Release

The Release feature in erm4sn allows you to create, manage, and analyze snapshots of modifications in the ServiceNow dictionary over time. Unlike the Comparison feature, which compares multiple ServiceNow versions or instances, Releases focus on tracking changes in the dictionary within a single instance across different points in time. This helps visualize the evolution of schema modifications, ensuring traceability and consistency.

Add or Modify a Release​

To create or edit a release in erm4sn, follow these steps:

    • Provide a meaningful name for the snapshot that reflects its purpose or the changes it represents (e.g., "Q1 Update" or "Pre-Upgrade Review").

  3. Select the Snapshot Timestamp

    • Choose the exact timestamp when the data was loaded from ServiceNow. This ensures the release corresponds to a specific point in time.

  4. Identify the Designer

    • Enter the name of the team member responsible for creating the snapshot. This field helps maintain accountability and transparency.

    • Once all fields are complete, click Save to store the release.

  7. Delete a Release (if needed)

Releases vs. Comparison Feature​

It’s important to note the distinction between the Release and Comparison features in erm4sn:

  • Releases: Capture and track dictionary modifications within the same instance over time, providing insights into the progression of schema changes.
  • Comparison: Focuses on comparing multiple ServiceNow versions or instances, highlighting differences across environments or upgrades.
