The business requirement is such that, there is a service ticket raised in CRM ( IC Web Client) and I need to transfer this data from CRM to ECC 6.0. I have been following a document of SAP where the same scenario had been explained where the data is transfered from CRM to mySAP ERP, it says XI should be used for this task.
Now, my doubts are
1. Cant we do the data transfer between these two systems through an IDoc?
2. If we transfer data between the two systems, do we have to create the Products and Software Components?
3. Could you please give me any material you have on this current business requirement on XI 3.0?
