Segment Population Error
A Segment-Population error occurs while running a segment.
java.sql.SQLSyntaxErrorException: ORA-00904: "PC0S"."CUSTOMERID": invalid identifier
Steps to Reproduce
Create a segment, and run it.
The custom data class has an incorrect key column mapped in the general tab of class definition. This was changed by the user during the custom data class creation using the Database Class mappings tool.
The key property on the custom data class must be CustomerID. This property can be mapped to any one database column (of the appropriate type) through the External Mappings on the Class rule.
