Hi,

Is it possible to connect a pricelist to a channel somehow? The scenario is that same account can purchase order on both b2c and b2b (which are 2 different channels). The user is connected to a specific group which is in its turn connected to b2b-pricelist. so when user is logged in on b2c-channel he/she gets b2b-pricces which is incorrect. Any ideas how to solve this?

Litium version: _[7.2.0]_

Could you add a decorator for the price calculator method `GetPriceLists` that excludes this price list if it’s the b2c channel?

Untested:

```auto
using Litium.Products;
using Litium.Products.PriceCalculator;
using Litium.Runtime.DependencyInjection;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace Litium.Accelerator.Services
{
	[ServiceDecorator(typeof(IPriceCalculator))]
	public class CustomPriceCalculator : IPriceCalculator
	{
		private readonly IPriceCalculator _parent;
		private readonly PriceListService _priceListService;

		public CustomPriceCalculator(IPriceCalculator parent, PriceListService priceListService)
		{
			_parent = parent;
			_priceListService = priceListService;
		}

		public IDictionary<Guid, PriceCalculatorResult> GetListPrices(PriceCalculatorArgs calculatorArgs, params PriceCalculatorItemArgs[] itemArgs)
		{
			calculatorArgs.PriceListSystemIds = GetPriceLists(calculatorArgs).Select(x => x.SystemId).ToList();

			return _parent.GetListPrices(calculatorArgs, itemArgs);
		}

		public ICollection<PriceList> GetPriceLists(PriceCalculatorArgs calculatorArgs)
		{
			// if channel is B2C, exclude B2B price list
			if (IsB2C()) {
				return _parent.GetPriceLists(calculatorArgs).Where(x => x.Id != "B2BPriceListId").ToList();
			}

			return _parent.GetPriceLists(calculatorArgs);
		}
	}
}

```

That could definitly be a solution, I will test and come back! Thanks Nils!

I just tested this in 2 different ways. But `GetPriceLists()` never gets called? 🤔  
I first tested it by modify `MVC/Routing/PriceCalculatorDecorator` which comes as standard with Accelerator 7.2.0. And then I actually created a custom price calculator located in same path/namespace as in ur example, but still `GetPriceLists()` doesn’t get called. Any idea why?

You should see it called when opening a category for example, since it’s called directly from the price filter service.

That’s also why we call it in `GetListPrices`, to ensure that when calculating a price (for when looking at a product page for example) we use our subset of price lists. Otherwise, when the original calculator calls it, it will use its own implementation. Is `GetListPrices` not called either?

Thank you Nils!! I totaly missed this line 🙂

```auto
calculatorArgs.PriceListSystemIds = GetPriceLists(calculatorArgs).Select(x => x.SystemId).ToList();

```

I changed it and it works as expected now.

One issue that I noticed is when adding some product to the cart from e.g. b2b channel and then visit the checkout page on b2c, the orderrows in the cart will have the prices for the b2b, I hoped they were updated “automatically”, so I need to look into that. 🤔

Do you have the code mentioned here in your `ControllerBase`?

Not sure what the issue could be. I tried in a 7.2.4 with two channels on the same domain (but different prefix), and the call to `SetChannel` will trigger a re-fetch of list prices which would hit your decorator.

I think I found the issue… in `GetPriceLists()` I use `_requestModelAccessor.RequestModel?.ChannelModel?.Channel` to check the current channel and when the call comes from `Cart.SetChannel` (see the stack trace below to see the call stack) the `_requestModelAccessor.RequestModel` is null which cause the issue. I think I will change to fetch the current channel from either the orderCarrier or store it in the http session from ControllerBase.

The call stack:

Try using the `RouteRequestLookupInfoAccessor` instead, it has a property for the channel. `Initialize` is run prior to any filters I believe, so `RequestModel` won’t be set.

Tested it with both `RouteRequestLookupInfoAccessor` and `CartAccessor` and both work fine, but I will go for `RouteRequestLookupInfoAccessor` feels kinda safer 😄

Thanks a lot for ur help, Nils!
