Cumulative lead time is a key concept in Oracle Manufacturing Cloud, where it calculates the total time required to manufacture an item. The following points clarify the calculations:
Statement D is incorrect because cumulative lead time does not update the lead time percent at the operation level in the work definition. Instead, cumulative lead time focuses on rolling up the lead times of both make and buy items to provide an overall lead time for the entire production process.
Correct Statements:
Statement A: The system calculates cumulative manufacturing lead time by summing up the lead times of all make items in the production process.
Statement B: At the end of the cumulative lead time calculation process, it updates the lead time attributes of the item, specifically cumulative manufacturing and cumulative total lead times.
Statement C: Cumulative total lead time includes both make and buy item lead times, representing the complete production cycle from procurement to manufacturing.
