What must you do after making changes to a manual journal before it can be posted to the general ledger?

After making changes to a manual journal, it is necessary to save it as a draft before it can be posted to the general ledger. This step is crucial because saving a journal as a draft allows you to review and confirm the changes you've made. Drafts act as a temporary state, providing an opportunity to ensure all entries are accurate and complete, and to make any necessary adjustments before finalizing the journal. Once you are satisfied with the draft, you can then proceed to post it to the general ledger.

The other options do not correlate with the necessary actions required before posting a journal. Approval is typically required in workflows involving multiple stakeholders, but it is not a universal requirement for all manual journals. Archiving old journals may be a good practice for keeping records but does not impact the posting of new journals. Deleting unused entries is generally not relevant to the process of finalizing a journal for posting, as it does not directly address the state of the current manual journal you are working on.
