We are using course copies on SIS. But i would like to validate if there is a course that matches the TEMPLATE_COURSE_KEY using a custom script on the header.
Is this possible?
What do you mean by "validate", and what do you want to happen if the TEMPLATE_COURSE_KEY course doesn't exist?
If you want it to skip the record if the template course doesn't exist, I think you can just look under Field Mapping and set the "Invalid Data Rule" to "Skip the record" on the Source Course Copy Key/Template Course Key field.
