Hi @wicky05926088,

could you possibly share some context?

If you mention a reference field, it cannot be string, it is referencing  another table with sys ID (not string) and then the filed shows the display value..

Example: Location, Assignment group, Manager, Department etc. All these are references but if you check their value, it's sys ID stored in these fields

See the example of Location and Department on [sys_user] table:

Please share some more context of your issue or what you want to achieve
