I’m trying to post an invoice and keep getting this error. It’s not only one specific invoice it’s all invoices by all users.
If you do Intercompany Transactions, you’ll need to set up your users with at least read permissions to the IC Partners table (#413). If you do not do Intercompany Transactions, then perhaps someone mistakenly turned this feature on. Check out the setup here: Departments/Financial Management/Setup/Intercompany Postings/IC Partners
