1. Void the affected check.
2. Retain the check as new.
3. Use Tasks, Enter Checks to correct the affected line of time on the check as needed.
   Note: You may need to modify your Time Entry view to add a column for the WC code or WC State in order to correct it. for more information, see article 20542 DocLink: How do I modify my time entry view?
4. Click Process to process the corrected check.
5. Click Manual Check to manually assign a check number of your choosing and the same check date as the original check to the corrected check.
6. Click Accept Check, then click Finish.
7. Click Task, Post Checks to post the corrected check. If needed, you may use the Conditions button and add the condition of Check Number-Equal to-x where x is the check number you assigned to the check in step 5 to only post the corrected check.

Note: Changing the WC Code on the Employee setup or on the Cost Code WC Table will not automatically refresh the WC Code on the time entry line. You will either need to manually enter the new code using Change Unposted Time or you will need to not retain the check as new when voiding and re-enter the time.

See the linked article if you need further instruction on how to properly void the check.
