In both the Subsidiary views training video and in the Planual it mentions that Subsidiary views should be used where a ratio needs to be in the same module but doesn't full require full dimensionality
Can anyone provide an example of this I'm I can't picture it
Basically, unlike filters, you can't reference a line item that is not in the same module for either the numerator or denominator of the Ratio summary method so you have no option but to include it as a subsidiary view (if it doesn't require the same dimensions of the module)
