Function: matchBasisIndex()

matchBasisIndex(checks): Map<string, string>

Defined in: src/db/queries/ar.ts:210

match_basis is NOT a column on check_payment_applications — it lives on the remittance LINE inside check_payments.remittance_lines (0049), merged there at confirm time. Index it per (check, invoice) so each application can find the basis that chose it; an application with no line (a check confirmed before the ref-first matcher existed) stays null, which is precisely the ledger's cause #5 signal.

Parameters​

checks​

readonly CheckDbRow[]

Returns​

Map<string, string>
