This update improves the eBay sales integration by adding detailed logging to help diagnose issues more easily. It also reverts a previous change that inadvertently created new problems, allowing the team to investigate and fix both the original issue and the new problem together. This ensures a more stable and reliable eBay order processing experience.

These commits add logs and revert commit https://github.com/odoo/enterprise/commit/3f6143583a2b6f979c4bc703f3f333a1d818d0a2.
This commit, while working, broke the flow by showing another problem.
Reverting it to investigate deeper and fix both at the same time.

This update corrects the German DateV export format by adding a missing column for "Unternehmensgegenstand" (business purpose) in the proper sequence. This ensures the export file complies with DateV standards and can be properly processed by German accounting software.

This commit adds the column "Unternehmensgegenstand" between "Name (Adressatentyp Unternehmen)" and "Name (Adressatentyp natürl. Person)" in the DateV export.
