Hi Dhruv,
As i check from the technical side and backtrack , I can say that there is a possibility of showing only the valid related products in a BOM explosion case.
The dates are validated in comparison with the validity date of the relation between products which you have to map with one of the date types on the item, which you can do under :
SPRO > CRM > Financial services > Basic functions > Product > Date Type for Product Bundle Explosion , please also go through the documentation here, for further clarifications.
