%% Ambiguity: The document mentions a relation to "PLAN", but no table named "PLAN" exists. It might refer to "reference_PlanScenario" or another table. This needs clarification before adding the relationship.
%% Note: The relationship is mediated through the CompliancePlanLink table. Each SourceApportionment may apply to several AttainmentIds, but each AttainmentId should only have one SourceApportionment.
