PositionOf is a simplified version of the RankOf function. Rather than applying rules on the input Table to determine ranking position, it simply returns the row position of the searched label within the provided Table as-is.
If the searched label is not found in the Table, the function returns a missing value. We have shown earlier how we can make use of this behavior to determine if a given label appears in a different Table, in order to filter out some rows. As another use case, see how it can be used to check within a dynamic row if a given make also has data for a different period.
