Reconcile your line list with records checked against the P&ID.
Compare your line list with records you have checked against the P&ID. Identify missing lines and disagreements before handoff.
One row per line identity. Match case and leading zeros exactly. Size labels are compared as text; units and flow direction are not inferred.
Prepare reviewed drawing records first. A missing line can indicate a scope difference; a repeated line number may need separate segment identities. Resolve each finding against the controlled drawing.
