Problem
When you have upgraded from SmartPlant Foundation 2016 (6.0) to the latest version SmartPlant Foundation 2019 (10.0) or earlier, and use the GetWorkflowStepsForUserAtStatus method definition to return workflow items for a user, the following error appears:
NotImplementedException
Any previous customization done in SmartPlant Foundation 2016 (6.0) using the GetWorkflowStepsForUserAtStatus method definition is broken after upgrade as the method no longer exists in later versions.
Solution
The GetWorkflowStepsForUserAtStatus method definition is deprecated from SmartPlant Foundation 2016 (6.1) and was replaced with the GetToDoList method definition implemented to take full advantage of the new DAL that was developed to improve performance.
If you were using the GetWorkflowStepsForUserAtStatus method definition before the upgrade, you will have to modify any custom code to use the GetToDoList method definition.
The only difference is that the GetToDoList method definition returns all workflow
steps that are in a Ready to start status, whereas the GetWorkflowStepsForUserAtStatus method definition returned workflow
steps in any status.
