-- =============================================
-- Description:	Set-based counterpart of the scalar [fds__fn_InvoicePaymentAmount]:
--              returns the summed (non-storno) banking payments for EVERY invoice in one pass
--              over [fds__fn_bankingtransactions]. Join it instead of calling the scalar
--              function per row — the scalar one declares a table variable, so SQL Server
--              cannot inline it and re-runs the whole banking TVF for each invoice
--              (~0.5 s × N rows; the overdue-sum widget timed out at 90 s with 187 rows).
--              Same semantics as the scalar version with an empty id list: all invoices,
--              no date filter, storno credits NOT included (see *_full for those).
