第一个空号 (tcmcs0150m000)

A group of first free number series that you can assign to a specific use.

For example, you can assign a number group to:

• Business partner codes
• Purchase contracts
• Sales orders
• Production orders
• Service orders
• Warehousing orders
• Freight orders

Within a number group you can define multiple series. Each series is identified by the series code. The series numbers that LN generates consist of the series code followed by the first free number in the series. Series codes of the same number group have the same length.

The series code.

允许值

The series code must have the same number of characters as defined for this number group's series length in the 编号组 (tcmcs0151m000) session.

If the number group is dedicated to a specific use, the series code must be unique in the number groups dedicated to the same type of use.

To improve the performance of sessions in which new order numbers are assigned, you can define a cache size for a series. The cache size is the number of new series numbers that LN generates at once. If there are series numbers in cache, users do not have to wait while LN generates and checks the next series numbers.

允许值

• Cache size = 0

  No caching is applied. If you request a new number, the number is only committed after the transaction to which the number applies is completed.

  Disadvantage: The number series is locked during the transaction. Other users cannot request a new number from the same series until the transaction is completed.

  Advantage: No numbering gaps.

  Use a cache size of 0 if number gaps are not allowed. Preferably, request a new number close to the end of a transation to reduce locking time. In high volume implementations, a cache size of 0 may cause performance and locking issues.

• Cache size = 1

  If you request a new number, the number is committed immediately, even if the transaction to which the number applies is not yet completed.

  Disadvantage: Numbering gaps may occur if a transaction is not finished.

  Advantage: The number series is locked for only a short time, which improves performance.

  A cache size of 1 is the default value for number series. In this way, performance and locking issues in high volume implementations are avoided as much as possible.

• Cache size > 1

  The value of the cache size indicates how many new numbers are requested at once. The numbers are committed immediately, even if transactions are not yet completed.

  Disadvantage: Large numbering gaps may occur if more than one transaction is unfinished.

  Advantage: The number series is locked for only a short time. Furthermore, for all numbers that are requested, the number series needs to be updated only once, which improves performance.

  A cache size larger than 1 is only recommended if a cache size of 1 does not solve locking issues sufficiently.

To improve the performance of sessions in which new order numbers are assigned, you can define a cache size for a series. The cache size is the number of new series numbers that LN generates and puts in the user's cache. The users do not have to wait while LN generates and checks the next series numbers.

If you use the first free numbers cache, the order numbers can be nonsequential; the numbers that are still in the user's cache are lost when the user logs off.

If you do not want to use the first free numbers cache, you must set the cache size to zero.

如果选中此复选框， you cannot use the series. If you block a series, you must select another series for the type of orders or other elements to which the series is assigned.
