Intercompany process

Hi,

In the intercompany or inter-establishment process, is it possible to generate the purchase order with one item and the sales order with another item?

Example: In company FCY01 the article is XXXXX in company FCY02 the corresponding article is YYYYY.

FCY01 is buying from FCY02 it buys article XXXXX, FCY02 sells YYYYYY.
