Rework Hours?

Does anyone know the difference between Rework in JobOper table vs Rework in LaborDtl table? We have over 500 rows of rework activity against job operations in LaborDtl where rework flag is true. In JobOper, we have just under 400 entries where ActProdRwkHours >0, but only one of those rows has the rework flag set a true. Viewing a job record in JobClosing, we can see all the rework hours, but just the one instance has rework checked.

So why are we no seeing the rework flag set in JobOper?

I just found the difference, the lone activity was defined as a rework activity when the job was setup. The others are reworks entered by the workers on the MES.
