Thank you for reaching out. I understand that you are looking for a way to fetch the current week number and the dates that fall under that week number in Pega. There are several ways to achieve this in Pega, and I would be happy to explain them to you.

One way to accomplish this is by using Pega's built-in functions for date and time manipulation. You can use the "CurrentDateTime()" function to get the current date and time, and then use the "WeekOfYear()" function to get the current week number. Once you have the current week number, you can use the "WeekStartDate()" and "WeekEndDate()" functions to get the start and end dates of the week.

Another approach is to use Pega's reporting capabilities to generate a report that shows the current week's dates. You can create a report definition that includes the date property and use the "Group by" feature to group the dates by week. You can then filter the report to show only the current week's dates. 

Finally, you can also achieve this by creating a custom function or activity that calculates the week number and dates based on the current date. This approach gives you more control over the calculations and allows you to customize the output as needed.

In conclusion, there are several ways to fetch the current week number and dates in Pega, depending on your requirements and preferences. You can use built-in functions, reporting capabilities, or create custom functions or activities. If you need further assistance or have questions, please do not hesitate to reach out.
