Hello,
when adding tax to a invoiceproduct CRM calculates the extended amount automatically. If the tax calculations is performed with a plugin or manually doesn't matter at this point.
On the invoice CRM also calculates the sum of all lineitems of the invoice for amount, tax and extended amount. this is also working correctly.
When you now apply a discount on the invoice CRM dos not reduce the tax in relation to the reduced totalamount.
Is there any solution for this?
