Info – These informal messages provide information about what version of the engine and platform you are operating when you run the validation. For example, the message may say how many errors were noted and how long it took to run the validation.
Warning – The “red flag” messages from the engine display a list of items that are problematic. However, these warnings do not prevent the build from continuing. The warnings are important because they are issues that you should fix before finalizing your master schedule and loading students into it.
Error – These messages are validation errors that you must correct in order for the engine to run the build. Many errors are related to one another, and if you correct one error or make the erroneous value valid, you will have corrected other errors as well. Run the validation often while fixing errors. Validation will remove the error messages for the errors you corrected and present a current list of errors. Continue to run the validation until the results are error-free.
