In the last video we talked
at length about adding New Versions, so
what I'd like to do right now is just kind of go over how to
look at the different Versions. And, first
of all, let me go ahead and start by creating a New Version
of this Tank over here. I've got a Storage Tank,
and let's pretend that we've got a new Product that we're going to put in
as of today. So what I'll do is I'll first
create a New Version. So, I'll choose Create Version.
It's going to have this Effective Date.
Actually, before I do that, let's just look at Before and After.
Here we go. We've got Version1, Revision1.
So we haven't really made any significant changes here.
I'll go into Storage Tank.
Right-click Create a Version,
as of right now. That's going to be the Current Time.
Of course, you can browse for a time as well. You can a comment.

Now we've got a New Version. So, this Version
would be presumably something that has a,
something significantly different. So let's say you've changed
from one Product to this Product right here.
We'll go ahead and store that in. And the
way to verify that this has now been stored
in two different places, you know, as both the
original and the new version, is to go into this
tab here called Version, and you can see the
Option here called Show History. Now, I, I actually
could see from the User Interface over here that there
was some history to show. So you look at the little icon
there. Now it has a little clock on it. The little clock indicates
that we've got more than one version of
this Element. So, if I choose Show
History, we can see all the different Versions, and
if I select this, take a look at the
Product. It's HC1500. Take a look at the previous
one. It's BCS1700. By the way, anybody want to
guess what January 1, 1970
at midnight stands for? Well, that's, that's
kind of the Zero Time Mark for PI Systems.
It's basically since the beginning of
when we were counting Time. So whenever you see this
January 1, 1970, it basically means that nobody
has made any changes to this, and that's just the original
effective date. So, from the beginning
of PI Time up until
this point in Time right there, then the Product was BCS1717.
Once we got to that Version the Product
had changed. Now, if you've got --
and we may look at this and say, hey, hold on a second. I've got dozens and dozens of Attributes.
Do I have to look through the whole thing and
compare like that? Well, no. If you hold down Control and select
both of them at once, what you'll see
is will we highlight where there is a
Product, or excuse me, where there is a
change. So, in this case we say Product Value
and then we say it was this.
So, we're highlighting what the differences are between the two Versions
right there. I'd like to point out that, of course, it's going to
show changes going back historically
to all of these items except, of course, if you've got References to
PI Tags. Remember, that's the Value of a PI Tag. If
we make a change to that, that's not something that's going to be stored
with the Version. But, if you notice, this
right here, this Product, that's not a Configuration Item
like these are. These indicate, you know, these will
increment the Revision. This is not a Configuration Item,
but it's still an Attribute of that AF
Element, so we do historize that. And, of course, we
will historize these as well.
So let's say, for example, we change the height.
Kind of far-fetched, but let's say this is now, we realize that's
9 meters. I'll go ahead and check this in.
See that's something else, that when we take a look at the
different Revisions by showing the History
we'll see that show up as well. So, I'll go ahead and select the two.
And so, at every instance in which
there's a difference, you're going to see that highlighted. So the
Value is now nine. The Value was 10, etc.
And the Product Change as well. So as you can see we're historizing
that through this Versions mechanism.
Now, if at some point, you decide that you've got an Element that
really is no longer going to be
useful to people -- in, in other words it's obsolete --
you can simply specify an obsolete date
and then, as long as your query date is before that
obsolete date, you will see the Value once the query
date is after the obsolete date then
at that point we won't see it any more. So, it, it just simply doesn't
appear in the AF Search Results. So, for example, I'm going to
say back on the 1st of October, that was the
obsolete date for this particular
AF Element here. Once I go ahead and check that
in -- well, if you notice
we don't see it anymore. And the reason we don't see it is
because our query date is taking the Default,
which is the current time. So we've effectively
made that disappear from any of the AF Clients
that would be searching for displaying that
AF Element. Now, to go back and look at that again, we'd have to change
the query date. We're going to do that in the next video.
