What’s happening?
Customers are experiencing errors when attempting to post Project Invoice Proposals, specifically encountering interunit errors.


Reason:
The interunit error occurs when the system is unable to find the necessary accounts for posting, leading to messages such as "Account number for transaction type Interunit - debit/credit does not exist." This can be due to missing Interunit Debit and Interunit Credit accounts in the setup.


Resolution:
For the interunit error:

  1. Ensure that the Interunit Debit and Interunit Credit accounts are set up correctly in the UAT environment by navigating to General Ledger | Posting Setup | Accounts for automatic transactions.
  2. Verify that the dimensions being used are updated correctly to prevent any dimension differences that could cause interunit accounts to be used for balancing.
