Question on Equipment time entry implications to Finance

We have a question on the following;

Using Equipment Time entry P12110, which uses AAI  FTD for debits and FTC for the credit side of the journal.

When doing an add you enter the B/U

Which in this case is 4125, enter the equipment number, billing code, hours, and we're  attaching a work order W 14412767.

The work order is a maintenance work order against equipment number 2504202, the equipment number is attached to B/U 4125 and garage that is doing the work is branch 4128 or it could be 4118.

When I complete the add the journal, created both debit and credit is attached to 4125.xxxx and 4125.xxxx.
