I have 2 companies for example Company A and Company B. User 1 has defaulted and allowed only Company A, and User 2 has defaulted and allowed only Company B.

I created & confirmed an invoice to Company A from Company B -> Vendor Bill by this invoice was automatically created in Company A.

I confirmed & paid Vendor Bill from Company A (this Vendor Bill has status Posted & Paid). 

I need the invoice (from Company B) for which this payment was created (from Company A) to also change the status to Paid automatically with Vendor Bill.

Is it possible?

And how can I set it up?

I tried this process on the Ronbot, but the invoice also remained Unpaid.

Thanks in advance for all replies.
