Double byte language i.e Japanese or Chinese text in non Unicode System


I have translated text into Chinese and Japanese in a Unicode system and want to move it into a non Unicode system. Would Chinese/Japanese characters display correctly in a non Unicode system when moved from Unicode system. I am doing translation in ECC60 or SAP 4.7 Unicode system and moving to SAP 4.7 non Unicode system.

    Hi Balakrishna,

    in general the transport between Unicode and Non-Unicode systems is supported.

    However there are restrictions, which are outlined in SAP note 638357.

    In your case it is a prerequisite that the objects to be transported are language dependent (text lang. flag is set on the language key - see SAP note 480671) and the languages are properly setup in the target systems.

    For double byte data there is a specific issue when transferring data from Unicode to Non-Unicode:

    In a Non-Unicode system, one double-byte character needs two bytes, therefore e.g. in a 10 char field, 5 double byte chars are fitting. In a Unicode system, you can insert 10 double-byte chars in a 10 char field. Hence there is a risk of truncating characters in case of Unicode --> Non-Unicode communication.

    Please also have a look at SAP notes 1322715 and 745030.

    Best regards,
