Once you have configured renewal settings at the portfolio level by adding start dates for disbursement periods, indicating on which dates the applicant will be eligible for renewal, renewal opportunities will be generated according to those dates.
The new renewal opportunities will only be generated on the date that has been indicated in the start date field for the disbursement period. So if your start date is 06/01, you should expect to see the new renewal opportunity appear on that date, and not before. In the example below, 3 disbursement dates have been set, and renewal opportunities would be created on March 4, June 3, and October 1.
Keep in mind that if you add a new disbursement period that is in the past, a "previous" renewal opportunity will not be generated.
For example, if on June 1 you add a new disbursement period of 05/01 to an existing portfolio, you will not see a renewal opportunity generate for that new disbursement.
