icm/HTTP/error_templ_path 
Use
This parameter is used to set the ICM, in case of errors. You can create your own ICM error pages and in this parameter define the path where the ICM can find the pages.
If the parameter is
not set, the ICM returns a static error page. The section 
ICM Error Handling
explains how the error pages work and how to create them.
You can create
static and dynamic error pages. Here is an example
of a dynamic error page.
Procedure
Once you have created an error page in the file system, set the parameter to the directory with the error template files.
icm/HTTP/error_templ_path = /usr/sap/B6M/D13/data/icmerror
Your error pages will be located in this directory. If no suitable page for the error that occurred is found in the directory, the ICM returns a static error page.
