Count workdays with between to dates unless training date is after start date

My problem I want to solve is when the training date is later than the start date in the slicer,  I want it updated to show the start date as the training date and recalculate the number of required activities.

I have a DimDate table where I have a column stating true or false if the date is a workday, (it excludes weekends and Holiday)

Each person record has a column with the number of activities per day required based on job title. Which is 1 per workday for supervisors and 3 per week for managers.

I have at training file with the date they were trained in the process.

This is the current calculating the total activities due for 10/1/22-10/31/22  our company has no holidays in this month.

The first supervisor was trained on 10/17/22

The MGR II was trained on 10/20/22

The other two were trained last year.

The table should show:

The first supervisor as required to 10 in the Goal column

The MGR II with a goal of 4 days

The other two supervisors are correct.

This is the formula for counting only work days.

NBR Days = --this excludes holidays and weekend--

COUNTROWS(

     FILTER(DimDate,DimDate[SA_Workday] = TRUE()))

This is the formula for assigning the goal.

Min SC Expectation = // CrossFilter ignores the relationship between dim date table and safety events table to get all users and goals listed

calculate(SUMx('All Employees','All Employees'[Min Contact/Week]) * [NBR Days], CROSSFILTER(DimDate[Cal_Date_DT],'Safety Event Entry_Safety Event Entry - Daily Report'[Date Performed], None))
