Dear Chathura and Pamod, Unfortunately, evaluating indicators using what would have been the latest value within every enrollment at a given time is not supported. We could make a program indicator that does the base calculation you want, but it will currently only reflect the disease situation as of the time of aggregation.
Please feel free to write up a JIRA improvement suggestion to support this.
