Using Validations in Tables and Headers
Once your validations have been built, you can define how they are used in your tables and headers.
Validations will only run on tables and headers applied to activities that have been created in the new app after 11 February, 2026. They will not run on tables or headers in activities created prior to 11 February, 2026 or activities that are cloned from an activity created prior to this.
To apply validations, go to Site Settings > Logging > Tables or Headers.

Select which validation rule to apply:
If the validation rule you want is not listed, it may be that the validation scope needs to change. See Creating a New Validation for more information.

The result is that when a logger tries to enter the Min2 value before the Min1 value has been logged, they will receive an error message:
