Here's a scenario that some users might encounter when working with rulesets in Pega 7.

Scenario:

I am trying to add a ruleset as a prerequisite, but have received the following error:

This record has 1 Error in 1 place

pyRuleSetList:** RuleSet "Your-Ruleset:1-10" has a bad format

Solution:

This is not a problem with the referenced ruleset, rather, it is a validation error. A ruleset and version needs to be in the following format: 

<RulesetName>:##-## or <RulesetName>:##-##-## 

(with every single # being a number [0-9].)

An example of when this would occur is if you are trying to add version 7-13, when you should instead by adding 07-13.
