Initial Number Range Request 

Use

In a local instance of SAP Auto-ID Infrastructure (SAP AII), you can request an initial number range for a number range object from SAP object event repository (the repository). This triggers central number range administration.

Prerequisites

You have created an overall number range for the number range object in the repository.

Features

This function is available if a number range object, such as a specific GTIN, exists in the master data of the local SAP AII but has no number range, and when you have uploaded existing number ranges from the local SAP AII to the repository.

If you do not request an initial number range from the repository for a specific number range object type but instead create a number range locally, number range administration for this number range object type behaves as standalone. You can then create and maintain number ranges for this number range object type in the local SAP AII without interaction with the repository.

Activities

When you request a number range in a local SAP AII, the system sends the request via SAP NetWeaver Exchange Infrastructure (XI) using the interface NumberRangeRequest. The repository returns a response via XI using the interface NumberRangeConfirmation. This response can be either an initial number range for the number range object or a rejection if, for example, the number range for the number range object is already consumed. In the repository, the current number of the number range is increased by the requested interval and in the local SAP AII the number range object has the status Request Sent. The request is also logged and you can see this by selecting the number range in the repository. In the local SAP AII, a number range is created on the local instance with the status Request Completely Confirmed or Request Partially Confirmed if the repository was only able to deliver part of the requested number range.  

If the repository rejects the request, the number range object has the status Request Rejected in the local SAP AII. You can manually correct this by increasing the upper threshold of the overall number range in the repository, that is the number in the Serial Number To column and resending the request from the local SAP AII.

You send initial number range requests and resend rejected requests for a new number range object together with the alert threshold and the interval in the local SAP AII on the SAP Easy Access menu under Auto-ID Infrastructure ® Master Data ® Number Ranges ® Number Range Administration.

Example

You have introduced a new product with the GTIN 00037000442205. In the repository, you create an overall number range for this GTIN. In the local SAP AII, you send an initial request for the GTIN 00037000442205 to the repository with an alert threshold of 80 percent and an interval of 50. The repository returns a number range for the GTIN and increases the current number of the overall number range in the repository by 50. You perform tag commissioning and distribute this number range to the RFID devices. When the current number of the number range in the local SAP AII is 41, that is when the 80 percent alert threshold is exceeded, the local SAP AII automatically sends a number range request for a new number range to the repository.
