Find instance based on value in the pipeline

Question

In my current project I need to check if a process Instance already exist. I should be able to check this against a value which is stored in the pipeline. In WmMonitor I tried a few services but with none I was able to find the existing process.

Do I need to mark the pipeline variable as logged field to be able to find the process instance?

Mayeb someone can share an example?

How you want to use that? Why you need to check that? Why is it bad to have more process instances? — Betlista, Jan 25 '16 at 15:02

Yes, you have to mark the field as a 'logged field' in order to be able to search for process instances with a certain value in this field. Use services from the package WmMonitor.

This is too long, so I used answer instead of comment.

As of my understanding, you have some data, for simplicity assume, that just one string represents the data. Let say this is in a DB table. You should have flag in same table - processed with values true/false (in DB typically 0/1) and there should be a scheduler creating processes for unprocessed data only.

So the pseudo code would be:

retrieve unprocessed data
    for each record try to create process
    if creation was successful, mark the data as processed and continue

in this scenario you do not need to check whether process was started already...

Feel free to comment if something is unclear ;-)
