The Management of Tag IDs and Tag Observations ES bundle uses the business object Automatic Identification Label (SCM). The enterprise services in this ES bundle enable the warehouse worker to attach labels such as RFID tags or barcodes to an item. The business object Automatic Identification Label (SCM) models an automatically identifiable label, such as an Radio Frequency Identification Devices (RFID) tag that can be attached to an item. These labels can then be observed by an Auto_ID capturing device, and, in turn, these observations allow you to automatically monitor events relating to the item, such as packing or shipping in the supply chain.

The Automatic Identification Label (SCM) business object models an observation of an ID by an RFID device. This corresponds to an observation that has occurred involving an object in your supply chain that is identified by an automatically identifiable label, such as an RFID tag. Such observations can be used to monitor movements of items to automate and optimize logistic processes. The Management of Tag IDs and Tag Observations ES bundle provides enterprise services that you can use to record and search for observations in SAP Auto-ID Infrastructure (SAP AII).

You can use the enterprise services in this ES bundle to support the following operations:

  • Commissioning and decommissioning tags
  • Changing and searching for tags (tag management)
  • Printing tags
  • Encoding and decoding tags
  • Creating an RFID device observation
  • Searching for a device observation

Audience

The Management of Tag IDs and Tag Observations ES bundle can be deployed in virtually all business scenarios involving an RFID-enabled product for providing visibility and tracking. This ES bundle is valuable to all businesses interested in simplifying or extending usage of RFID, whether through custom user interfaces or by connecting the application with other software. Partners and customers could take advantage of the enterprise services provided in this bundle so that they can deploy composite applications more quickly and with less development effort.

How to Use This ES Bundle

This ES bundle includes enterprise services related to two business objects:

The enterprise services in this ES bundle enable the warehouse worker to attach labels such as RFID tags or barcodes to an item. These labels can then be observed in subsequent processes by devices to automatically monitor events related to the item, such as packing or loading.

This section will explore a series of use cases for the Management of Tag IDs and Tag Observations ES bundle. Each use case will show how different outcomes can be achieved by using the enterprise services in different combinations. While these examples illustrate some of the ways that this ES bundle could be used, the intention is to show the flexibility and reusability of these business objects and enterprise service operations so that you will have a clearer understanding of how to best deploy them in your own environment. The use cases are written this way to illustrate the logical flow of the services; in actuality, end users access the enterprise services through an interface and the business objects and enterprise services are working behind the scenes. Please note that this wiki is also a space for you to share knowledge and collaborate with others who are implementing the ES bundle, so please come back and share your experiences with this bundle after implementing it.

Use Case 1: Auto Id enabled Outbound process using Enterprise services

A pharmaceutical company receives a purchase order from its customer. The salesperson creates a sales order and a delivery document in SAP ERP. Prior to packing the order, the warehouse staff wants to commission RFID tags for the products to be shipped in the sales order. The warehouse staff commissions the tags by invoking the Create Label enterprise service. The pure ID is converted to hexadecimal format using the enterprise service for encoding Encode Label then they can print the commissioned tags using the Print Automatic Identification Label enterprise service. Printed tags are attached to the product and the product is made ready for shipment. During the packing process, warehouse staff scans the pallet tag, and SAP Auto-ID Infrastructure invokes the Create Observation enterprise service to register the observation.

During the scanning process, the tag ID is decoded using the Decode Label service prior to updating SAP Auto-ID Infrastructure. In order to track the movement of items along the supply chain, authorized users can invoke the enterprise service Find Observation by Elements.

Use Case 2: Management of Tag Ids and Observation using Enterprise Services

After tag commissioning, a member of the warehouse staff needs to change the details of the tag. Immediately, he can use the enterprise service Find Label by Elements to search for the commissioned tags, followed by Read Label enterprise service to read the details of the tag to be changed. The worker makes the changes and then invokes enterprise service Change Label to change the tag details. Should the worker need to decommission the tag, he could invoke the Cancel Label enterprise service instead.

Future Directions

Future enterprise service development in the Management of Tag Ids and Tag Observations ES bundle could provide more options for configuration of creating and managing tag IDs and observations in SAP Auto-ID Infrastructure.

System Requirements

Depending on the type of user interface, the user might need SAP NetWeaver Visual Composer to develop a guided procedure or create a composite application using SAP NetWeaver 2004.
