Order-to-Cash (O2C)

Create SO → Check Credit → Release SO → Create Delivery →
Pick → Pack → Ship → Create Invoice → Post Invoice → Receive Payment

Usage

use datasynth_ocpm::{OcpmGenerator, P2pDocuments};

let mut generator = OcpmGenerator::new(seed);
let documents = P2pDocuments::new("PO-001", "V-001", "1000", amount, "USD");

let result = generator.generate_p2p_case(&documents, start_time, &users);

Export

use datasynth_ocpm::export::{Ocel2Exporter, ExportFormat};

let exporter = Ocel2Exporter::new(ExportFormat::Json);
exporter.export(&event_log, "output/ocel2.json")?;
