Orphan error, in error profile

Normally, I would set the Folio value to some unique value.  e.g. The process name followed by a unique number or the datetime string.  So for a Leave Request process, it might be LR-002345 or LR-1500608-1354.

This will allow you to easily search for the instance you are working with.

I need this for an infopath workflow.  Where would you put this logic?

Okay I created a Server event at the beginning of the workflow which get's the identity created for the row created in the database, then did the following for the folio in the event.

// code that get's Id from table in db 

K2.Synchronous =

// Folio already has some metadata defaulted/set in the designer, so appending the Id

K2.ProcessInstance.Folio += string.Format(" - {0}", Id);

If the data you wish to include witin the Folio resides within the XML of the InfoPath form, you can do this directly from the InfoPath Properties Wizard (see attached screenshot)
