Possible Cause 1: The job costs created by the record you are voiding are posted as part of a T&M billing.

Possible Cause 2: When the T&M invoice was voided, you clicked No to the message, "Do you want to reset 'Billing Status' to Open on the job cost records?"

Possible Cause 3: If on 19.2 and later, the T&M invoice was posted to period 1 and default period is still period 12 prior year.

1. Display the record you need to void.
2. From the Costs menu, Job Costs.
3. Select the first Record# that appears in the window and click [Drill Down]. This opens 6-3 Job Costs.

7. In the data control box in the upper-left of the window, enter the record numbers from step 5 above.
8. Press ENTER.
9. From Edit menu, Void Invoice.
10. Click Yes to the message, "This invoice was created from Time and Materials Billing. (See help topic 'Voiding a Time and Materials Bill' for more information.) Do you want to continue?"
11. Click Yes to the message, "You are about to void this record. Do you want to continue?"
12. Click Yes to the message, "Do you want to reset 'Billing Status' to Open on the job cost records?"

Solution 2:

1. Change the Billing Status of each job cost associated with the record you are trying to void to 1-Open:
   1. Display the record you need to void.
   2. From the Costs menu, Job Costs.
   3. Select the first Record# that appears in the window and click Drill Down. This opens 6-3 Job Costs.
   4. From Billing Status menu, 1-Open.
   5. From File menu, Save.
   6. Repeat steps c.-e. above for each Job Cost fro the record you are trying to void.
2. Create and post a T&M Invoice from the open job costs.
3. Void the T&M Invoice.
   1. Open 3-2 Receivable Invoices/Credits.
   2. Display the invoice you just posted.
   3. From Edit menu, Void Invoice.
   4. Click Yes to the message, "This invoice was created from Time and Materials Billing. (See help topic 'Voiding a Time and Materials Bill' for more information.) Do you want to continue?"
   5. Click Yes to the message, "You are about to void this record. Do you want to continue?"
   6. Click Yes to the message, "Do you want to reset 'Billing Status' to Open on the job cost records?"

You can now void the payroll record or AP invoice

Solution 3:

NOTE: If you do not want to affect the T&M billing and are okay with just affecting the ledger, follow these steps:

1. Create a new job called Adjustments and possibly a new cost code with the same name.
2. Start with the first payroll record that was posted incorrectly. Click the “Go to transaction” button at the bottom.
3. In the ledger transaction, select from the menu, Edit, copy transaction; File, new record; Edit, paste transaction.
4. Swap all the debits and credits only.
5. You might want to add REV to the end of the check# in the Transaction# field.
6. Change the posting period to the wrong period.
7. Save. A job cost screen will pop up where you will enter the new job and cost code with the full amount of the costs as a negative.
8. Save again.
9. Close that screen and on the 5-2-2 Payroll Records screen, click Go to Transaction again and follow step 3.
10. The posting period should be the correct one.
11. Save and put in the same job and cost code and save again. The amount will be positive.
12. Do this for every payroll record that is posted in the wrong period.
