How to modify deduction to consider wages on Regular and Separate Pay?

Summary:

For associates who are highly compensated and have a fixed election for RSP and who receive pay via regular normal and pay sep/process sep, the 7% cap is not taking into account all wages, but rather only those paid on the Reg Normal cycle. This leads to an under calculation and deduction for RSP.

Content (required):

The deduction should take into consideration all the wages available between regular and separate pay and take what it can from regular pay. If there is a remaining amount to be satisfied, it should be taken from separate pay if there are earnings available. Any other uncollected amounts should be arreared.
