Auto Numbering for extensible table

[rev3]

Hello community,

I have an OOB table which is extensible. I am trying to enable Auto numbering for this OOB table using Managing Record Numbering - ServiceNow Wiki . The list view shows all the records from the child tables as well.

When i setup auto numbering for this table, it is applied to the records which extended from this table. Can we avoid this to happen?

I want to auto number only the records of that table but not child table records.

Thank You

Sounds like you are looking to leverage the Dictionary overrides so that extended table does not have the same default value on number. This way you can set if the number is going to be set or not on that extended table.

Dictionary Overrides - ServiceNow Wiki

Hi Jake,

Thank for your response. Yes may be a dictionary override will work. I have looked at these Dictionary Attributes - ServiceNow Wiki   but could not find an appropriate one for my requirement. I am sure there might be some other attributes that i can use and are not available in wiki. Would you mind sharing it here.

Also, Can we avoid number gaps with this configuration?

Thank You

To prevent number gaps there is a property to set here: Managing Record Numbering - ServiceNow Wiki by setting Assign a task number only upon insert (prevents unused numbers) to true

I believe it is not an attribute, but would simply be setting an override to say default value = '' on the child tables. In most cases this field should be populated and what I would also recommend is setting a net Number maintenance on the child tables to track a different set of numbers to manage each table.

Hi Jake,

Number field is a single field on the parent table and extends to the child table. In other words the number filed on the child tables is the same on the parent table. So if i am changing the default value then the auto numbering is not populating for my parent table as well.

Thank You
