Number Range Distribution to Devices 

Purpose

You can use this process to distribute number ranges from SAP Auto-ID Infrastructure to RFID device controllers during tag commissioning.

SAP Auto-ID Infrastructure provides the following interfaces that the RFID device controller can call to get number ranges:

●      Web service getNumberRange

The Web service requests a number range based on the IDs in the XML message.

●      RFC function module BAPI_AIISRV_GET_NUMBER_RANGE

The RFC function module requests a number range based on the actual objects. The function module supports the following number range objects:

○       GTIN

○       SSCC

○       GRAI

○       GIAI

○       CNSTR1EID

○       CNSTR2PART

For more information about this RFC function module, see the system documentation.

Process Flow

...

       1.      During tag commissioning, the RFID device controller commissions tags using the ID of the item and a serial number from a number range. When the number range is consumed, the device controller requests a new number range by calling either the Web service or the RFC function module. 

       2.      The interface calls the application programming interface (API) to get an appropriate number range.

       3.      The API updates the Current Number field of the number range table and sends an XML message that contains the requested number range to the RFID device controller. If the number range currently active has been completely consumed, the number range with the next sequence number is activated.
