Error description

  • CICS will issue INQUIRE_CONVERSION_SIZE with
    SEGMENTED(YES) to convert a chunked web response between CCSIDs.
    If there is a multibyte character caught between two chunks,
    INQUIRE_CONVERSION_SIZE will receive an exception with
    SOURCE_DATA_INCOMPLETE. The conversion from this point on
    finishes successfully, but CICS loses the data which was
    converted prior to the exception.
    
    The application will abend AEXZ.
