Scrap can generate a recycler credit while the production system records a quantity loss. Those two records rarely share an identifier, so a monthly net entry can hide both missing proceeds and unexplained usage.
A workable manufacturing scrap credits schedule names the entity, period, currency, source systems, cutoff, preparer, and reviewer. It also records the report filters and extraction time. Those details let the next reviewer reproduce the work instead of trusting an unexplained total.
