BizMerchant.RetrieveBusinessHierarchy Method

The RetrieveBusinessHierarchy method retrieves all business units (including the specified business unit) in the business unit hierarchy.

The returned child business unit XML data is not in the hierarchical format. Instead, it is a flat format, as shown in the following example:

Business hierarchy:

        B 
     /     \ 
    B1      B2 
   / \      / \ 
 B11 B12  B21 B22 

Returned XML data:

<BusinessUnits>
   <BusinessUnit>
      ...// B1 fields
   </BusinessUnit>
   <BusinessUnit>
      ...// B2 fields
   </BusinessUnit>
   <BusinessUnit>
      ...// B11 fields
   </BusinessUnit>
   <BusinessUnit>
      ...// B12 fields
   </BusinessUnit>
   <BusinessUnit>
      ...// B21 fields
   </BusinessUnit>
   <BusinessUnit>
      ...// B22 fields
   </BusinessUnit>
</BusinessUnits>

Syntax

[Visual Basic .NET]
Public Function RetrieveBusinessHierarchy(
  ByVal Caller As CUserAuth,
  ByVal BusinessId As String,
  ByVal ColumnSet As String
) As String
[C#]
public string RetrieveBusinessHierarchy(
  CUserAuth  Caller,
  string  BusinessId,
  string  ColumnSet
);
[C++]
public: String* RetrieveBusinessHierarchy(
  CUserAuth*  Caller,
  String*  BusinessId,
  String*  ColumnSet
);

Parameters

Caller

Specifies the identity of the caller. The caller must have the prvReadBusinessUnit privilege to perform this action. See CUserAuth.

BusinessId

Specifies the ID of the business unit. This ID is specified by the platform and obtained at creation time.

ColumnSet

Specifies an XML string describing the fields you would like returned for each child business unit. Passing "" or null returns all columns. The XML schema is described by businessunit.xsd. See also ColumnSetXML Schema.

Return Value

Returns a String type that contains the XML data listing all the business units. The fields that are returned for each business unit depend on what fields are specified in the ColumnSet parameter. The XML schema is described by businessunit.xsd.

Remarks

If there is an error, SOAP throws an exception and the error message is reported in System.Web.Services.Protocols.SoapException.Detail.OuterXml.

All IDs passed to the platform are GUIDs wrapped in braces. For example: {6522D89A-A752-4455-A2B0-51494C6957C3}

Example

[C#]
// It is assumed that the caller has the privileges to perform this action
// strServer should be set with the name of the platform Web server
string strServer = "myservername";

// virtualDirectory should be set with the name of the Microsoft CRM
// virtual directory on the platform Web server
string virtualDirectory = "mscrmservices";
string strDir = "https://" + strServer + "/" + virtualDirectory + "/";

// BizUser proxy object
Microsoft.CRM.Proxy.BizUser bizUser = new Microsoft.CRM.Proxy.BizUser ();
bizUser.Credentials = System.Net.CredentialCache.DefaultCredentials;
bizUser.Url = strDir + "BizUser.srf";

// BizMerchant proxy object
Microsoft.CRM.Proxy.BizMerchant merchant = new Microsoft.CRM.Proxy.BizMerchant ();
merchant.Credentials = System.Net.CredentialCache.DefaultCredentials;
merchant.Url = strDir + "BizMerchant.srf";

string strErrorMsg;
try
{
   Microsoft.CRM.Proxy.CUserAuth userAuth = bizUser.WhoAmI();

   // Set up the columns that you want to retrieve
   string strColumnSetXml = "<columnset>";
   strColumnSetXml += "<column>businessunitid</column>";
   strColumnSetXml += "<column>name</column>";
   strColumnSetXml += "</columnset>";

   string strResultXml = merchant.RetrieveBusinessHierarchy(userAuth, userAuth.MerchantId, strColumnSetXml);
}
catch (System.Web.Services.Protocols.SoapException err)
{
   // Process the platform error here
   strErrorMsg = ("ErrorMessage: " + err.Message + " " + err.Detail.OuterXml + " Source: " + err.Source );
}
catch (Exception err)
{
   // Process other errors here
   strErrorMsg = ("ErrorMessage: " + err.Message );
}
