GTIN
Number Range
Request 
You can use this function to request number ranges from the ERP system for GTIN number range objects.
● You have set up the communication settings between the ERP system, SAP NetWeaver Exchange Infrastructure (XI), and SAP Auto-ID Infrastructure (SAP AII).
● You have created a material with a GTIN in ERP and in SAP AII.
● You have created a number range for the GTIN in SAP AII and set an alert threshold and an interval size.
You can use the following IDocs to request and receive GTIN number ranges from the ERP system.
● AIDRQ01 (Request IDoc)
Sends a number range request for a GTIN from SAP AII to the ERP system. When the alert threshold for a GTIN is reached, this IDoc is triggered and sent to the ERP system with the GTIN and the size of number range required.
● AIDNR01 (Number range response IDoc)
Sends a number range for a GTIN from the ERP system to SAP AII in response to a number range request. It contains the GTIN and a block of numbers.
When you create a number range for a GTIN and want to request number ranges for this GTIN from the ERP system, you define an alert threshold as a percentage of the number range and an interval size.
