Hi Gurus,

I have a questions about SAP CAR solution. Currently we have SAP ECC - IS Retail and SAP POSDM on BI in landscape.

ECC <-----> POSDM(on BI) <----->PI ---- 3rd Pary POS system.

As per our business scenario we have daily once processed Idocs send to ECC over RFC. And master data replicate from ECC to POSDM on demand based using RSA1 trigger at POSDM

Now we want to migrate ECC to S4Hana Retail and POSDM to SAP CAR. For this case is is mandatory to have SLT between S4 and CAR ? If yes then SLT is bundled license with CAR ?

Kindly help me to understand the proposed landscape. Please note that currently we don't have CRM and BI/BW and we don't have plan for it also.

    Yes, S4HANA tables has to be SLT to CAR for master data check and audit. My understanding is SLT is bundled with CAR.

    Ok I have one more question. To get invoices from 3rd party, CAR will receives the Idocs over PI/PO right ? And the processed Idcos will transfer to S4 Hana over RFC ?

    CAR POSDTA needs to be integrated with POS/eCom application , it can be any middleware, if you have SAP PI/PO then Integrate POS/eCom->SAP PI/PO->CAR POSDTA-> S4 HANA.

    Daily Sales Data from eCom/POS needs to sent SAP PI/PO and and then SAP PI/PO pushes sales data to CAR POSDTA with RFC call.

    Once aggregation is completed in CAR POSDTA then it pushes WPUUMS Idocs to S4 HANA.

    Invoice gets processed with WPUUMS Idocs in SAP.
