Scenario - BCL with role SAP_TDMS_MASTER dosn't work ?

Hi all

I try to create BCL Scenario i have 3 System one each system is a User.

Solman:    Dialog -> role SAP_TDMS_MASTER

Productiv: Dialog -> role SAP_TDMS_USER

Test:         Dialog -> role SAP_TDMS_USER

Crawler Scenario BC-Debitor

The system told me on the step start Crawler the RFC Sender and Receiver has no Authorization.

Okay i gave to all role SAP_TDMS_MASTER  but also the same Error

If i try with SAP_all it works well but i think these is not the correct way.

Wich role do you have inside ?

Thanks for help
