Material Determination in BoM sub item

Hi All,

In our current SAP system;

1. In quote if there is BOM material, it won't explode and it shows as one line item i.e BOM header.

2. Now in the BoM for one sub item there is a material determination set up.

Issue:

When i create a order with ref to quote now BoM gets exploded and material determination is NOT taking place, I was told it Is possible to activate determination in reference mode. Any idea how i can activate this?

Note: When I create an order with no reference BOM gets and exploded and materail determination also takes place with no issues.
