Cognos 8.4 dill through Cube to Relational

[pz]

Hi all,
After migration from 8.2 to 8.4. We have difficulties with a drill through report.
Drill through from Cube to Relational riport.
We would like to pass the memberCaption and a businessKey for a member.
I have set two parameters for the target report and
set these on the source.
Property to Pass : membercaption and businesskey.
On the target there is a simple list showing the parameters, but I get an error message.
e.g.
PCA-ERR-0009
The Member Unique Name (M-U-N) needs to start with '[':""

Many Thanks

I have solved the issue.

I had to use short names, because the cognos could not recognize the two parameters.

eg: pKtsgncs1, pKtsgncs2 does not work, but pKcs1, pKcs2 works.
