Use this parameter to specify if the requirement consideration window related to the product should open automatically or not when entering the product.
When the product category is Normal, this window opens after entering the product reference on the order line.
When the product category is Service, the requirement consideration window opens:

after entering the product reference if the Product type is defined as being Displayedor Hidden. The requirements suggested in the window correspond to the product type defined by default in the DEFITMKND - Default service type parameter (ACH chapter, ORD group),
after entering the Product type, when the Product type is defined as available for entry.

Even if this parameter is set to No, the requirement consideration window automatically opens when the product is of the Subcontract type: in fact, the creation of an order line for a subcontract product can only be made by consuming subcontract requirements.
