The current resource work week is the week number calculated from the Schedule Options' Manufacturing work week 1 date.  For example, if the Manufacturing work week 1 date is Jan 1, 2019 and the schedule start date is Jan 14, 2019, the current work week would be 3 and the current resource work week would be:

• 1 if there is one variable work week
• 1 if there are two variable work weeks
• 3 if there are three variable work weeks
• 3 if there are four variable work weeks

As another example, if the Manufacturing work week 1 date is Jan 1, 2019 and the schedule start date is Jan 21, 2019 (one week later than the above example), the current work week would be 4 and the current resource work week would be:

• 1 if there is one variable work week
• 2 if there are two variable work weeks
• 1 if there are three variable work weeks
• 4 if there are four variable work weeks

The current resource work week is used by the scheduler to what resource profile to use.  If you have 2 variable work weeks and a resource has 2 defined resource profiles, the scheduler will use the resource week 1 profile if the current resource work week is 1, and use the resource week 2 profile if the current resource work week is 2. 

If a resource has only one work week defined than the scheduler will always use the resource week 1 profile regardless of the current resource work week.

During a schedule run, the user can change the current resource work week for that schedule run.
