I want to change an item Tax Group id of an particular item corresponding to all sales line in table.
Real Problem happened:
Global setup for that item, item tax group is assigned wrongly, so all sales line created for that item has the same itemtaxgroup id.
Am planning to run a job to update taxItemGroup id for all sales line to that item. Will it affect any tax calculation when invoice is created?
Please share your ideas.
Thanks & regards.
