The validate evidence changes screen allows a user to validate evidence changes for an evidence type. It is a pre-test of the apply evidence changes maintenance function for a specific evidence type. As evidence changes can be applied across any number of evidence types at once, it can be difficult for a user to find and correct all errors that have occurred. Pre-testing allows a user to test the evidence changes for just one evidence type and correct these changes before actually apply them. This screen is accessible from all main evidence screens (from in-edit evidence, active evidence, dashboard, evidenceFlow).
