CRMDiscount.UpdateAndRetrieve Method
The UpdateAndRetrieve method updates a discount and then retrieves it.
Syntax
[Visual Basic .NET]
Public Function UpdateAndRetrieve(
ByVal Caller As CUserAuth,
ByVal DiscountId As String,
ByVal InDiscountXml As String
) As String
[C#]
public string UpdateAndRetrieve(
CUserAuth Caller,
string DiscountId,
string InDiscountXml
);
[C++]
public: String* UpdateAndRetrieve(
CUserAuth* Caller,
String* DiscountId,
String* InDiscountXml
);
Parameters
Caller
Specifies the identity of the caller. To perform this action, the caller must have the prvWriteProduct and prvReadProduct privileges and access rights on the object to be updated. See CUserAuth.
DiscountId
Specifies the ID of the discount to be updated.
InDiscountXml
Specifies the XML string representing a discount. The XML schema is described by discount.xsd.
Return Value
Returns a String type that specifies the XML data representing the new discount. The XML schema is described by discount.xsd.
Remarks
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}
