Problem: At system option-Sales 4, tick on Show Discount, then go any sales entry, it will NOT show the footer discount when the GST module is enable.Possible to enhance: At Purchase module, can user enter Footer Discount at sales module? Because customer need to have total discount like 5%, 10% or value which is AUTO calculate. What we doing now is, call a service item enter the discount amount after we calculate, which customer complaint on it.
After the implementation of GST, global discount is not allow anymore, because one invoice may have standard-rated and zero-rated item in the same invoice, and a global discount cannot apply to both tax code. So, we have to create an service item code "Discount" and apply this discount in the item grid.
