What you will do
Load a subcontractor's CSV export with German number formats, read the importer's warnings, remove a duplicate row and reconcile to the offer total; map an ambiguous workbook so the plan carries net rates; convert kilograms to tonnes and mesh to square metres with the rates; bring a 2024 price list in pounds to 2026 euros; and take in a revised offer by Position ID instead of appending it. Every figure is checked in the ERP.
