NAV - Intercompany sending AR to standard AR account instead of Partner-Specific AR account

The Partner-specific AR account defined in the Intercompany Partner Setups only apply to transactions being auto-created from the inbox.
Regular Sales transactions will use the posting group on the customer.

Solution:

• Create a separate customer account for your intercompany-specific customer transactions (to separate real sales that may need to go to the actual receivables account)
• Create a specific posting group to send the accounts for this customer to the intercompany-specific receivables account
