ACA Prime - if employee waive his enrollment, and its waive enrollment is terminated then termination date should be blank on file

As per request from the client,
If employee is waive its enrollment and its waive enrollment is terminated then on Prime files Termination Date should populate as Blank.
We have done this in manual DB Script of Prime files.

Approach : We can do this using Rule engine,
1. We have to map Termination Date field with - ACA export waive termination Date
2. In rule engine we will have to check if the employee is waive it benefit and if it is terminated then make it blank using Rule Engine while writing on file.
