Hi All,

Since yesterday sometimes we get this error when we start a process which has an event subprocess: No mapping could be found defining a correlation parameter. All the mappings are set and are correct of course. We use this since years and never had any problem with this. BAW version is 22.0.0. No upgrade or other BAW modificatiom was executed. When we create a new snapshot, but still use the Tip, the process starts whitout any error, but after a while the error comes again.

What's this error? Why do we get randomly this errror? How to solve this?

Any help appreciated,
Thx,

Hi Laszlo,

Try remapping the variables associated with the event sub-process, like first clear the mapping of the UCA, then re-associate the UCA, then do the correlation and other variable mapping, I usually do these steps to resolve the "No mapping could be found defining a correlation parameter" issue.

Thanks!

Hi Atanu,

We did this. After a while the problem comes again. We cannot do this every day...
We replaced the entire event subprocess too, but after a while the error comes again.

Simply unbelieveable. :(

Hi Laszlo,

We have processes and event subprocesses running for more than 5 years and we have never experienced this error. I suspect you have a corrupted component within your process definition (possibly due to a copy paste action). I am sure it's not random as you are perceiving at the moment. It is possible that your corrupted component is triggered only under some conditions.
