Posting error after live posting

Hi SAP Guru

I am facing error in Posting

In my client they have updated the cost center wrongly maintained for one employee and they have generated the payroll and made the simulation document but they did not find any error in the Doc so they made live posting for all the employee after that the doc show Incorrect documents.

When I check the doc the cost center is not matching the business area so i told them to change the cost center and generate the payroll and make the posting.

When I generated the payroll for that particular employee I am getting the error Perno 00009473: New payroll run not permitted: seqno 00001 posted with post

Due to one employee i am not able go for posting of other employee

This i facing the new type of error

Plz I needed help today I want to sort this ASAP

With Regards
