GST Malaysia Tax Implementation

Hi Sir,

In the Malaysia government website, the GST tax type proposed is GST. However I notice SAP use only A for output tax and V for input tax. So should I create a new tax type GST for this purpose? Secondly, I notice the GST tax code listing have 2, 3 or 4 characters, however SAP standard provided 2 characters tax code only. Please advice. Thanks.
