Peoplesoft cross-plan matching between 457(b) employee contributions and 401(a) employer match

We are introducing a new 401(a) employer-only plan for 2027. Currently, our existing 457 plan handles both employee and employer contributions. Effective next year, the 457 plan will be reconfigured for employee-only contributions, while all employer contributions transition to the 401(a).

For most of our business groups, configuring the employer contribution on the Savings Plan Table using a standard percentage of base pay works cleanly. However, one of our union/bargaining groups requires a 100% employer match on employee 457 contributions (pre-tax and Roth) up to 3.5% of eligible earnings into the 401(a).

While the Service Step Table matching logic handled this easily within the single 457 plan type, delivered setup does not support cross-plan matching (calculating a match in a 401(a) plan based on deductions taken in a 457 plan).
