How to read an xlsx general ledger (row-table ledger skill). The options are validated whenever they are sent (an invalid object answers 400), and are used when document jobs and DOCUMENT_LEDGER_ROWS_ENABLED are on; with either off, valid options answer 409 LEDGER_NOT_ENABLED rather than being ignored. A request carrying them never attaches to a live analyze job. Sending them confirms the column mapping, so a ledger that states no total is read without asking. Every field is optional: the header is recognised, the currency is the upload's and the region its site's country unless given. A request without them (a re-analysis) reuses the options of the upload's last confirmed read, as if sent again, so a currency or mapping the user confirmed is kept; options sent always replace them. columns maps fields (amount, date, account, accountName, creditor, creditorName, description, journalType, journalNumber, journalSource, reference, department, period, currency) to column letters and needs headerRow.
