Release 7.08.24 on 15.10.2026

This release aligns the XRechnung delivery date with the printed invoice, builds the header billing period from the contract lines, and fixes the price allowance sign on credit memos (PEPPOL-EN16931-R046).

Bugfix

• XRechnung CII invoices: BT-72 (actual delivery date) was taken from the header Shipment Date, while the printed SITE invoice shows the delivery date per line — so PDF and XML could differ. BT-72 is now the latest delivery date of the invoice lines, resolved with the same logic as the printout, with the header field as fallback. Installations without SITE are unchanged (CHN-463)
• The billing period in the header (BG-14) now spans the earliest start and the latest end date of the contract lines, for invoices and credit memos (INC-1791)
• Credit memos exported as type 384 wrote the price allowance BT-147 as a negative amount, so BT-146 = BT-148 − BT-147 failed (PEPPOL-EN16931-R046). BT-147 is now always positive, like BT-146 and BT-148
