Description

New fields can be created in Studio without having a custom 'u_' or scope 'x_' prefix. 

Name conflicts may occur if such a custom field exists in a table extending an Out of Box (OOB) table and that field does not have a prefix (e.g. created through Studio as part of a scoped application) and then an OOB field is introduced later during an upgrade.

In this case, the platform may add a field with the same name as that custom field resulting in a situation where there are 2 fields with the same name in the same hierarchy. That leads to inconsistent behavior as previous data saved on the custom field not being accessible/available in UI. 

Steps to Reproduce

Steps to reproduce have to take into account future development as a field with the same name needs to be created on the same table hierarchy before the upgrade.

  • Create a custom field via Studio without a prefix.
  • Upgrade to a version that introduces an OOB a field having the same name on the parent table or an ancestor table.

If after an upgrade or plugin update you experience an unexpected behavior related to a custom field that does not have a custom 'u_' or scoped 'x_' prefix. please validate if an OOB field with the same name has been added on the table hierarchy (parent or ancestor table) and contact ServiceNow Technical Support for further assistance.
