Subtotal discount
Type of operation: 0=value discount, 1=value surcharge
It applies to the turnover at the tax level - if no sale was made at that tax level, the command will declare an error and will not be processed.
If a percentage discount is to be used, it needs to be calculated in the sales application and the value needs to be sent to eKasa.
In the case of a return, the opposite type of operation must be used (discount used in sale is returned as a surcharge parameter-wise).
