We are trying to implement a Record Center. For our document sets, we are using the Send Document Set to Repository action. However, it doesn't appear to copy over the workflow history. Is this correct? How can the workflow history be maintained?
Nintex offers some web service methods, you find the reference here: http://help.nintex.com/en-US/sdks/SDK2013/#Reference/SOAP/NW_REF_SOAP_NAV_M.htm%3FTocPath%3DNintex%2...
For example you can use the "GetWorkflowHistoryForListItem" method, to receive all the history for a single list item and save that to a variable in your workflow. You can then use that variable to write back the information to the document set, another list, send it by mail or do whatever you think is most appropriate.
Let us know how this advice works out for you, Alisa Smith! Thanks!
