What does the packaging mass balance checker produce?
Calculate opening stock plus input minus output, scrap, and closing stock. Compare exact decimal imbalance with your tolerances and recorded variance.
The working area above runs the supported validator in the browser. It keeps the result inspectable and preserves every unresolved item for responsible review.
What do you need before you start?
- A named owner has defined the task and the organization’s intended use.
- The customer has authority to use every supplied record, source or connection.
- Prepare the result in this browser and resolve visible input errors before exporting.
What information do you enter?
Prepare only the bounded inputs listed below for this validator.
- Frozen review date (required). Use a real YYYY-MM-DD date from 1900 through 2200. The tool does not use the browser clock.
- Approved policy and scope reference (required). Identify your rule, version, reporting scope, and responsible reviewer. No legal requirement is inferred.
- Common mass unit (required). Use one exact unit, such as kg, for every source mass. No unit conversion occurs.
- Relative variance tolerance in percent (required). Compare absolute imbalance against available mass times this percentage. Equality passes.
- Absolute variance tolerance in the common unit (required). A row passes when absolute imbalance does not exceed the larger absolute or relative tolerance. Up to six decimals.
- Treat missing stock and scrap values as zero (required). Select Yes only when your approved reporting scope explicitly excludes opening stock, closing stock, and scrap. Otherwise those three columns and values are required.
