Personnel Actions built before the upgrade to 2020.3 are not working correctly after upgrade

Description of Issue

We recently upgraded our TEST environment to 2020.3 from 11.3 and we are noticing our Personnel Actions are not posting correctly

Context
  • Munis version 2020.3; 2019.1; 11.3
  • Human Capital Management
  • HCM
  • Personnel Actions Entry
Cause

This issue stems from the rewrite of Employee Job/Salary and the addition of Effective Dated Pays 

Resolution

It is a requirement that prior to your upgrade from Munis version 11.3 or 2017.1 to version 2018.1 and higher that you post or delete all Personnel Actions
