Hello
As per the Law in UK, input tax must be repaid to the tax authorities if the invoice has not been paid after six months. If an invoice is unpaid 6 months after the due date (so if payment were due within 30 days, that’s 7 months after the invoice date) then you should adjust the next VAT return to repay to HMRC the VAT that was previously reclaimed. If the invoice is paid later, then the VAT can be reclaimed again.
In the on premise world there is a standard program RFUMSVHU to generate the required report.
Can you please confirm if there is any such report/functionality available in the S/4 HANA Cloud?
