Revenue example 7

Hi. Two questions please.

Firstly, are we expected to use the proforma method to calculate the contract asset for the SFP? Correct me if I’m wrong but the asset is accrued income plus contract prepayment.

Recognised revenue – amount invoiced = accrued income
Recognised costs – costs incurred to date = contract prepayment.

Add these values together and you get the same contract asset value as the proforma method. Would I lose marks by calculating this way?

second question, on this example, shouldn’t we be recognising the 8000 inventory on the SFP?
