The ICU data directory has already been set to the specified directory that is different to the requested one using a case sensitive comparison. It is not possible to change it to a different directory in the same run unit.
Processing continues. The system ignores the value in the configuration file ICUDATADIR parameter and looks for code page CNV files in first directory that was set by an earlier caller that was not PowerExchange.
Set the ICUDATADIR parameter to be the same as the existing name and copy the code page CNV files to this directory.
