Does this course cover any considerations when you have a domain separated instance?

This course unfortunately does not cover domain separation.

There is a complete 3-day class on this topic. For details, please visit: https://www.servicenow.com/services/training-and-certification/domain-separation.html

Hi, I'm Venky Ramaiah, ServiceNow Sys Admin from London, UK.

I've worked in IT for over 20 years with a Technical Background in Microsoft DotNet and SQL.
For the last 4 years i am being involved with the ServiceNow Development and Support side of things.
I am bit excited and curious to dig in more deeper into the Snow World.

[Marie Sansom]

Hi I am Marie. Here from New Orleans. Just got into ServiceNow. Have been working with computers since before dial-up. I have been many things in life, not the least of which is wife of an Airmen/Firefighter/Medic, Mother of 5 boys, and Cosmetologist. I am not quite at ground zero but like level 2. Looking forward to learning more and expanding my horizon and knowledge base. I love learning! Favorite movie is GOONIES!!! Hands down the best 😉

[sebastian_g_snc]

You have all reasons to be excited 😄 ServiceNow is a great platform.

[Shawn1]

Why when publishing an app for my instances does the pop up say publishing to ServiceNow Store instead of My Application Repository?

[Sre_ko Su_njevi]

Hi All,

 great to meet you all.

[ServiceNowSteve]

Good Afternoon All,

My name is Steve Munsell and I work for Trinity Services Group a division of TKC Holdings. I have been working with ServiceNow for a little under a year and in that time I have gotten my CSA training and learned a lot about ServiceNow but I feel like there is so much more to learn and more specifically a more focused way to approach learning the ins and outs of ServiceNow.

My hope with this class is that I can focus my app development skills to include best practices, code maintenance and so on while learning some new tools I may not yet know of.

[sebastian_g_snc]

There was a question, how to create a module link directly to a VTB:

a) create your VTB
b) click on the little "i" and you will find a link there under "Share"
c) use this link in your module - just remove everything from the beginning of the url to the / after ".com"

Hi, Bob! Unfortunately, I left my sword in Houston so we will have to coexist this week.

[Zachary6]

Hello, my name is Zach
I am new to service now - but have 4/5 years of Development with .NET && SQL.
I work for HR within the government and we are in the process of moving our Applications over to ServiceNOW.

I am here to learn and see how we can make this platform work for us, and begin integration over our current environment.

Personally - while not working, I spend all my free time playing computer games and drinking Gin.
Well, too be honest. Gin and working have no correlation 🙂

Once the application in Studio is committed to Git, the checksum.txt file in Github changes. What is the value and purpose of the checksum.txt file?

[Philip Lee2]

When making a commit, is the list of "Changed Files" based on..

Items changed in the current/active session OR Items changed vs. the source?

[Philip Lee2]

Is the # of committed files based on items change in my current session or is this an active comparison against the source?

[sebastian_g_snc]

First:Do not modify the file.

The checksum is being used to verify the integrity of the application.

[Philip Lee2]

Is the 'confirm' feedback message used out-of-the-box anywhere?

[Austen Harriso1]

In the form designer, I was able to add a field (Requested for) and change it's database name from "u_..." to "requested_for" (w/o the u_ prefix). I was curious why the "u_" was able to be removed, as I was under the assumption that all custom fields in SN had that prefix.

Answer provided in class: Since the whole scoped app can be considered "custom", removing the "u_" prefix is allowed. It still appears as though it's a requirement for all Global tables (to avoid any potential naming issue with future out of box fields added)

[sebastian_g_snc]

you will see that the fully qualified name of your field is actually x_[companyID]_[appname + tablename].[fieldname] .
So since that field is in a scoped app table, it is clear that it must be a custom object.

u_ is found in global 

x_ is found in scopes

[Austen Harriso1]

Great answer, thanks Sebastian!

[melinda_owen]

My name is Melinda and I'm from Cardinal Innovations Healthcare. I'm a Sys Admin and we just recently implemented ServiceNow in my company.

I know how to code, my expectation is mainly to see some best practices for developing inside ServiceNow.

Fun fact: I'm a huge gamer and love comics.

[melinda_owen]

Do you know why when attempting to create the application earlier in class for 3.1, why I'd get an error "vendor key not found"? I've searched Community inititally and usually people get "vendor key not owned" or such.

[User659883]

Hi.  Has anyone looked at lab 4.4?  When writing the client script for the Set Loaner Item Type the script uses g_form.getReference.  I always thought it was bad practice to use getReference and GlideRecords (even with a callback function.)  I thought that it was preferred to use GlideAjax and Script Include?  This is a little more complicated, but returns only the field you require rather than the complete record.  This could have a performance benefit where the code is run often.  Has anyone else heard this?

[ServiceNowSteve]

Anybody remember the URL that gave us our instance passwords?

[User659883]

Don't remember but maybe it's in your browser history?

[User659883]

pctt2018b-test-001-instructor.lab.service-now.com I think was where we entered our name and email address to first get an instance, I think the password was displayed after this

[sebastian_g_snc]

Hi Peter,

your explanation about the difference between both ways of retrieving data from the server is perfectly correct.
However, the use of getReference is not "bad practice" - since it is using a callback function. Bad practice would be to use it without one.

One could say, it is not the leanest way, but the easiest to implement.

[sebastian_g_snc]

Steve, I will look it up for you...come find me before the class. I will be there around 7:30.

[sebastian_g_snc]

If you have wondered, why the CI search on the "Create New" (Loaner Request) in your mobile app is not returning any results: here is the solution: just create a so-called "Document Title" in Module "Table Title" as described in this article:

[User659883]

Hi.  Is there a way to export our application (like an update set), so we can take it away with us, and apply to our own sub-prod instance?

[scottcoen]

The beauty of linking to an external source control (git, gitlabs, bitbucket....) makes that easy.  In whatever instance you want to import the app into, go to studio and in the app selector window you should see a import from source control option, choose that and enter in the configuration details to your repo (url to project, creds) and you should be good to go.

[sebastian_g_snc]

Hi Peter,

you have to distinguish between just moving a dev version of the app over to an other instance and publishing the app: you could use Git and pull the app to a different instance as scottcoen described. This will give you the development version of the app. This is not publishing.

Publishing has to be done via the App Repository OR you can publish into an Update set! See screenshot - it is a related link on the Application's form:

[taylor_comstock]

There is a related link in the application record to publish the app to an update set, as well. 

[That Phil Guy]

For those in my session, I fully intend to demo this. Let me know!

[That Phil Guy]

"HOLD IT!"

[User659883]

Thank you

[User659883]

Thanks

[User659883]

Thanks.  I've tested this out on my dev instance (community dev, not training dev) and this works perfectly.

[taylor_comstock]

Awesome!

[jnovack]

Taylor,

Marketing stopped by, asked if you could use the new "seasick crocodile" green for your call-out squares.  They are phasing out the red.

Additionally, if you could just photoshop your profile picture so you can be wearing a green shirt, they would be grateful.
