Product master classification CIF issue

Hello,

I am trying to CIF material master with class-001, but Product master is created in APO without class assignment.

Class has been assigned with Organization area - A in both ECC & APO and same is assigned in characteristics tab also. I ensured that class is available in APO before transferring the material master.

I am getting message that 'No allocation found' in Product master classification tab.

Regards,

Dharma
