53rd Week Inventory Handling

Question 1:

When read about timeshift function provided:

This mapping technique is primarily used when lagging measures between 52 and 53-week years.

When mapping multiple positions to a single position (such as mapping the last 2 weeks in a 53-week year to the last week in a 52-week year), the resulting value is the sum of the source values (that is, the sum of the last 2 weeks of the 53-week year).

When mapping a single position to multiple positions (such as mapping the last week in a 52-week year to the last 2 weeks in a 53-week year), the source value is replicated to the resulting values (that is, weeks 52 and 53 in the 53-week year are updated to week 52 in the 52-week year).
