Access ProcessId and StageId in Dynamics CRM Plugin

Question

I'm writing a plugin on Campaign which used a Business Process Flow. The fields ProcessId and StageId which are created by the Business Process Flow in Campaign Entity. I need to retrieve these values for a record in my plugin.

They don't appear in the Plugin Registration Tool's Step Image. They don't even appear in CRM workflows were I can populate them in some other field.

Is there a good alternative on how I can achieve this?

Answer 1

You should be able to retrieve this by passing the correct input parameters to a workflow activity in this business process flow.

1) if you have these string inputs:

[RequiredArgument]
[Input("Process Name")]
public InArgument Process { get; set; }

[RequiredArgument]
[Input("Process Stage Name")]
public InArgument ProcessStage { get; set; }

2) Execute code Get Process:

using (var _context= new OrganizationServiceContext(service))
{   
   // Get the processid using the name provided
   var process = (from p in _context.CreateQuery()
                  where
                  p.Name == Process.Get(executionContext)
                  &&
                  p.StateCode == WorkflowState.Activated
                  select new Workflow
                  {WorkflowId = p.WorkflowId}
                 ).FirstOrDefault();
   if (process==null)
       throw new InvalidPluginExecutionException(string.Format("Process '{0}' not found",Process.Get(executionContext)));

Get the stage id using the name provided

var stage = (from s in _context.CreateQuery()
             where
             s.StageName == ProcessStage.Get(executionContext)
             &&
             s.ProcessId.Id == process.WorkflowId
             select new ProcessStage
             {ProcessStageId = s.ProcessStageId}
            ).FirstOrDefault();
if (stage == null)
    throw new InvalidPluginExecutionException(string.Format("Stage '{0}' not found", Process.Get(executionContext)));

You can now Change Update the stage with your values retrieved ...

Entity uStage = new Entity(context.PrimaryEntityName);
uStage.Id = context.PrimaryEntityId;      //
uStage["stageid"] = stage.ProcessStageId; //retrieved stage 
uStage["processid"] = process.WorkflowId; //process id
