Hi,

We are trying to integrate external supplier invoices via the eInvoice module.
As this post Community : 
https://community.ifs.com/finance-financials-42/e-invoice-tax-code-is-not-fetched-from-extern-supp-inv-tax-code-16229?tid=16229&fid=42

We are unable to retrieve the tax code for the supplier configured in the "External Supplier Invoice Tax Codes" screen.
A solution is proposed in this post, but it doesn't work for us...
We are in 23R2 for your information.

How can we solve this problem?

Thanks in advance.
