Supported project types in BPB Tool

Hello Experts,

i would like to use the BPB tool for editing the process structure of my template project.

I dont know why but if I create a template type project it is not listed under Open existing business blueprint list?

Is this type of project supported?

I am using the SP03 version of the tool and 7.1 SolMan SP08.

Any other functions of the tool is working fine.

Can you please give some hints about this?

Kind regards,

Otto
