Validates synthetic intercompany line items with five rules and builds a seller-by-buyer matrix in euros.
What it does
Generates synthetic SAP-style intercompany line items, checks every document against five rules (missing counterleg, amount or currency mismatch, unknown entity, duplicate leg), writes failures to exceptions.csv and turns the rest into a seller-by-buyer matrix in euros, ic_matrix.xlsx. Runs with pip and python run.py, with a pytest suite. Synthetic data only, with five planted defects; MIT.
Where it fits on the map
Not on the map: a demo.
The map places maintained projects for a company tax department or a tax authority, without a demo or paid-service flag. Everything else stays on the list with its label.
