For a Upgrade assessment, I upgrade Pega 6.3SP1 with NBFS 6.3.1 to the following in ECS labs.
KYC FS 7.13
POB FS 7.12
I logged into application after making necessary changes to All the related application rules to point to ALL the latest framework application rules/rulesets.
When I clicked LANDING PAGE, I received the following error in TRACER .
Failed to find a 'RULE-NAVIGATION' with the name 'REQUIREMENTSEXPLORER' that applies to 'Pega-Landing'. There were 1 rules with this name in the rulebase, but none matched this request. The 1 rules named 'REQUIREMENTSEXPLORER' defined in the rulebase are: 1 related to applies-to class 'Pega-Landing', but were defined in rulesets which are not in your rulesetlist: 'PegaRequirements:01-03-07'.
As the latest version of PegaRequirements in the stack is 07-15, the issue is happening.
