I have a MS Project file uploaded to the document library on the site. I want to create two lists with the information retrieved from this document (Project tasks and Custom list). I need these two lists to be synchronised with the original document, so when I edit either a list or a document, both will be updated. Is it possible?
Yes, the workflow you will be using should be connected to the form in the Library. Then, in SharePoint Desighner when you edit the workflow, you choose which list you want the info to go to ( which could be either a Task list or customized List), and there you can also create your custom columns. To have a second list upload the same information you have to do the parents child aspect listed above.
