Report import - Dok-X

Hi,

Was trying to import report through tcode: cg3z / cg36 .

Getting following error:

Assigning values to characteristics to from class SAP_EHS_IBD_SDS failed.

Writing additional data from key file *.pdf.key failed

Have checked the class : SAP_EHS_IBD_SDS, it is with class type 017. Is it correct?

File being imported are in PDF format.

Key files used to upload and import is having extension *.pdf.key and transfer format used is BIN.

What could be wrong with import process?

Thanks in advance.

Regards,

Niraj
