TDS — Total Monetary Value Summary
X12 TDS segment on EDI 810 invoices: total invoice amount and how it must reconcile with IT1 line totals.
TDS segment facts
- TDS01 must reconcile with rolled-up IT1 line amounts — cent-level drift causes retailer invoice rejects.
- Implied decimal rules differ by partner; SignalEDI partner profiles can enforce the correct TDS scale.
- Accounting handoff previews show TDS totals before invoices post to QuickBooks drafts.
What the TDS segment does
TDS states the invoice total. Partners compare TDS against summed IT1 amounts; mismatches are hard rejects or short-pay triggers.
Loop: Once per 810
