Sample: Export and Import a Data Map

[Applies to: Microsoft Dynamics CRM 2011]

This sample code is for Microsoft Dynamics CRM 2011, and can be found in the following location in the SDK download:

SampleCode\CS\DataManagement\DataImport\UsingExportAndImportMappings.cs

SampleCode\VB\DataManagement\DataImport\UsingExportAndImportMappings.vb

Requirements

For more information about the requirements for running the sample code provided in this SDK, see Use the Sample and Helper Code.

Demonstrates

This sample shows how to create an import map (data map) in Microsoft Dynamics CRM, export it as an XML formatted data, import modified mappings and create a new import map in Microsoft Dynamics CRM based on the imported mappings.
