A hard-coded sys_id in scripts is a common issue in ServiceNow that can significantly reduce the flexibility and maintainability of your customizations. These hard-coded references can complicate updates and migrations by tying scripts to specific record identifiers, which may differ across various environments, such as development, testing, and production.
Resolution Steps:
Create and Use System Properties:
For each hard-coded ID, create a corresponding system property in ServiceNow. This allows the ID to be managed centrally and adjusted without modifying the script directly.
Update the script to retrieve the ID dynamically using the gs.getProperty() method. This ensures that the script adapts seamlessly across different environments.
Test Changes Across Environments:
After making changes, thoroughly test the scripts in different environments to ensure they perform correctly without the hard-coded values.
Before:
After:
By removing hard-coded IDs and utilizing system properties, you enhance the robustness, flexibility, and maintainability of your ServiceNow applications, ensuring smoother updates and migrations.
