I'm working on an E-Commerce b2b R/3 installation and am getting the following error: The shoplist read from buffer is empty. I have double checked all XCM settings in the xcm config, shopadmin config, and isauseradm config. All jco's are connecting successfully. I have created a product catalog in the ECC system, have a customer created, contact person created, and attached the contact person number to my user ID in SU01. Before attaching my user ID to a contact person I was not able to log into E-commerce at all. Now that I log in, I see the errors about the shoplist. Is there any config I'm missing or other things I should check?
