Hi Lisa,
This sounds related to P21 Enterprise. I will create an Enterprise Service Desk ticket for you to track this question.
Kind regards,
Matt
I am interested in utilizing P21’s Custom Terminology feature to store metadata about our company specific CT standards. As is common in the industry, I’ve created a custom codelist which is a subset of the NCI NY codelist to store just “Y” values, and I’ve named it NY_Y. When this is uploaded to P21, the MD0102 rule (Codelist ID value cannot start with a number and cannot include any special characters.) fires. Why is this the case? Underscore characters in codelist names has never been an issue in Defines.
