Your data contains

Srv_0A,xxxxxxxxx,,xxxxxxxxxxx
Srv_0A,,,
Srv_0A,,,xxxxxxxxxxxxxx
[download]

Should that be

Srv_0A,xxxxxxxxx,,xxxxxxxxxxx
Srv_0A,,,
Srv_0A,,xxxxxxxxxxxxxx,
[download]

If so,

use strict;
use warnings;

my %data;

while (<DATA>) {
   s/^\s+//;
   s/\s+$//;

   my @fields = split(/\s*,\s*/);

   my $server = shift(@fields);
   $data{$server} ||= ['', '', ''];

   # Merge data.
   foreach (0..$#fields) {
      $data{$server}[$_] = $fields[$_]
         if length $fields[$_];
   }
}

print(join(',', $_, @{$data{$_}}), "\n")
   foreach keys(%data);

__DATA__
Srv_0A,Axxxxxxxx,,Bxxxxxxxxxx
Srv_0A,,,
Srv_0G,,,
Srv_0B,Cxxxxxxxxx,,Dxxxxxxxx
Srv_0A,,Exxxxxxxxxxxxx,
Srv_0G,Fxxxxxxxxxx,Gxxxxxxxxxxxxx,
Srv_0B,,Hxxxxxxxxxxxxx,

If not, how do you merge the two Commission Dates?

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
