAP Customer Activity Repository

Dear retail community,

If your leading system is an SAP backend system, you can use the data replication framework (DRF) to replicate data from SAP backend to the Demand Data Foundation (DDF) module in SAP Customer Activity Repository.

In addition some objects (e.g. tables) are replicated via System Landscape Transfer (SLT from SAP ERP to SAP CAR. This SLT transfer is a database level replication and hence very fast.

While I am no dev expert I found some useful links that may help you in your SAP CAR and SAP Retail omnichannel projects:

      Is it mandatory to set up data replication between SAP ERP/S4HANA and SAP CAR? In other words can we implement SAP CAR without SAP ERP/S4HANA or with an old SAP ERP ECC 6.04? If we can do it without a SAP ERP system, which SAP CAR modules/functions can we use ?

      If it's mandatory to have a SAP ERP system, do we need to have the SAP retail (add-on) ?


      Thanks for your response !

      Hi Kevin,

      SAP CAR is designed to run in parallel to a SAP Retail system. All SAP CAR functionality is based on ORDERS of any kind. POS documents, SD orders, hybris orders, any orders.

      POS processing is done using article master data, stores, sales org data, product hierarchy and merchandise groups, customers/consumers, promotions, prices, ….

      Planning and forecasts are done based on historic orders.

      All this prerequisite data has to be replicated via DDF and SLT (best) from a connected SAP Retail system, either SAP Retail or SAP S/4HANA.

      There is an option to connect a SAP ERP (non Retail) system to it, but – to my knowledge – there are limitations. It is even possible to run SAP CAR with 3rd party backends, see integration details here.
