•  Hi Mansour,

The simplest implementation of that conversion would look something like this: Assuming your imported data is in a text-formatted line item called Week Code, you need a new date-formatted line item with the following formula:
`DATE(VALUE(LEFT(Week Code, 4)), 1, 1) + 7 * (VALUE(RIGHT(Week Code, 2)) - 1)`
This extracts a year number from the first four characters and a week number from the last two characters, then takes the first of January of the relevant year and adds the appropriate number of weeks.

That's in line with your description of the requirement. If you want to implement a standard week number algorithm (such as https://en.wikipedia.org/wiki/ISO_week_date) then you'll need a few intermediate steps.

•  Hi,
you can use a mix of following Anaplan functions :

Date(Year, month, day)
Start() to get the first day of the week.

To be more accrate in my answer, I need to knwo wheter you are using week as a timescale or as an imported data.

Kind regards.
Michel.
