CRMDiscount.RetrieveByObject Method
The RetrieveByObject method retrieves all discounts that are associated with an object (discount type).
Syntax
[Visual Basic .NET]
Public Function RetrieveByObject(
ByVal Caller As CUserAuth,
ByVal Object As CObjectName,
ByVal ColumnSetXml As String
) As String
[C#]
public string RetrieveByObject(
CUserAuth Caller,
CObjectName Object,
string ColumnSetXml
);
[C++]
public: String* RetrieveByObject(
CUserAuth* Caller,
CObjectName* Object,
String* ColumnSetXml
);
Parameters
Caller
Specifies the identity of the caller. To perform this action, the caller must have the prvReadProduct privilege and access rights on the objects being retrieved. See CUserAuth.
Object
Specifies the object (discount type) for which discounts are to be retrieved. See CObjectName.
ColumnSetXml
Specifies the XML string describing the set of columns to be retrieved. Passing an empty string or null returns all columns (Nothing or "" in VB .NET). You can find the valid column names in discount.xsd. See also ColumnSetXML Schema.
Return Value
Returns a String type that specifies the XML data representing the new discount. The fields that are returned depend on what fields are specified in the ColumnSetXml parameter. This XML string is in the format
<discounts> + discount1..N + </discounts>
where the XML schema for each discount is described by discount.xsd.
Remarks
Unlike the Retrieve method, the XML string returned from this method may contain multiple objects. If no objects are returned the method simply returns an XML document for the object type with no data.
The XML string returned from this method does not contain elements for fields where the value is null or contains empty strings. This improves performance by not sending more XML data than is necessary from the server to the client.
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#]
// 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.Platform.Proxy.BizUser bizUser = new Microsoft.Crm.Platform.Proxy.BizUser ();
bizUser.Credentials = System.Net.CredentialCache.DefaultCredentials;
bizUser.Url = strDir + "BizUser.srf";
// CRMDiscount proxy object
Microsoft.Crm.Platform.Proxy.CRMDiscount discount = new Microsoft.Crm.Platform.Proxy.CRMDiscount();
discount.Credentials = System.Net.CredentialCache.DefaultCredentials;
discount.Url = strDir + "CRMDiscount.srf";
string strErrorMsg;
try
{
Microsoft.Crm.Platform.Proxy.CUserAuth userAuth = bizUser.WhoAmI();
string strDiscountTypeId = "{48EAEC97-AK9E-6671-9022-7DKCFBD0F0E3}";
// Set up the columns that you want to retrieve
string strColumnSetXml = "<columnset>";
strColumnSetXml += "<column>lowquantity</column>";
strColumnSetXml += "<column>highquantity</column>";
strColumnSetXml += "</columnset>";
Microsoft.Crm.Platform.Proxy.CObjectName objName = new Microsoft.Crm.Platform.Proxy.CObjectName();
objName.Id = strDiscountTypeId;
objName.Type = Microsoft.Crm.Platform.Proxy.ObjectType.otDiscountType;
// Retrieve discounts by object
string strResultsXml = discount.RetrieveByObject(userAuth, objName, 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 );
