We are testing the ERS Invoice Scenario in SNC. We are able to post the invoice succesfully and view them in the SNC web UI. But the Tax Amount and Gross Amount fields at the Item level are not getting computed (Value = 0.00).
1. I have maintained the IMG setting "Maintain Tax Codes for Invoices" (SPRO > SNC > Invoice > Maintain Tax codes for Invoices)
2. To verify that the system is accessing this config table during inbound processing, I deleted all the entries. Then the Invoice used to fail during validation with the error message "Tax code not available".
Inputs on how to debug and identify the soucre of error will be useful.
