Product Feature: Batch Processing / PURLs
If Purl Generation fails, then check that all mandatory fields are present in the source data. If missing mandatory fields are found to be the root cause, then make a note of these rows (so that the customer can resupply them with the missing fields filled in) and delete them before re-generating. The Purl Generation should now complete without issue.
