Version 22 R1
I have added custom fields to accept shipment location and ship via in the sales order and split shipment is created based on location and ship via for the selected warehouse.
I have override the ARInvoiceEntryExternalTax && SOOrderEntryExternalTax GetToAddress with line parameter to get the Location address selected in the line. These changes are working fine in 20 R2 and calculate the tax based on the location selected in line, but in 22 R1 it calculates tax and failed to calculate tax in the Sales invoice and throws an error: TX Error: Failed to get taxes from the external tax provider.
