When ends users try to modify or create a new report, the error "Attempted an unsupported operation." appears:
The problem is caused because DSM Reporter is installed on a remote Agent which has a language different than English configured (for example, Spanish).
Every management component (like DSM Explorer / Reporter) is not supported having Spanish language configured, the only supported languages are: English, French, German and Japanese. Here is the detail of the supported languages:
Client Automation 14.x
In order to solve this problem, the language of the Agent needs to be configured back to English (or any other supported language) running the following command:
ccnfcmda -cmd SetParameterValue -ps itrm/common/localization -pn language -v lang
The value of lang specifies the desired language. Possible values are "enu" (English (U.S.)), "deu" (German), "fra" (French), and "jpn" (Japanese).
