Bucket
It refers to an individual period indicated by MRP list. Speaking of "the size of Bucket", it shows the size of one period, and how detailed MRP's plan is depends on how long or what days the bucket is set.
The size of bucket is usually 3 to 7 days, and the period to be planned is mostly 3 to 6 months. If the size of bucket is set to 3 days, the planned period is set to 3 months, and monthly operation days are set to 22 days, 22 of buckets are needed. The bucket quantity is related to the MRP's processing time, and thus it should be set within the necessary period of time. The size of bucket depends on the details of purchasing or manufacturing such as the cycle of manufacturing instructions and the frequency of collecting performance.
