Use
In sales orders, you normally enter the R/3 article number for the product being purchased. For mail order catalog sales, however, you may have article order numbers (item numbers) that are associated with specific product catalogs. For example, R/3 can add the catalog code (source code or product catalog identifier) to the article number according to certain algorithms. This way you can track which catalog, or which pages within a given catalog, generated the sales order.
In Sales Order Processing, these article order numbers are treated exactly like normal article numbers in the R/3 master data. The customer gives the article order number, and the system automatically determines the catalog from which it came.
You can enter either a catalog number or its code at the header level of the sales order. This records what prompted the customer's order (the impulse to buy).
You can also enter a catalog number or code at the line item level. If you leave it blank and just enter an article order number, the system will search for the article in the catalog entered at the header level. If the article is not in that catalog, or if no catalog was entered at the header level, then the system will look in the most recent catalog.
Item lines within a sales order can be from different catalogs.

If you want to use article order numbers rather than article numbers, you must first change Customizing settings for sales documents. For each sales document type, you can choose whether sales orders are to use the R/3 article number or the article order number.
