Maintain First Free Numbers data (T)

  1. Expand Master Data applications > Tables.
  2. Select Logistic Tables > First Free Numbers.
  3. Click the New View icon.
  4. In the Number Group field, search and select a Number Group code. This code was previously created to group your number series. Click OK.
  5. To create the number series, click New.
  6. Specify this information:
    Series

    Specify a group of order numbers or document numbers that start with the same series code. Series should be equal to the series length defined in your Number Group and can contain alphanumeric characters.

    First Free Number

    Specify the first free number, which is the first available number within a series. You can specify a numeric value between 1 to 9. This field is mandatory.

    Cache Size

    Specify a cache size, which is the number of new series numbers that Tax Engine generates at once. If there are series numbers in cache, users do not have to wait while Tax Engine generates and checks the next series numbers. These values are allowed:

    • 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 for a new number from the same series until the transaction is completed.

      Advantage: No numbering gaps.

    • Cache size = 1

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

      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.

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

      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.

    Blocked for Input

    If this check box is selected, 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. You can clear the check box to resume using a series.
