Hi!  Hours/costs are posted to jobs when you final compute payroll.

Since you don't do payroll, you will need to go to the job costs that were created when you saved the entry, and on the lower tab under Employee/Vendor, you can enter as much as you need: Employee number, pay type and hours. However, you can't enter the gross wage so if that's all you need, just save when done.

if you want hours you have to post through payroll, i usually do it as a clearing kind of entry where there's value. 

Otherwise you need to go into the job cost entries and adjust the hours
