Migration of
Existing ITS Services 
Use
This guide
describes the steps required to make existing Internet Transaction Server
services (ITS services) – the Internet Application Components (IACs)
– executable after migrating them into an SAP Web Application Server
6.40 with integrated ITS.
This
situation occurs when you have developed your own IACs, which were executed up
to now with a standalone ITS and which are now required to run on the SAP Web
Application Server with integrated ITS.
Note that the integrated ITS does not support Flow Logic and WebRFC applications. These must still be executed with a standalone ITS.
Prerequisites
...
...
1. You have migrated your SAP system, in which up to now the used IACs were executed, to an SAP Web Application Server 6.40.
2.
To better
understand this document, we recommend that you familiarize with transaction
SICF for creating 
Internet Communication
Framework services in the SAP system.
3. You must decide whether you additionally want to use the templates for the integrated ITS on a standalone ITS. If yes, you must pay attention that the desired changes are compatible.
To facilitate compatible development in HTMLBusiness for integrated and standalone ITS, you can use the ITS switch ~icf. This switch is set to 1 for Web AS with integrated ITS.
Example for using the switch in an HTML template:
`if (~icf=1)
<Code for integrated ITS>
else
<Code for standalone ITS>
end`
Procedure
To make an IAC executable with the integrated ITS, perform the following steps:
...
...
2. Set up the ICF service for the ITS service (IAC)
a. Create the ICF service name
b. Create ICF/ITS handlers
c. Activate the ICF service
3. Maintain ITS service parameters
a. Adapt the URL generation in the HTML templates
b. ICF alias concept
c. ICF session ID handling
5. Publish the ITS service
Result
As a result of this procedure, you can now run your ITS service directly with the integrated ITS.
