Central Number Range Administration 

Purpose

You can use this process to control the creation and distribution of number ranges in a system landscape with SAP object event repository (the repository) and multiple local instances of SAP Auto-ID Infrastructure (SAP AII). This helps you to ensure the uniqueness of serial numbers across your enterprise and makes tracking of individual IDs easier and more reliable.

Prerequisites

●      You have defined the instance types of the systems in your system landscape.

○       In your local SAP AII in Customizing, you have defined SAP AII as the local instance. For more information, see the Implementation Guide (IMG) for Auto-ID Infrastructure under Basic Settings ® Define Client-Specific Control Parameters. You must do this for each local SAP AII for which you want to request number ranges from the repository.

○       In the repository in Customizing, you have defined the respository as the central instance. For more information, see the Implementation Guide (IMG) for Auto-ID Infrastructure under Settings for SAP Object Event Repository ® Define Client-Specific Control Parameters.

●      You have set up communication settings between the repository, SAP NetWeaver Exchange Infrastructure (XI), and local instances of SAP AII. For more information, see SAP Service Marketplace at service.sap.com/rfid® Detailed Information.

Process Flow

...

       1.      You upload all existing number ranges from your local SAP AIIs to the repository.

       2.      You create overall number ranges for number range objects in the repository.

       3.      In a local SAP AII, you request initial number ranges from the repository, if number ranges for number range objects do not already exist.

       4.      RFID devices request and consume number ranges from local SAP AIIs.

For more information about the distribution of number ranges from SAP AII to RFID devices, see Number Range Distribution to Devices.

       5.      The local SAP AII sends a number range request to the repository via XI when the alert threshold of a number range in a local SAP AII is exceeded. The number range request contains information about the number range object and the size of interval required.

       6.      The repository returns a new number range interval to the local SAP AII via XI if an overall number range for the requested number range object exists in the repository.

If the repository cannot fulfill the request, for example if the overall number range is completely consumed, the request is rejected. You can then manually correct this in the repository, for example by increasing the Number To of the overall interval, and resend the request from the local SAP AII.

       7.      You can also block and allocate number ranges in the repository for external systems.
