We are going to implement Internet Sales for ERP and I have some questions.
1) Is Product Catalog Mandatory for implementing Internet Sales for ERP / R3?
2) We are already using MDM for catalog and we are not the Product Catalog module in R3. Will there be a problem implementing MDM into ISA? Has anyone implemented ISA with MDM as product catalog?
3) We are planning to make it an extra-net application; what is the best architecture placement of the ISA server? Should we have it in DMZ or outside DMZ. What is the best approach among option a and b?
a) Web Browser (Internet) -- External Firewall -- Webserver + ISA server -- Internal Firewall -- ERP
b) Web Browser (Internet) -- External Firewall -- Webserver -- Internal Firewall -- ISA server + ERP
