OFUP and Derivation Rules - Conflict

Hi Experts,

I am facing one strange issue while calling following Table Lookup:

This Table Look up is perfectly working and calling accurate Valuation Class while creating Material Reservations if i am using OFUP Configuration (MM Invoice Receipt under GR/IR Update Tab) but as soon as as i change this config  to (GR and Inv.), this table lookup stops working and it does not populates Plant & Valuation Class therefore i am not able to derive relevant commitment item:

Kindly guide if any one have faced this kind of scenario?

Regards,

Zain Bashir
