Value Range and Syntax
The parameter can have the values TRUE or FALSE. The default value is TRUE.
The parameter affects the contents of the error pages of the ICM or SAP Web dispatcher, as follows:
TRUE: The error page also contains details about the cause of the error (name of the application server, date, module, line, component, description of error).
FALSE: Here there are no details. With some errors an error tag is issued, which you can use to find the error details in the trace file (dev_icm or dev_webdisp) For example, tag: {00060025}
SAP Recommendation
For security reasons the details should not be made available to Internet users. For this reason SAP recommends you set the parameter to FALSE. If the details are not critical to security, you can leave the value as TRUE, as the details can be useful for finding errors.
Integration
If you configure error pages dynamically (see ICM Error Handling and Example of a Dynamic Error Page), this overrides the default error pages. In that case the value of this parameter is irrelevant.
