SAP S/4HANA Cloud Public Edition

1. Access Create Outgoing Invoice app
2. Fill out necessary information
3. Use an EU relevant Tax Code (EU Code <> space)
4. Warning Message F5 408 "Tax code & is EC-relevant, but document contains no VAT reg.no." is issued
   
   

Message F5408 is fixed as a Warning message and it is not possible to modify its type through configuration.

Utilize validation BADIs to create a custom validation ensuring that VAT Registration is entered for a line item with an EU Tax Code. Display a warning/info/error message to prompt the entry of the relevant VAT Reg. no if one is not yet provided. Validation in BAdI FIN_ACDOC_ITEM_VALIDATION can be configured to check whether an item has a tax code (ACCOUNTINGDOCITEMS-TAXCODE) that is EU-relevant (I_TAXCODE-EUTAXCLASSIFICATION) and whether the VAT Registration (ACCOUNTINGDOCITEMS-VATREGISTRATION) field is empty. 

For further details on how to use Custom Logic and Validation in Journal Entries, refer to the SAP Help documentation on Business Add-Ins for Validation for Journal Entries. Additionally, check the sample code provided for each BAdI.
