How to identify the fields from OOB in a Custom Table

[SAS21]

From the Custom table how to identify the fields that are extended from OOB table ? 

[siva krishna M2]

Hello @SAS21 ,

Usually the custom fields will be created with prefix as "u_" in column name where as ootb extended fields don't have prefix "u_" in their column name

you can see the field "table" in the dictionary entry of those fields so that you can find from which extended table this fields are coming from
