The mapping variable value that the Integration Service saves in the repository is not compatible with the repository code page.
For example, the repository uses the ISO 8859-1 Latin1 code page and you configure the Integration Service to relax code page validation. If the mapping variable value contains Japanese character data, such as JapanEUC, the saved mapping variable value in the repository could be incorrect. There could be data loss converting from the JapanEUC code page to the Latin1 code page. Make sure the saved mapping variable value is two-way compatible with the repository code page. To ensure the Integration Service can write all metadata to the repository, use 7-bit ASCII characters for all repository metadata or use UTF-8 for the repository.
The parameter file contains characters that are not compatible with the Integration Service code page.
The Integration Service interprets the data in the parameter file using the Integration Service code page. For example, the Integration Service uses the ISO 8859-1 Latin1 code page and you configure the Integration Service to relax code page validation. If you create a parameter file and use Greek character data, such as ISO 8859-7, the value the Integration Service reads from the file could be incorrect. There could be data loss converting from the ISO 8859-7 code page to the Latin1 code page. Make sure the characters in the parameter file are a subset of the Integration Service code page.
