Rule Information

• ADaMIG v1.3
• **Rule 41 (AD0041)
• a numeric variable ending in DT, does not have a human readable date format

Describe the problem

1. Query if a variable is numeric
2. Query format associated with variable

Describe the solution
A clear and concise description of how this problem could be solved.

1. e.g name :variable_type operator :"is_numeric" operator applied to determine variable type
2. e.g extract format from supplied data and either compare to a predefined lookup list of formats and/ or provide users the ability to supply additional format (extensible list): name: variable_fmt operator: contains_valid_fmt
   see pbi specifically for adding formats to test data in the rule editor: [https://github.com/Support format variable metadata in test data conformance-rules-editor#145](https://urldefense.com/v3/__

Proposed rule logic

Replace this with an example of how the new solution could be written as a rule
check:
   -name: variable_type:
     operator: is_numeric
  -name: variable_fmt 
    operator: is_valid_format 
or 

     operator: is_valid_date_format (predefined list) and contains
     values:   (extensible user supplied format list>
