I would like to create one sequential approval workflow for a number of document types. Depending on the document type the user may need to select 1, 3, 10 approvers for example. Is this possible with Nintex/SharePoint and if so what could be a best practice?
The one thing I'm hoping not to do is create a spaghetti code workflow that would manage the different document types with varying sequential approvals.
If you have different document types why don't you use content types and have content type reusable site workflow? that way you can have a workflow that relates to the content type and less logic inside the workflow to work out which document type it is and what process to run?
I'm not sure what a content type and a reusable site workflow is. Would you mind explaining in a bit of detail?
here is a good explanation in detail of what a content type is:
basically though, it's a type of document/item with associated metadata, and you create one or more of them in your site and attach to your library. so in your case you would have three content types:
document type 1: name, approver 1
document type 2: name, approver 1, approver 2, approver 3
document type 3: name, approver 1, approver 2, ..., approver 10
then you would create 3 x reusable workflow template with nintex - settings > nintex workflow 2013 > create reusable workflow template.
workflow 1 would be associated to content type "document type 1" and would only have one stage of approval
workflow 2 would be associated to content type "document type 2" and would have three stages of approval
workflow 3 would be associated to content type "document type 3" and would have ten stages of approval
if you can give me any more information from what you are actually doing I can mock up some examples for you at some point.
I also found this article that shows how to put an approval request into a For Each loop. Very interesting....
