Error when defining successor of node in workflows

Hi Experts,

I am receiving an error which says "error when defining successor of node XYZ". However in my workflow template, this particular XYZ node does not exists.

Also I found one entry in SWP_SUSPEN table for the main workflow. I tried to execute the report manually RSWWERRE. Still it did not work out.

I also tried to use transaction SWF_ADM_SUSPEND. However my workitem is not showing in the list.

Kindly help me in this issue.

Thanks

Gopal
