can't connect from IDT-Relational Connection to BW objects

Hi,

I'm trying to create WebI doc on BW(CUBE or Query) using Relational Connection.

I could create the Relational Connection but the attached error occurred when executing connection test.

Although I recreating APS according to the Note 1690334 (Unable to create or test connection in Information Design Tool),

it didn't work.

Could you tell me the solution?

Kind regards,
Masatoshi
