Working through a SAP Document AISAP Document AIserviceExtracts header fields and line items from invoices, payment advices, purchase orders and custom document types, as structured data over a REST API — the extraction is the service's, the schema can be yours.sap official, btp workshop, the author explains why its exercises teach extraction on a résumé before an invoice: a résumé has no stable layout to map fields against, so it forces the point that the tool extracts from a written description of a schema rather than from position-matched templates. Describing the schema is shown to carry real judgment — what a missing end date should become, what a vague field name like "number" costs the model, who in a company should decide these things — and the piece argues that preparing for a project is chiefly a business task of writing down knowledge that otherwise stays in people's heads.
