Cleaning Up ServiceNow Numbering Issues with a Reusable Counter Reconciliation Script

Cleaning Up ServiceNow Numbering Issues with a Reusable Counter Reconciliation Script

Numbering issues in ServiceNow can be awkward to diagnose and even harder to fix safely. In most cases, the symptoms are easy to spot: a new Incident, Problem, Change or Catalog Task fails to insert correctly, or users report that a record number already exists. The underlying cause is often

Configuring Multi-Step Approvals in ServiceNow during the Change Assess Stage

Configuring Multi-Step Approvals in ServiceNow during the Change Assess Stage

This article describes how to configure a multi-step approval process for normal changes during the Assess stage in ServiceNow Change Management. The pattern uses a single Change Approval Policy that is called more than once from Workflow Studio, with a policy input controlling which approval decisions are evaluated at each

ServiceNow Australia Upgrade - HAM Impact!

ServiceNow Australia Upgrade - HAM Impact!

During a recent ServiceNow migration to Australia, I noticed that the Source Request Catalog task was not being generated as expected. After investigating, the issue came down to the automation approach being used. In the Australia release, the legacy workflow was no longer triggering the process correctly for Source Request

Building a Simple but Reliable Backup System for a Self-Hosted Ghost Blog

Building a Simple but Reliable Backup System for a Self-Hosted Ghost Blog

When running a self-hosted blog, everything eventually comes down to one question: If the server dies tomorrow, how quickly can the site be restored? In a cloud-managed system, backups are usually handled automatically. But when running a self-hosted setup on a Raspberry Pi, responsibility shifts completely to the person managing

Filtering MRVS Reference Variables Using a Parent Catalog Item Variable

Filtering MRVS Reference Variables Using a Parent Catalog Item Variable

Multi-Row Variable Sets are a powerful way to capture repeatable data in ServiceNow catalog items, but they come with an important limitation that is easy to overlook. Variables inside a Multi-Row Variable Set do not share the same direct variable context as the parent Catalog Item. That means if you

Using the OOTB Product Catalog in the ServiceNow Business Portal

Using the OOTB Product Catalog in the ServiceNow Business Portal

When configuring self-service for customers in ServiceNow, the goal is simple: make it easy for customers to find the right products, understand what is available to them, and submit an order without needing to speak to an agent. The challenge is that the documentation for using the Product Catalog with

Why Using Sys IDs Is Often the Right Choice in ServiceNow

Why Using Sys IDs Is Often the Right Choice in ServiceNow

Within the ServiceNow ecosystem, few topics generate stronger opinions than the use of sys_ids. Many developers and administrators avoid them wherever possible, preferring names, numbers, or human-readable identifiers instead. While readability matters, the blanket avoidance of sys_ids often creates more problems than it solves. Used correctly, sys_ids

Testing ServiceNow IRE with a Simple Script

Testing ServiceNow IRE with a Simple Script

ServiceNow’s Identification and Reconciliation Engine, usually shortened to IRE, is one of the most important parts of a healthy CMDB. It decides whether incoming CI data should create a new record, update an existing one, or be rejected based on identification rules, reconciliation rules, and data source priority. When

How to Activate AI Search for the Business Portal and Allow Cases to Be Searched

How to Activate AI Search for the Business Portal and Allow Cases to Be Searched

When working with AI Search in ServiceNow, the goal is simple: users should be able to search from the Business Portal and find the records they expect. In an ideal world, enabling AI Search on the portal would be enough. In reality, there are several configuration layers that must align

Using Sensitive Topic Filtering with Now Assist for Virtual Agent Without HRSD

Using Sensitive Topic Filtering with Now Assist for Virtual Agent Without HRSD

Using Sensitive Topic Filtering with Now Assist for Virtual Agent Without HRSD When introducing AI into Virtual Agent, the goal is simple: give users faster, smarter answers while still keeping control over what the AI should and should not respond to. In a standard HRSD implementation, ServiceNow provides a more

Understanding OIDs, MIBs, and MID Server MIB Files

Understanding OIDs, MIBs, and MID Server MIB Files

When working with SNMP discovery in ServiceNow, the goal is simple: ensure the MID Server can ask a network device the right questions and understand the answers it receives. In an ideal world, every device would respond using well-known, standard SNMP values. In reality, network devices, appliances, printers, switches, firewalls,

Oh no - an unsupported Authentication Method!

Oh no - an unsupported Authentication Method!

Sometimes an OAuth integration starts with a simple client_id and client_secret. Other times, the provider expects cryptographic signing, JWT assertions, and elliptic curve encryption. Apple Business Manager is one of those integrations. The good news is that once the moving parts are broken down, the architecture becomes much

Solving the Dynamic IP Dilemma: Raspberry Pi, BT Broadband, and GoDaddy DDNS

Solving the Dynamic IP Dilemma: Raspberry Pi, BT Broadband, and GoDaddy DDNS

When hosting a Ghost blog on a Raspberry Pi at home, the goal is simple: ensure the world can always find your server. In a corporate environment, you typically have a static IP address. In a home lab—specifically one running on BT Broadband—you are at the mercy of

Testing External API Connectivity from a ServiceNow MID Server

Testing External API Connectivity from a ServiceNow MID Server

When integrating ServiceNow with external platforms, one of the first questions is usually simple: can ServiceNow actually reach the endpoint? In practice, that question can be more nuanced than it sounds. Is the call being made directly from the ServiceNow instance? Is it routed through a MID Server? Is the
