Unable to branch a ruleset which has an underscore in the name



Unable to branch a ruleset name which ends with two characters following an underscore (..._XX).

Error Messages

Not Applicable.

Steps to Reproduce

  1. Log in to the application
  2. Create ruleset name like AB_CD_EF
  3. Create a branch and attempt to select this ruleset

Root Cause

An issue in the custom application code or rules.
The ruleset name pattern (AB_CD_EF) matches with the language-specific rulesets which should not be branched.


Here’s the explanation for the reported behavior: 

The IsALocaleRuleSet function identifies a ruleset as language-specific if it fits the pattern of base_xx_yyy_yyy . . .. The base can be any length, the 'xx' is the language and is exactly 2 character, and the 'yyy' is optional language variants which must be at least 3 characters but can occur over and over.
