Oracle R12 Malaysian GST 21 day rule
There is a requirement that if the invoice is not issued within 21 days of the service being supplied then a different tax date is required.
This could be handled with a patch (For automated tax date for AP and AR transactions – patch 12726737 – Used for ECE reports) from Oracle that will apply a tax date to every transaction but unfortunately this patch is country specific so won’t work for Malaysia.
We can however still use European setups to capture the tax date as a way of doing the tax reporting. What this means is that whilst an invoice, either in AP or in AR can have an invoice (or transaction) date, but a customization would be needed to update the tax date because Oracle does not do this for us.
