USMD_RULE in DM- MM (Derive attribute of one entity from the other entity using BRF+ is not working)

Hi Experts,

I have a requirement like one attribute(Tax Classification) of MLANSALES entity needs to be default value from the other entities with some condition from MVKESALES.

which depend on its attribute Sales Organization & Distribution Channel .

I have tried DERIVE_MLANSALES function and in signature tab added these Structure (MLANSALES & MVKESALES). Also added rule with this attributes. In the simulation condition its working fie . 

But when I try creating a CR, the derivation are not being working. I have checked the link

I have also followed the Naming convention (in my case DERIVE_MLANSALES)

Please suggest how to do this.

Thanks
