| Bucket Definition (tiasl1100m000) |  |
| Use this session to define time buckets for use in assembly control. Allocation and backflushing are done per line station per bucket when you use Line Station Based Transaction Processing, which means that all the line station orders in one bucket are combined. This reduces the number of transaction, compared with Order Based transaction processing. The performance is further enhanced if you use larger buckets, because this reduces the number of transactions. After you define the buckets, you must run Generate Buckets, which is available from the Specific menu, to generate the buckets for the full allocation time fence in Assembly Control (ASC). The buckets for the period length must be the same as for the Allocation Time Fence, which is defined in the Assembly Control Parameters (tiasc0100m000) session, because allocation is done within the allocation time fence. It is best to define a whole number of buckets per day. If not, your buckets will be of different lengths. For example, if you enter 10 hours into this field, ERP LN will generate two buckets each of ten hours and one bucket of four hours (for one day of 24 hours). If you make many changes to assembly orders you should make your buckets smaller than if you make few changes. Example In the current session you enter the following:
Period | No. days | Bucket length | Unit
1 | 1 | 1 | hour
2 | 1 | 4 | hour
3 | -1 | 8 | hour
In the Allocation Time Fence field of the Assembly Control Parameters (tiasc0100m000) session you can enter, for example, 5 days. The number of working hours to the day for an assembly line is defined using the Calendar Code field of the Assembly Lines (tiasl1530m000) session (this example assumes 8). When you select the Generate Buckets option, the following buckets are generated:
Bucket | Day number | Start | End
1 | 1 | 8:00 | 9:00
2 | 1 | 9:00 | 10:00
3 | 1 | 10:00 | 11:00
4 | 1 | 11:00 | 12:00
5 | 1 | 13:00 | 14:00
6 | 1 | 15:00 | 16:00
7 | 2 | 8:00 | 12:00
8 | 2 | 12:00 | 16:00
9 | 3 | 8:00 | 16:00
10 | 4 | 8:00 | 16:00
11 | 5 | 8:00 | 16:00
The final two lines were created because the allocation time fence was filled. Note You can view the buckets you have defined with the Buckets (tiasl1501m000) session. You can print out the data you have entered in this session, by selecting Print Bucket Definition from the File menu.

Fields | Description
Period | The number of the bucket definition.
Number of Days | The maximum number of days the bucket definition is valid for. You must enter an integer.
Bucket Length | Enter the length of the bucket. You define the unit of the length (for example, hours) in the next field. It is best to define a whole number of buckets per day. If not, your buckets will be of different lengths. For example, if you enter 10 hours into this field, ERP LN will generate two buckets each of ten hours and one bucket of four hours (for one day of 24 hours).
Bucket Length | The unit of measurement of the Bucket Length, for example: hours.
Commands | Description
Generate Buckets | Click to generate buckets using the settings you have defined in this session.
