How to download Product master data from SAP IS Retail to SAP CRM?

Hi,

I am aware of the settings we are supposed to do while replicating product master data from ECC to SAP CRM through middleware. But I am not sure about this SAP IS Retail system, I have never worked with this system and my current client want to use SAP IS Retail system for Product data( Articles ) and the same they want to replicate to SAP CRM via middleware. So, I want to know if the steps will remain same in the CRM side as we do while downloading data from ECC( SAP MM) or steps will differ? Also, incase the steps will be different then can anyone help me with the required steps?

Thanks,

Sneha
