Dear platform experts,
We all know customizations are an unavoidable feature of ServiceNow, when it comes to real-time customer instances.
If we have a use case wherein there is a task to capture the customizations on a given instance, can someone elaborate on all the possible ways of tracing it?
Some of the known ones are:
- Visit the list of tables (sys_db_object) and check for custom tables (starts with u_)
- Visit the attribute or column list of base tables (cmdb_ci, task and extended tables) or base process tables (incident, etc.) and check for custom attributes in it (starts with u_)
- Check for custom applications (sys_app.LIST)
Where else can I trace customizations? Along with your suggestions kindly suggest the shortcuts or navigations on the instance where to find them.
I hope this post does help many other looking for this info.
Regards,
Anish

Hi there,
With Washington DC "sys_metadata_customization" was added, which gives a nice overview. I also like having a look at "sys_update_xml".
There's absolutely NO need to go into separate things like Business Rules, Client Script, Workflows, etc.. The above I mentioned will provide you almost everything. What not? When its not captured as Customer update / not captured in an Update Set / when its treated as data.
Kind regards,

And when performing Instance Scan checks, I use this piece of scripting to identify if something is custom:
SncAppFiles.hasCustomerUpdate(current)
