Instead of creating a new journal entry (JE) from scratch, you can copy an existing one that's similar to the one you want to create. After you make the copy, you can edit the details as needed.
For example, every month you create a journal entry for a mortgage payment. The journal includes five detail lines: one for the principal, one for the interest, one for the property tax, one for the insurance, and one for cash. Instead of creating a new journal entry, you can copy last month's journal entry and edit the amounts for the principal and interest.
Everything is copied, including notes and reference fields, except for dates.
To copy a journal entry
Go to Accounting > General Ledger > Journals.
Locate the journal entry you want to copy and open it.
Click the Copy button in the upper right.
The New Journal screen appears. The date fields (Journal Date and Post Month) default to today's date and month.
The detail section is a copy of the original journal, and you can edit it as needed. In this example, we changed the amounts for mortgage principal and interest.
Click Save when you are done.
