Hi All,
Sorry for your inconvenience.
I have found the answer from Online Doc.

SAS Online Doc:
Default summaries are produced with the BREAK statement, the RBREAK
statement, or the BREAK window. You can use default summaries to
visually separate parts of the report, to summarize information for
numeric variables, or both. Options provide some control over the
appearance of the break lines, but if you choose to summarize numeric
variables, then you have no control over the content and the placement
of the summary information. (A break line that summarizes information
is a summary line.)

Customized summaries are produced in a compute block. You can control
both the appearance and content of a customized summary, but you must
write the code to do so.
