When integrating data from multiple sources into a Data Warehouse schema, you want to check a length constraint that you have imposed on one of the target columns before the rows arrive in the target table. All the rows that do not pass this quality check will have to be isolated in error tables. For this, you have chosen an Integration Knowledge Module (IKM) that supports flow control. You have also chosen the value raue for this parameter to enable this check. At compile time, you see that Oracle Data Integrator (ODI) throws an error and the execution cannot start. What is the reason?
