Change Tax Code after Partial Delivery for Sales Order
The government in my country has changed the GST (Goods & Services Tax) in my country from 5% to 7%. In my system I have created a new 7% Tax Code and assigned it to Condition Type MWST with a new validity date.
For newly created Sales Order, my pricing procedure gets the correct 7% Tax Code for MWST based on Pricing Date that is later than the validity date I've set.
However, my problem lies with partially delivered/invoiced Sales Order when updating of prices are not allowed. One possibility I can think of is to allow Condition MWST to be maintained manually and change it during Billing process. But I'm looking for a solution without change the Configuration if possible.
Can anyone propose a good solution to my problem?
