How to keep BatchID consistent?

DungVu

Currently in our data model has a field called BatchID and the value was populated with script "Folder.Batch.ID" at Default Value Expression. However, When the batch was spawned to new process then the Batch got a new BatchID. At first we tried to use the batch name but the batch name can be duplicates.

Is there a way to keep track of the batch with unique identifier?

Thanks

Yes use a batch processing script to assign the value without the default value expression. 

Here is an example of what it should look like 

  Private Sub BatchProcess_BatchCompleted(sender As Object, e As BatchProcess.BatchCompletedEventArgs) Handles BatchProcess.BatchCompleted

        Select Case e.StepCompleted.Name

            Case "Scan"

                Try

                    Dim CurBatch As Batch = e.Batch

                    Dim myFolder As BatchFolder = CurBatch.BatchRoot

                    Dim di As DocumentInstance = myFolder.IndexData

                    Dim fi As FieldInstance = di.Fields("Batch_ID")

                    e.Batch.Name = e.Batch.Name + " " + e.Batch.Id.ToString

                    fi.Value = "hello"

                    fi.Root.Database.SaveChanges()

                Catch ex As Exception

                    Grooper.WriteToEventLog(EventLogEntryType.Error, ex.Message, e.Batch)

                End Try

Stotelli, Should I put script in an unattanded activity?

DungVu

I put the script in the ProcessingScript but my index data is not updated with new value using fi.value = "Hello"

DungVu

Can I run update the Index data field with the new value within the process script? Do I need to use the Data Instances? Please give me some direction how to build this. Thanks
