i reckon they will take both going concern and reporting period but they will only take reporting period if you say something along the lines that an asset presents future economic benefit which carries onto the next reporting period
No. I think RP is totally wrong. RP are just arbitrary periods of time that are used to calculate NP. It has absolutely nothing to do classifying assets (even as current/non current). A Period can be 2 weeks, it can be a year. Going concern is the umbrella principle that allows RP to exist. Assets are not recorded as expenses because of RP, but because of Going concern.
Only because of the assumption that the life of business is indefinite are we able to report Assets as future benefits. If there was an unknown end date to the firm in the future, all assets would be reported as expenses.
