I am creating intercompany transactions, but when I retrieve the transactions using the inbound Transaction task, the transactions are view only – they cannot be edited. I am sure in previous implementations the receiver can edit these transactions to provide their own distributions. The transactions are not set for manual approval so they should just go straight through. They can be processed all the way through to AP and AR if the receiver distribution is completed when the batch is created or edited as an outbound transaction. Am I doing something stupid?
