SAP CRM 7.0 connected to Legacy system
we have the requirement to connect our SAP CRM system (7.0) - that is a brand-new installation NOT to ECC, but to a legacy system.
We have planned to implement custom interfaces to replicate the masterdatas. Doubt is: can you point out which are the Best Practices / Building Blocks in order to perform the configuration in SAP CRM without being it connected to ECC.
Every reply is greatly appreciated.
