Set +`Logging:LogRequests` to false to keep only warnings and errors. + +## Cost batches + +Saving an invoice also writes a posbdat price/cost batch for the items whose +cost moved. The invoice bills by the case, the product file costs by the unit, +so the comparison is `case cost / pack` against `Products.cost`; a gap of at +least `Batch:MinCostDelta` is a change, and an item with no cost on file counts +as one. Rows with no invoiced cost, and UPCs that are not in the product file, +are left out. + +The batch is written inside the same transaction as InvoiceHeader and +InvoiceDetail - if it cannot be written, nothing is saved - and +`InvoiceHeader.Price_Cost_Change` is set to 1 when the invoice produced one. +It is named `INV_` (`_1`, `_2`... if that name is taken) and +carries the new cost only; retail is left alone, and items whose gross margin +at the new cost falls under `Batch:MarginThreshold` are flagged on the archive +screen for manual repricing. Apply it the usual way (`sp_ApplyBatch`). + +The batch tables' column lists are read from INFORMATION_SCHEMA on first use and +whatever `Products` and `ProductBatches` genuinely have in common is copied +across, so a differently shaped install does not need a code change.
