Send a Knowledge Link when Attaching Knowledge


f you’ve worked with ServiceNow much at all, you’re probably familiar with the capability provided to search knowledge from the incident form, and then attach the knowledge article back to the originating incident. This behavior is extremely useful and can be customized if needed. One complaint I’ve heard about this behavior before is that it posts back the entire contents of the knowledge article into the ‘Comments’ field on the incident. The advantage to this setup is that the solution then gets sent directly out to the end user in their email, but it also comes with a disadvantage since the user never actually has to interact with the Knowledge Base or even know that they could have found their solution there.

One way to better promote knowledge use among your end user community (while still providing useful solutions) is to customize this default attach behavior to send a link to the knowledge article rather than the full text in the Incident ‘Comments’ field. In this article, I’ll show you how that can be done!

Modifying the Label of Form Fields With Client Scripts


ere’s a quick tip for a Monday. This post comes in response to a question on the ServiceNow forums asking if it is possible to change the label of a field dynamically based on some record criteria (such as record type). It is possible, and this post will show you how it can be done.

Advanced Reference Qualifier Using a Script Include


eference qualifiers are a powerful tool that every ServiceNow administrator and consultant should have in their tool belt. They allow you to dynamically filter the available options from a reference field. The ServiceNow wiki has some good documentation on this topic so I won’t re-hash that here. What I do want to address is the topic of Advanced Reference Qualifiers…specifically how to leverage a Script Include instead of a global Business Rule to run your qualifier script.

Prevent Circular Relationships in ServiceNow


lmost any database will have situations where a record in a table can relate back to other records in that same table. This happens in ServiceNow in several places and it’s common enough that you may find yourself building additional functionality that works this way. The classic case is the ‘Parent’ field. A good example is the ‘Parent’ field on the ‘Location (cmn_location)’ table. Each location record in ServiceNow can be related to a ‘Parent’ location. This allows you to build a nice hierarchy of locations within your Service-now instance. Unless you work in one of those very rare places that implements a completely flat location structure, this parent-child relationship is critical for representing locations in your system.

This same type of setup is used in other places (such as task tables) where a given record can result in the generation of another record of the same type. You may have scenarios where a change request can be the parent of other change request or where a major incident becomes the parent of other child incidents. In this post, I’ll address the problem of circular relationships that can exist when you’re working with parent-child relationships in ServiceNow.

Advanced ‘getMyGroups’ Function


f you’ve taken a look at the ‘My Groups Work’ module (or maybe a particular security rule or report) you may have noticed that the condition or filter for that record makes a function call to return a list of values to compare against the value in the given field. In the case of the ‘My Groups Work’ module under the ‘Service Desk’ application there is a function called ‘getMyGroups’ that is used to identify task records where the assignment group value is one of the groups for which the current user is a member.

The ‘getMyGroups’ function simply returns an array of group sys_id values for the groups that a user belongs to. I saw a forum posting recently that pointed out (correctly) that the ‘getMyGroups’ function only returns group membership, but doesn’t return groups where the user is listed as the manager. The function also doesn’t attempt to return child groups of the groups where a person is a manager or group member. So, if I am the Director of Operations and I want to see a list of all tasks for the Operations group (which I am a manager of) as well as the sub-groups of that group, I would have to be added specifically to each sub-group to have all of the groups that I am interested in tracking be displayed in the list.

With some help from John Andersen, I’ve created the ‘Advanced getMyGroups’ function. This function is designed to give users a better way to display group membership information.
