disconnect parent from sub customer
We have a sub-customer that is under the wrong parent company. When we try and change this it says "You cannot change who this customer bills with because there are invoices for the parent that include charges for this customer, or there are payments from the parent that pay off invoices for this customer. Delete all payments or invoices to this customer's parent which link to this customer." How can I find the linked invoice or payment? Is there an easy way to do that, we have hundreds of transactions to go through. Or is there a different workaround to get the sub-customer under a different parent company?
Thank you
