Steps to Reproduce
Merge the branch ruleset to a target ruleset.
Root Cause
The error is displayed by the pzRuleSetNameIsABranch because the pyRequiresRuleSetVersionElement property value contained invalid symbols. This must be 'Rulesetname:Version', however, this function split the rulesetname from the ':' symbol.
In the branch ruleset, the Application Validation is selected. However, on switching to the Ruleset Validation mode, an invalid character is included in the version field.
Additionally, Pega 7.1.9 allows saving rulesets with incorrect values. This is a bug in Pega 7.1.9 and is resolved in later versions.
Resolution
Perform the following local-change:
- Delete the invalid characters manually from the ruleset prerequisite field.
- Switch to Application Validation mode.
- Resave the ruleset form.
