Enterprise checks

- Do units of measure align with the claim method and ACE entry data?
- Are values, quantities, and time windows supported?
- Are claim rights and transfer records clear?

Substitution can unlock recovery where exact lot tracing is impractical. That matters for large manufacturers, chemical companies, electronics companies, retailers, and companies with commingled inventory. It also raises audit risk if classification and source data are weak.
