Sales Order Type "Kit" in GATP

Hi All,

It is possible to use Sales Order type Kit to make availability check?

Example:

Item: Inital Kit

Childs: Mat A, Mat B and Mat C.

When I input this Inicial Kit, yours childs are generated, but the system do not check the availability.

I need that the system makes this check, through the GATP.

To another materials (without kit), the system make this check, through the GATP.

Could you help me withi this issue?

Thanks in advance.
