To check if reassessment is required, the eligibility and entitlement engine compares the cover period from date of all new decisions to the cover to date of the case. The cover to date of the case is the latest cover period to date for all ILIs, i.e., the output of all processed financial components. According to the sample data, the date up to which the benefit has already been covered is April 30th. If any of the new decisions are before this date, then reassessment is required. The cover period from dates for each of the decisions in Create Virtual Financial Components are March 15th, April 5th, and April 16th, all three of which are before April 30th, and thus reassessment is required.
