Hi,

To compute the selection field based on the starting date, click on the 'MORE' button in the sidebar to open the form of the computation section.

Then paste the following code into the 'Compute' field:

for record in self:

    today = datetime.datetime.now().date()

    start_date = record.x_studio_starting_date

    if not start_date:

        record['x_studio_is_computed_field'] = False

    else:

        # Calculate years difference

        years = (today - start_date).days / 365.25

        if years < 1:

            record['x_studio_is_computed_field'] = 'A'

        elif years < 3:

            record['x_studio_is_computed_field'] = 'B'

        elif years < 5:

            record['x_studio_is_computed_field'] = 'C'

        else:

            record['x_studio_is_computed_field'] = 'D'

Here x_studio_is_computed_field is the selection field and x_studio_starting_date is the start date field. Replace x_studio_is_computed_field and x_studio_starting_date with your actual field names if they differ. Add the start date field to the Dependencies section under Advanced Properties to ensure the computed field updates automatically when the date changes.

Hope it helps
