Restrictions and limitations

  • The component is designed for work with the following versions of Microsoft SharePoint servers:
    • Microsoft SharePoint Foundation 2010
    • Microsoft SharePoint Server 2010
    • Microsoft SharePoint 2013 Server
    • SharePoint Online (Office 365) Service
  • When the AutoStore Add-on services connection method is used, the component can upload files by using two different methods:
    • Upload with buffering in the memory of the workflow server host machine. In this case, the size of the sent document is limited by available virtual memory on this computer.
    • Streaming upload. This method is used automatically if anonymous access is allowed to the following file: C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\ISAPI\_nsi\NsiUploader.aspx on the SharePoint server host machine.

      In order to allow the anonymous access, in the IIS settings select a desired site, select the _vti_bin/_nsi folder, open Authentication, and set Enable status for Anonymous Authentication.

    Use the most appropriate method for file uploading.

  • If you are uploading big files to the SharePoint 2010 server, you should specify the appropriate size limitation on the SharePoint 2010 server. To make it, go to SharePoint 2010 Central Administration > Manage web application and select your site; then go to General Settings > Maximum upload size and select your own maximum.
  • To work with this component, the user should have at least the 'Contribute' permission level for the specified folder, list, or document library.
  • To use impersonation, the user specified in the User name field should be a site collection administrator. With this option on, the documents and list items will be saved with the permissions of the impersonator.
  • If you use Native services or Office 365 Services connection methods, then the component will use Client Side Object Model to access the server. These methods have the following special restrictions:
    • On the General tab, the Impersonate and Server log file options are disabled.
    • The component should be able to successfully transfer files up to 200 MB in size, but not more.
    • The site list can be got only for the specified site collection.
  • The component supports only the integrated Windows authentication and Forms-based authentication methods.

    The integrated Windows authentication methods rely on IIS authentication for SharePoint 2010 Web applications; the methods are NTLM or Kerberos (IIS Windows Authentication). IIS settings should be checked after the Web application is created: the Windows authentication method should be enabled.

    The Forms-based authentication methods rely on IIS authentication for Claims-based SharePoint 2010 web applications. IIS settings should be checked after the web application is created: the Forms-based authentication method should be enabled.

  • When using multiple level metadata on Microsoft SharePoint 2010, the hierarchy will be displayed on the device panel as a list. However, the tree view will not be displayed. The full hierarchical path is displayed to make the selection of the right metadata easier.
  • The Native Services connection mode supports only SharePoint 2013 Workflow.
  • For a proper operation of the component, Windows Identity Foundation (WIF) for .NET Framework 3.5 version should be installed on the machine, where workflow server is running.
  • The component is not able to retrieve and show more folders than the number specified in the List View Threshold field in the General settings of a web application on the SharePoint site. By default, this number is 5000.
    Note: You can check the number specified for the selected web application by the following path: (SharePoint 2010) Central Administration >> Application Management >> Manage Web Application >> web_application >> General Settings >> Resource Throttling >> List View Threshold, where web_application is the name of a web application on the SharePoint site, for which you want to check the threshold.
  • Use of External Data fields has its additional number of restrictions that can be found in External Data field restrictions.
