2829369 - Base Salary Value Changes to Negative Percentage When Pay Target is Added

When adding a pay target to an employee, the pay component base salary amount and/or frequency get erased and turn to a negative percentage value

Employee Central - Pay Component

Employee Central - Business Rule

Compensation Information - Pay Target

1. Go to any employee profile
2. Go to actions  - compensation (or simply edit the compensation portlet)
3. Scroll down to Pay target
4. Add any Pay Target 
5. Notice that the amount and frequency get erased and the amount displays negative percentage value

This behavior is dictated by a business rule configured in the system:
a propagation rule like (migratedRule__xxxx)
This rule is set to trigger onChange from "Pay Component".
To verify and confirm this behavior, disable all the migrated rules on this field and add them back one by one to find the one causing the behavior.

As such this would be an expected behavior based on current system configuration

If you do not want this behavior disable the indicated rule

NOTE:

These migrated rules are among those that were converted from xml to business in 1902 release.

This behaviour would be particularly prevalent with instances built on the backbone of Model Companies.
