A conversion must identify its rule, product and version; changing a factor must not silently recalculate closed records.
Index
Reporting production in pieces while consuming material in another unit creates unexplained differences when conversions exist only in spreadsheets.
The rule that changes the scope
A conversion must identify its rule, product and version; changing a factor must not silently recalculate closed records.
An ERP may cover fixed conversions; a complementary module manages factors varying with composition or production context.
Not every conversion needs automation in the first cycle. When a factor depends on a measurement not yet obtained, show the result as pending rather than use an unauthorized average. Scope should include source checking and the rounding convention adopted by the business. A report showing only the converted result prevents discrepancies from being traced; retain the entered value and its applied rule side by side for review.
Specify operational deliverables
- Connect the reported unit and converted unit to the same production entry.
- Show the applied rule and the person who validated the conversion.
- Keep earlier results when a new factor version becomes effective.
Test the exception before acceptance
In a hypothetical scenario, the factor changes during production; reviewed entries must retain their reference while new records use the current rule.
