I have a challenging task on my hands and I can't find resources about it anywhere. You are my only hope.
Here's the task:
I have an approval workflow for the company's contracts and I made its coversheet by using SSRS (basic stuff: who approved when, etc) filtered by the document's Title for the moment (I fancy the idea of switching to the internal ID). I need to make the SQL Server Reporting Services Report generate automatically in the workflow (using the "Title" field as the parameter with which to filter) and get it sent to the printer.
Did you manage to find a solution for this? I'm stuck on the same thing. In my case I generate the SSRS report on a Company letterhead which is then emailed to a store containing info based on Workflow outcomes.
There are few option to generate the PDF/Word from SSRS report in Nintex.
Firstly you can call the SSRS Execute web service and call render method which return byte.
But I have used the SSRS report subscription method "CreateSubscription" which you can specify the report parameters, also define the delivery method of the report e.g store in SharePoint document library or Email.
This is the easiest solutions I have used.
