SharePoint 2013 – Page 8 – Nishant Rana's Weblog

Hi,

I was getting the “appweburl” is undefined error while developing a SharePoint Auto Hosted App.

// Initialize the RequestExecutor with the app web URL.

executor = new SP.RequestExecutor(appweburl);

//Get the URI decoded URLs.

hostweburl =

decodeURIComponent(

getQueryStringParameter(“SPHostUrl”)

);

appweburl =

decodeURIComponent(

getQueryStringParameter(“SPAppWebUrl”)

);

The value of hostweburl was getting passed in the querystring properly, but the value for appweburl was not getting passed.

The way to resolve this issue was to add an empty element to the App.

By default the Autohosted or Provider-hosted template have an empty app web. If the app web is empty SharePoint doesn’t create the app web for you.

That’s how simply adding an empty element fixes the issue.

The post that came to rescue.

Hope it helps.

For import to work we will first define our WCF Service.

We could refer to this post first on how to define and use the WCF Service.

https://nishantrana.wordpress.com/2013/06/13/integrating-crm-2011-and-sharepoint-2013-using-bcs-wcf-service-crud-operation/

Here as we are not going to perform update, delete or create operation we don’t have to implement those methods.

Here we would be defining only Read Item, Read List and IdEnumerator Operation of BCS.

IdEnumerator method enables external data search in SharePoint and will be used while defining new profile synchronization connection.

For our scenario we have created a custom entity named Lawyer in our CRM System. These Lawyers are SharePoint user (AD User)

 string[] GetLawyerLoginIDs();

[OperationContract]

Here instead of taking Guid of the record we will be taking LoginId (login name of the AD User) of the user as the unique identifier in our BCS, because the same will be used for while defining user profile synchronization with the BCS. The login name of the users and SAMAccountName in the AD will be the connection point between the two. The records in CRM will be identified by the login name of Users in SharePoint.

Here after implementing the Interface and after publishing the service, here we will again create the External Content Type based on it and will define the operations Read List, Read Item. This time we will use the User’s Login Id as Identifier.

Next open the User Profile Service Application à Manage User Properties in Central Administration Site of SharePoint.

Create a new user property named User Login ID (Lawyer Login Id here in our case) that imports the value from SAMAccountName property of the AD. (Note: AD Profile Synchronization Connection should already be set up for the user’s profiles)

Create a new Synchronization Connection for importing profile from BCS

Define the synchronization connection based on Lawyer Login ID property

Create few more user properties e.g. one for Practice Detail field and other for Lawyer Availability field defined as Data Member in the contract in our case.

Open User Profile Application à Manage User Properties

Create a new property named Practice Detail of type String that imports the value from the PracticeDetail attribute of the BCS connection defined.

Create one more property name Next Availability of type date time that imports the value from the LawyerAvailability attribute of the BCS connection defined.
