Create Model Issue

I am facing an issue with data mining create model.

DB version: 12.1.0.2.0 - 64bit

There are 2 users A and B.

User A has data mining privileges. So data mining related package with AUTHID as DEFINER is created in this user.

User B has privilege to access objects of user A.

When I invoke this package from user A (who is owner of this package) create model works fine.

But when i invoke this package from user B, it creates the model with size 0.

Model Name  Mining FunctionAlogirithmCreation DateBuild durationSize
MODEL_123CLASSIFICATIONNAIVE_BAYES05-JAN-1840

Settings

PREP_AUTO => OFF

ODMS_TEXT_POLICY_NAME => ADP_DEFAULT_POLICY

ODMS_TEXT_MAX_FEATURES => 3000

NABS_SINGLETON_THRESHOLD => 0

Please help to fix this.
