Assembly Orders with Item Charges?

Last Friday we tried to do assembly orders based on raw materials. Currently though we send out the items to be processed/mixed so there are service fees. I set them up as Resources in which seems to be separate from the unit costs of the finished good. I'm not sure since there is no way to assign these charges as in with purchase order/invoices. Also at the same time, we need to pay this out to a 3rd party so we need to set this up as its own PO/PI? Then in this way does the assembly order include the resource costs into the unit costs since the system pays this item charge separately (need to make Purchase Invoice)?

Our current system does this in one step called a Process Purchase Order where it balances the inventory, let's you enter the exact quantities used (which BC is off by decimals), and then creates a bill for the service fees.

Thanks.

As far as I know, this will be factored into the cost.

Let me give you a simple example.

I created a completely new item (Cost Test) with no cost.

Create an Assembly Order with one Resource line and post it.

Assembly Order Statistic:

Cost:

Hope this helps.

Thanks.

Typically for these types of service fees you would use a resource as you have been doing. And not a business central item charge.

There are two steps:

1. You would include the resource on the assembly bom line, because of this the system will include the resource cost as part of the finished good cost.

2. You would then separately invoice the resource on a purchase order/invoice so you can pay the vendor. There is no connection by the system between using the resource on the assembly order and the invoicing, you need to do this part manually. To keep track of how much you need to invoice the vendor for this resource, you can simply look at the Resource Ledger Entries, you will have a tally of all the times the resource was used on an assembly order.

item charge like freight is assigned on purchase order to items, which roll up to finished product. however, assembly only incorporate items, resources into assembled item.

this is seen as a simple form of manufacturing. If you outsource to outside vendor to process, BC doesn't have function to roll up those costs to assembled items.

you could create PO to keep the costing, which is separate from the assembled items.

If user runs BC on premium version, which has full manufacturing module, this is handled by subcontracting in which vendor is linked to a work center and BC create PO linked to the production order for cost management
