Export to Excel

Hello Team!

question regarding export to Excel.

We use api_datasource.printtoexcel procedure to export the results of the dataset.

When we pass the Latin file name to the parameter - all goes smoothly (like "result.xls").

But when we try to pass the Russian one - we get a "zero" file name after export (the whole file name = "xls").

We did some debug and the value in Russian is being passed (it is not null).

The code we use for export (the version is still 1.6 for this installation):

 api_datasource.printtoexcel('V_FS_CNTRL_LIST_EXCEL1', vColumns, 'N',
    api_datasource.getColumnValueTX('ds_sb_cnfl_FS_UPL_FILES.FILE_NAME'),
    api_datasource.FILE_FORMAT_XLS);

Here are the NLS parameters:

NLS_LANGUAGE AMERICAN
NLS_TERRITORY AMERICA
NLS_CURRENCY $
NLS_ISO_CURRENCY AMERICA
NLS_NUMERIC_CHARACTERS .,
NLS_CHARACTERSET CL8MSWIN1251
NLS_CALENDAR GREGORIAN
NLS_DATE_FORMAT DD-MON-RR
NLS_DATE_LANGUAGE AMERICAN
NLS_SORT BINARY
NLS_TIME_FORMAT HH.MI.SSXFF AM
NLS_TIMESTAMP_FORMAT DD-MON-RR HH.MI.SSXFF AM
NLS_TIME_TZ_FORMAT HH.MI.SSXFF AM TZR
NLS_TIMESTAMP_TZ_FORMAT DD-MON-RR HH.MI.SSXFF AM TZR
NLS_DUAL_CURRENCY $
NLS_COMP BINARY
NLS_LENGTH_SEMANTICS BYTE
NLS_NCHAR_CONV_EXCP FALSE
NLS_NCHAR_CHARACTERSET AL16UTF16
NLS_RDBMS_VERSION 11.2.0.4.0

What could you suggest to change or use as a workaround? Seems to be something simple like alter some session params.

Any ideas would be highly appreciated.

Thank you
