no eligible events when running the PRC: Generate Intercompany Invoices

Hi,

In the output of the process PRC: Generate Intercompany Invoices appears an exception 'This project has no eligible or events'

I have been reviewing the setup to see if I can find something wrong in the setup and the only thing that I found is that for the Provider Internal Project (VS INTERCO), in the customer options/Inter-Project Billing/Bill Another Project the checkbox 'BILL ANOTHER PROJECT' is disabled and I cannot select the Receiver Contract Project/

- Can this be the cause of the issue?

- How can I make the BILL ANOTHER PROJECT checkbox enabled?

Thanks,
