Note I Posted previously on my issue and am still having issues. This post by someone else has my exact same issue. Within a WF I am doing a Create Item. The Doc Library has Unique Permissions and the user has Full Control permission at the library level. The user also has Full Control permission at the Site level.
The user can manually create an item within the library no problem. However after he creates a new item in library A and the Workflow runs to create an item in libraryB he gets a workflow error..."could not creat list item..make sure the list exists and the user has permissions to add items to the list..."
I have the exact same permissions yet the workflow works fine for me...how is this possible..
Also, note we do not have the ability within Workflow settings to do an impersonation step via an Action Set.
Lastly in the create new item (Doc Library) within the workflow I do have a Document Type selected other than Document. The Content Type contains an Excel template. I see the Excel template is within the Forms path of the Doc Library. I assume since he has Full control access at the site level then this would be a non -issue in the event you need special type of permissioning for Content Types.. Really struggling on this one..
