• The first schema I have named it OrderItems.xsd. Right Click on the Root node and then click on Rename.
• Type Order as the new name, and then press Enter.
• Right Click again and select Insert Schema Node and click on Child Field Element and create two field elements : OrderID, Description.

Now lets create another schema file and call it Purchase.xsd

• Right Click on the Root node and then click on Rename.
• Type Purchase as the new name, and then press Enter.
• Right Click again and select Insert Schema Node and click on Child Field Element and create two field elements : OrderID, Description.

Now that we have two schemas lets now create a new map that will help us tranform the data from one schema to another.

• Right Click on your Project file and select Add > Add New Item. From the templates select map and enter a new name and click on Open. I like being a little too descriptive hence I have entered the name of the map as "OrderItems_To_Purchase_map.btm". This helps me remember which is the source and the destination schemas. OrderItems here is the source and we are transforming the data to the Purchase schema which is the destination schema.

Now that we have our map opened in the BizTalk mapper. You will notice the left hand side as the Source Schema and the right hand side as the Destination Schema.

• Click on Open Source Schema and from the Schemas select OrderItems.
• Click on Open Destination Schema and from the Schemas select Purchase.

Now you might have some trouble loading the schemas and it may just show you the Root node. Well you will need to save the schemas inorder for them to load in the mapper, so if you cannot see them loaded in the mapper, click on the orderItems and click Save and do the same for the Purchase schema as well. The bizTalk mapper will sense any changes and will prompt you to reload the schemas.

You should now be able to see your schemas in the BizTalk mapper. Now click on OrderID in the Source Schema and then drag it across the grid to the destination field " OrderID" in the destination schema. Repeat this for the description. The lines that you see show how the fields have been mapped between the source and the destination. Now save your new map.
