Before revision:  Hence we propose a Revised SA-CCR (RSA-CCR) based on cashflow decomposition and this 3-factor Gaussian Market Model . RSA-CCR is free of SA-CCR's issues, simple to use in practice, and can be extended easily given that it is model-based. We recommend updating SA-CCR to RSA-CCR in order to resolve SA-CCR's issues of lack of self-consistency for linear trades, lack of appropriate risk sensitivity (zero positions can have material add-ons; moneyness is ignored), dependence on economically-equivalent confirmations, and ambiguity of application for cases not explicitly described.
