The reserve migration report is a report for tracking changes in the PRMS reserve class, category, and subcategory between two or more reserve reporting periods using the PRMS qualifier.This is done in a single database with each reporting period set up as separate scenarios and selecting multiscenario run. See the example setup below.

PRMS related sorts are incompatible with the reserve migration multiscenario report. Hence sorts that include PRMS qualifier, reserve class, category, and subcategory cannot be used with the reserve migration report. You should see a note such as "Selected Scenarios have incompatible PRMS for a MultiScenario Report using this sort." in the multiscenario report window. However, you can display summary at the PRMS reserve class, category, and subcategory level if you set these up as sub-totals in the selected sort order.

Example of a Reserve Migration Report

Sample Setup

To track reserve migration between multiple year end reserve report, 2022 to 2025, four scenarios and qualifiers has been setup for each year end period as shown in the screen shots below. In each period, the reserve class, category, and subcategory is saved in the PRMS qualifier for each case in your database. Since PRMS is a qualified data, you can store this value uniquely for each reporting period.
