Transfer Marketing Plan to R3 Project via middleware

We are setting up the transfer of marketing project (CRM 7.0) to ERP via middleware. The system landscape is completed but the bdocs are still red without any error message. the ERP transfer status in the WEB UI is "in Transfer".

The transfer of the standard campagin CCPG works fine and will be create in the ERP.

Can anyone help on setting up of the status so it can trigger the middleware transfer ?

thanks.
