SQL Function To Return Workflow Approval Status

If you have been paying any sort of attention, you will know that I do quite a lot of work with the Workflow 2.0 module of Microsoft Dynamics GP.

We have created a number of reports in the past which allows the status of transactions or card going through a Workflow Approval process; to simplify matters somewhat, I created a SQL function which can be called with the Workflow Type Name and the Workflow Business Object Key and have the approval status returned.

CREATE FUNCTION dbo.uf_AZRCRV_GetWorkflowApprovalStatus(@WorkflowTypeName CHAR(50),@WfBusObjKey CHAR(200))
	RETURNS VARCHAR(14)
AS

This view can be called from a SmartList created using either SmartList Designer, SmartList Builder, via a Reporting Services or Excel Report or any other type of report.

Updated 09/02/2022 – Added the highlighted clause which is needed to filter out no action required status after final approval (thanks to Calum for the reminder).
