Priority Date Missing in H1B i797 approval


I have received H1B extension approval for 3 years based on approved i140 EB3. I am currently in 7th year. However, the priority date in this approval is blank. Can any one please explain if this will have any impact in future and do i need to get this corrected somehow?
It does have correct A-number listed.


You will not get priority date on your H1B approval notice. It does not impact anything. You will only see that in I-140 approval.
