FD 008
Assigning a new tax key for VAT not possible
Inbound invoice processing fails with FD 008 while SAP tries to derive or assign a tax key from inbound tax data.
Quick answer
- Most likely cause
- The inbound tax indicator or VAT data has no valid mapping to an SAP tax code.
- Check first
- WE02/WE05 — inspect the inbound tax-related segments and the full status message.
- First resolution step
- Confirm the intended tax treatment with Finance.
Likely root causes
- The inbound tax indicator or VAT data has no valid mapping to an SAP tax code.
- The tax code is not valid for the receiving company code/country context.
- The incoming EDI tax information is incomplete or inconsistent.
What to inspect
- WE02/WE05 — inspect the inbound tax-related segments and the full status message.
- Tax code configuration for the receiving company code and country.
- EDI mapping that converts external VAT/tax indicators into SAP values.
Resolution path
- Confirm the intended tax treatment with Finance.
- Correct the inbound tax mapping or master/configuration value that is missing.
- Retest with a representative invoice before mass reprocessing.
- Reprocess failed IDocs after the tax mapping is validated.
