Our client has Concur tool interfaced with SAP. They use Taxware system for tax calculations. Recently Taxware upgrade has been done. After the upgrade while posting FI invoice (FB60/ FB01 with posting keys 31, 40), we noticed that the line item for Tax is not created and above error message is generated in SAP. Before the Taxware upgrade the Tax line was properly calculated. I checked the configuration and I dont see any issue there. We are ECC EHP7. I am suspecting that a SAP note is to be applied.
