AR Revenue being transposed overriding Revenue Rule

Would anyone know why Revenue is being transposed and charge to the wrong Dept. The Intercompany Invoice and Trade Revenue are fine, however the AP invoice is being charged to a different Dept # and the Trade Revenue credited with the correct account. It also seems to be happening to a particular Charge account.

Example for Order # 12345 an Intercompany Invioce and Trade Revenue for the Items in question are created as expected. However the AP Charge Account is being charged to 000.0000.xxxx.0000 instead of 000.0000.yyyy.0000, the Trade Revenue is credited to the correct a/c in this case.

Thanks for your input.
