Hi Community,
While building a personal ServiceNow project in my Personal Developer Instance, I spent a lot of time on custom table design, and it had a big impact on everything that followed.
Here are a few lessons that stood out for me:
• Think carefully before extending task — it adds power but also complexity
• Use clear, consistent naming conventions from day one
• Prefer reference fields over Glide Lists for reporting and performance
• Add audit fields early — they become invaluable later
• Keep the table flexible for future extension, not just today’s use case
This was a self-initiated learning project, but these decisions made the solution far easier to maintain and explain later.
Sharing this in case it helps others working on custom tables in ServiceNow.
Question to the community:
What table design decision do you wish you had made differently early on?
