An issue exists in which "reserved" key words have been used or included in the custom alias property for a downstream system. The reserved words are "Dynamic" and "MBRNAME".

The steps for creating a real-time validation are:

1. Create a custom property to verify that the value input in the custom alias property does not contain the reserved words.

2. Test the custom property.

3. Create a custom Validation with the "Property Equals Value" class.

4. Test the validation.

5. Assign the Validation to a version.
