As of Release 4.6 you can use project stock in conjunction with assembly processing.

If you do not create these objects in Customizing, you should use sales order stock with assembly processing. As with project stock, you can decide whether this stock is valuated or nonvaluated.

Valuated stock is stock in which every material is managed on a both a value basis and a quantity basis. All goods movements for the make-to-order stock trigger corresponding postings in the stock accounts in Financial Accounting.

Non-valuated stock is stock where each material is managed on a quantity basis only, without being valuated directly in money terms. Goods movements in make-to-order stock are not valuated and do not give rise to postings in Financial Accounting. The value of the stock is calculated in total at the period end by results analysis; the calculated values are then transferred to Financial Accounting.

You determine whether the sales order stock is valuated or nonvaluated in the requirements class, which you maintain in Customizing for the Project System (Project System ® Material ® Control of Sales-Order-Related Production ® Check Requirements Classes).
