Tax header file (F470461) for EDI invoices incorrectly populated when multiple rates

Dear all,

When invoicing an order with multiples tax rates for same tax authority and same tax area, the header file show zero for second rate and all tax amounts are summed under the first tax rate. On detail file, tax rate are used on different sales line with different tax Item (ok for me)

Exple detail file F470471 shows :

But Header file shows :

Whereas expected values on Header are :

Latest and closest SAR I've found is indeed installed : SAR 26493228 

Does any one have the same issue (With or Without workaround or Solution) ?

THank you

Best regards,
