We are  trying to create test the MCPR flow in APPS10 version. 

Trying to send an invoice from company 105 to 155 for time booking. 
We have the customer and supplier records as below,

 

When trying to create the invoice from ‘Multi-Company External Supplier Invoice’ window gets the below error. 

 

If I remove the our ID records from the supplier. It creates the invoice. This works if remove the connection from customer side as well. 

 

Anyone has  reason and solution for this issue?
