Hello Kumar,

The auto id test tool contains three format standards supported by SAP AII that can be used to support event and command communication between the device controllers/devices and SAP AII

The three formats are:

1) PML

2) ALE

3) SAP Web Services

The steps to configure and test web services are:

1) Releasing SAP Web Services:

a) Call transaction wsconfig

b) Enter following data and choose create

Service Defintion: /AIN/GET_NUMBER_RANGE_IN_VI

Variant: /AIN/GET_NUMNER_RANGE_IN

In the URL field of the Call Details Group box, make sure that the URl points to the correct ICF (Internet

Communication Framework) service (for eg; /sap/scm/ainws/get_number_range_in)

c) Save your entries.

Repeat the above steps for following

Service Definition: /AIN/NOTIFY_ERROR_IN_VI

Variant: /AIN/NOTIFY_ERROR_IN

Service Definition: /AIN/NOTIFY_TAGS_IN_VI

Variant: /AIN/NOTIFY_TAGS_IN

Service Definition: /AIN/STATUS_PING_IN_VI

Variant: /AIN/STATUS_PING_IN

Service Definition: /AIN/NOTIFY_EXTENSION_IN_V1

Variant: /AIN/NOTIFY_EXTENSION_IN

d) Save all your entries

2) Setting up RFC Connections:

Two RFC Connections needed

a) ALE_OUT/SAPWS_CMD_OUT

Connection Type: G

This RFC Connections will be used to connect to SAP ALE or SAP Web Service device controller, resepectively

3) Other RFCs needed

NOTIFY_TAGS_OUT

NOTIFY_EXTENSION_OUT

NOTIFY_ERROR_OUT

GET_NBR_OUT

STATUS_PING_OUT

Connection Type: H

Target Host: SAP AII

Service Number: SAP AII service number (Find out in sicf)

path prefix: Find in sicf

4) Define Logical Ports

Go to transaction LPCONFIG

For each RFC in step 3,

Proxy Class and choose Logical Port

Proxy Classes: /AIN/CO_IF_ALE_OUT, etc etc

5) Now use Auto ID test tool to use these services to send virtual read events to SAP AII.

Test the message in application logs slg1 transaction

Thnks

Thanks for the answer...

I am bit confused the difference between ALE and PML.

what is the main difference here....when should we use PML and ALE.Any perticular situation.

Hello Kumar,

my last answer for this post describes both situations as they are similar.

I have not come across any situation on which one should be used or not used out of ALE or PML.

These different communication interfaces have been defined by SAP just for the sake of device partners.

This gives the device and device middleware manucfacturers the flexibility to use any of the interfaces that they like and not depend on any one form. However internally they both use XML based messages itself.

One important point: As far as i know most of the mobile device manfucturers (which can connect devices directly to SAP AII) use PML for communication for its simplicity. And PML is the most common interface used in the case.

Thnks
