I have 6 variables in my data set:
patient visit center treat dbp dbp1

Center is a group variable and dbp is a numeric variable.

I want to calculate the mean dbp for each center by creating a new column
that includes observations for the mean dbp of each center without having
to create a new data set. I want to retain all other observations for other
columns.

Really, you could show us some example of your data, and an example of the results you want, so we can truly understand what you are asking for. Without that, we are merely guessing, and possibly wasting evereyone's time.

Here's my guess:

Use PROC SUMMARY with center in the CLASS statement, then merge the results into the original data set.

If that's the answer, great.

If not, DO NOT REPLY that this doesn't work without showing us an exaample of your data and the desired result.
