I was verifying my SYS01 module line item with what was given in training exercise I found discrepancies over theirs. IN my module line items like 1st Week of timescale? & Weeks only? line item are not present. For the 1st week timescale? line item I directly use OFFSET formula in Not 1st-week timescale? line item but I don't come across any instruction where we need to add Weeks only? line item. Am I missing something?
