If you select the Back out a Journal Entry option, specify the Journal Entry number and year of the transaction you want to correct. GP will then create an entry which is the opposite of the original Journal Entry with a new Journal Entry number to offset the one you want to correct. Post this correcting entry and you're done.
If you choose the Back out a Journal Entry and create a correcting entry option, specify the Journal Entry number and year of the transaction you want to correct. The first entry created reverses your original entry. When you post or save the back out entry, a second entry is created. This is your original entry as a new journal that you can modify as needed. Once you have completed all desired modifications, post the journal entry.
