Hello AndreasMuno,

[KhaingZinTun]

Thanks for your information.

And I have another question, what BADI can I use from s4hana ABAP eclipse side for SupplierInvoice for showing error message,

Hi @KhaingZinTun,

thank you for your question. You may want to look up any and all S/4HANA Cloud Public Edition BAdIs on the Business Accelerator Hub at https://api.sap.com as shown before. For search term 'Supplier Invoice' I am getting a list of potential BAdIs: Business Add-Ins | SAP S/4HANA Cloud Public Edition | SAP Business Accelerator Hub.  As I don't know for which exact scenario you're looking to throw errors, you may want to explore those BAdIs on your own.
