Multiple Entity Derivations in SAP MDG with the help of BRF+

Hello Experts,

If we want to do the cross entity derivations (Not by the Cross Entity BADI) , but with the help of BRF+.

Is this possible?

I tried creating the same in case of Vendor,Tried adding two different entites in the function & written the rules to achieve the same.It was not giving the expected output.

Is there is something which I am missing or Cross entity derivations are not at all possible with the help of BRF+??

Kindly suggest.

Thanks,
