2.0 SAP WEB CONSOLE vs ITS MOBILE

SAPwebconsole and ITS mobile has lot of technology differences and each has pros and cons in terms of
technology, architecture, limitations and usage in warehouse. Following matrix helps in understanding solution to use while implementing RF solution that suites to your business requirements on ITS vs SAP webconsole. Following matrix explains key differences between SAPWebconsole and ITS Mobile.

Category	SAPWebconsole	ITS Mobile
Mature solution	Industrial RF devices at warehouse or retain stores are very matured and stable solution successfully using more than 25 years solution	RF & Mobile devices using since 2004 are relatively matured but web based solution is still evolving.
Usage in industry	More useful in industry where character based or text based applications are required and usage of web browser are limited.	It is more useful to mobile browser application in warehouse
Programming language	ABAP	ABAP & HTML
User support	It support around 225 user per window	It supports large number of users.
Device software	It requires VT220 terminal emulation for RF character(text) device and browser that supports the mobile client	Any device that support internet browser.
Sign on	It requires sign on in SAP Console, Telnet and ECC	Single sign on ITS as SAP Netweaver is part of SAP product. Also support connection encryption and external authentication.
Performance	RF performance is better than browser	ITS performance is based on core engine and HTML program running on ECC system

ITS is ABAP applications on mobile devices that has following advantages:

• The entire application can be developed using ABAP workbench.
• SAP GUI can be used for Windows to perform ABAP debugging and system landscape is not complex.
• The templates and generated HTML can be custom as per business requirement.
• HTML or JavaScript can be used as per device types in application.

3.0  Step By Step Procedure for developing ITS templates

Go to transaction SE80

Choose Internet service from drop down

Figure 1

Enter a service name and hit enter or click on the  icon to create a new Internet service.

Figure 2

Once yes is clicked the following pop up will appear

Figure 3

Provide the Transaction code for which the ITS service is to be created. The transaction should involve screen programming (Module pool programming)

           

           

Figure 4

            Provide the transport number and the required package to save the internet service.

  

Figure 5

You can now see that the topic 99, which is the theme and is automatically created. Double click on the service name and enter the following in the parameters.

Enter the service name in ~SERVICE parameter and T-code in ~TRANSACTION parameter

Figure 6

Once this is done, expand the tree to reach the HTML templates and right click on that to create a HTML template.

Figure 7

Enter the theme as 99, enter the module pool program name and screen and choose without HTML tables in drop down and save.

Figure 8

NOTE: Create HTML templates for all the required screens in the transaction call.

For example in below screenshot you can see that the following required screens for the transaction call is created and the HTML template is auto generated

Figure 9

Finally when all the screens are developed right click on the service -> publish and complete service

              

Figure 10

This completes the creation or internet service of the module pool program. Next step is to create the ICF service in SICF transaction.

4.0 Creating an ICF service

Execute the transaction SICF.

Figure 11      

Navigate to the path default_host/sap/bc/gui/sap/its/test/mobile/itsmobile01/ and right click and select ‘New sub-element’.

Figure 12

As soon as you click on the new sub element, the following pop up will appear. Just click ok and proceed.

Figure 13

Next step is to provide an internet service name. Here you can choose to create an independent service or you can create referring to the existing internet service.

               Figure 14

Once the above step is done, you’ll be taken to configuration page where you need to configure the service for various section. Give the service a description in any one descriptions.

1. 1.       Service data.

Change the value in the interactive options- GUI link, from not specified to yes and click on GUI configuration.

                  

                   Figure 15

          In the following pop up add the following entries as entered in the internet service in SE80.

                

                     Figure 16

1. 2.       Logon data.

Change the procedure from Standard to Alternative logon procedure and remove all the list from procedure other than field’s authentication.

Figure 17

    

Figure 18

      Finally you should have only fields Authentication.

     

Figure 19

1. 3. Handler List.

                Enter the class CL_HTTP_EXT_ITS.

1. 4. Error pages.

                Here choose the first sub tab within the error pages, which is Logon errors and then choose the last radio button System login and click on configuration.

               

Figure 20

 

Change the radio button from Use Global settings to Define service specific settings and add the   following configurations, add class CL_MOBILE_SYSTEM_LOGIN in custom implementation.

        

Figure 21

Next step is to choose the sub tab in error pages, which is log off page and add the service specific URL which is generated automatically for the current service which  you are creating.

Next step is to save the entire service and then come back to right click on the service in the sub element and activate the service and click yes on the TREE icon.

Figure 22

Note: To know the service specific URL, once the service is activated, right click again and test service the browser will launch will the URL, you can copy the same to add it in error pages, logoff page tab.

To test the service you can either do it from SICF service which you created by right clicking and test service or you can go to SE80 where you created internet service
