IPC in SAP ECommerce for mySAP ERP

Dear Expert

I'm trying to configure the following scenario: IPC in SAP ECommerce for mySAP ERP.

We have just upgraded our CRM system from 4.0 to 6.0. The component SAP_AP is available in CRM.

Our ERP backgroung is SAP ECC 5.0.

When I execute the report to initialise database in CRM, I get the following error: Initialisation of configuration database stopped. I don't know what's wrong.

In the SAP ECC 5.0, the component SAP_AP has not been installed. Is it nornal? Could it be why the initialisation is not working?

Thanks in advance

Stephanie
