使用Workflow Dynamics CRM 2016更改BPF阶段

Question

We are currently on Dynamics 2016 on premise. We are following this article to set up a workflow to change the Stage on one of our business process flows. The setup of our BPF is below. We are receiving the following error when the BPF runs. I've narrowed this error down to somewhere in the Update Contract Setup Stage step. What are we missing here? Perhaps we are trying to do something only available on D365? Other attempts at changing the stage on a BPF include using the Web API (issues detailed here ) and using a trigger to set the database values (yes, we know this is not supported).

Workflow Setup

Update Contract Setup Step

Answer 1

I'm not sure if you can do this directly, but i used in the past Dynamics Workflow Tools which have a lot of functions which you can call from a workflow. For BPF Stage you can use "Set Process Stage" Method.
