Document posted without Profit Center

I am working on 4.6 server. Here user posted some Financial GL documents without Cost Center and Profit Center.

Now the issue is,

While running KE5T transaction code, system is showing some differences in two particular GL a/c.

One GL is with PL group and another is from BS (As) group

Now I want to add Profit Center in such documents which are already posted in system.

Please reply Urgently.

Thanks.
