Commerce Server 2009 multi channel foundation example

2010-06-10T17:43:00Z

Lately I've returned playing a bit with CS2009 for a POC which meant to show how easy it is to interfere with the Commerce server processes and integrate them with backend systems.

We needed to show integration with external profile (login in the commerce environment and get some information from external resource) and calculation of the basket in external system (This is probably better doing in the basket \ total pipelines , but I wanted to play with the multi channel a bit).

First, we needed to extract information from external web service regarding the logged in user.

I've looked at this whitepaper which gives good example on how to achieve the profile integration :

Then we needed to manipulate the items which are inside the orderform of the user basket.

To do so, we wrote a class which inherits from OperationSequenceComponent.

Override the Execute method

public override void Execute(CommerceOperation operation,

OperationCacheDictionary operationCache,

CommerceOperationResponse response)

Next, retrieves the ordergroups from the operation cache.

OrderGroupCollection cachedOrderGroups = OrderGroupCache.GetCachedCommerceServerOrderGroups(operationCache);

Get the basket (at least try to)

CommerceEntity entity = operation.TryGetSearchModel("Basket");

if (((entity != null) && entity.ModelName.Equals("Basket")))

Now loop over the ordergroups and apply changesas needed

foreach (OrderGroup group in cachedOrderGroups)

{

if (group is Basket)

{

//create new line item

LineItem line = new LineItem("Adventure Works Catalog", "AW053-10", "37", 2);

//override some properties sa this code will run after the basket //pipline

line.ExtendedPrice = 23;

line["_product_Image_filename"] = "abc.png";

//or add new discount to the line item

DiscountApplicationRecord disc = new DiscountApplicationRecord();

disc.BasketDisplayMessage = "this is generated discount";

disc.DiscountAmount = 2;

line.ItemLevelDiscountsApplied.Add(disc);

//add the new line item

group.OrderForms[0].LineItems.Add(line);

//or remove some line prevoise items

group.OrderForms[0].LineItems.Remove(0);

}

}

Now all we need is to place this at the right place in the operation sequence - since I wanted to manipulate the line items , I've put it after the Order Pipelines Processor

Just before the Basket Committer.

One thing that I've notice is that if we remove line items from the basket in the custom operation sequence and place the custom operation before "Line Items processor" component - we get an error

Type : System.ServiceModel.FaultException`1[[Microsoft.Commerce.Contracts.Faults.ItemDoesNotExistFault, Microsoft.Commerce.Contracts, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35]], System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089

Message : The requested item does not exist

The 3^rd component we needed is to export the completed order after payment

In the Execute method, we check: ((string)operation.Model.Properties["Status"] == "ReadyForCheckout"))

And in the forech section we've checked that the OrderGroup is of PurchaseOrder Type

foreach (OrderGroup group in cachedOrderGroups)

{

if (group is PurchaseOrder)

{

writer.WriteFile(group);

}

Pipeline Error: Component Execution failed for component

I've built a custom pipeline component and registered it using the RegAsm /codebase command. Then I've register the component using the commerce server pipereg tool .

After adding the component to one of the pipelines and ensuring that the new component is not "broken", I've reset the IIS and test the component. Since these steps were adequate in commerce server 2002 (my commerce server past experience), I was surprised to get the following error:

"Component Execution failed for component [0x0] hr: 0×80040154 ProgID: XXX Could not create Component XXX. This may be a component registration issue."

I've tried the suggestions found on this blog http://microsoftblog.co.in/commerceserver/pipeline-error-component-execution-failed-for-component/ , but with no luck.

Finally I've put the custom pipeline DLL in the GAC, and that solved my problem.
