Hi
The historic volume for FY19 was imported as below.

and the following SYS13 Account SKU Filter system Module was created.

I then tested further with by changing the Time Scale to Week.

and got the following results (changed the pivoting to reflect the below format)

I am intrigue with the results above as we only loaded Historic Volume for FY19 under Time Range. What is the reason for various weeks under FY20 'tick-marked'?
