Anyone know the best way to "unlink" an invoice so that we can rebill the original Sales Orders? We would like to change the billing frequency on some Sales Orders. We can't void the invoice as we have "VOID TRANSACTIONS USING REVERSING JOURNALS" as checked in our setup.

You could try setting the quantity on each invoice line to zero units and zero dollars and see if that works. If not, deletion of the invoice is probably your only option.

@Noel B i don't know it's the best idea, but i know if you change the customer on the invoice, it breaks the relationship to the SO. That's like intentionally breaking it though.

I can test, but do you know off hand that if you change it back to the original customer, the link is still broken?

Once it's broken it's broken. I don't know if changing the customer resets the item sublist.

I actually don't know any way to fix the broken link once its broken.

Is bill to customer disabled per NetSuite? On our form it is display type is normal, but we can't edit it.

could be your form or your permission. Editing the customer on the SO has the same result...

Admin access and won't let me change the "entity" field. Could it be a script restricting access?
