Error occured when generating charts

Hi Experts,

Env:BI 4.0 SP2 FP13/linux/db2

We are having almost 10 charts in a report.

When am viewing through launchpad am getting the above mentioned error,same charts is viewable in rich client.

I did adding the visualization servicein APS,after that charts can be viewed by one user id,not al user id.s

Secondly i have created separate APS for only visualization service,after that charts can be viewed through CMC,Not in lauchpad

Some times one user id can see,same user id while trying after sometime unable to view.

Awaiting for your inputs.

Thanks in advance.

Regards,

Selva.
