Hello,

I have a table material_code I have fields like m_category, name, code.

I have an another table material_example I have same fields m_category, name, code.

I have to set the all the three fields as many2one which is related to the all three fields of the material_example.

But only one field can be set as many2one and it only takes "name" field from material_example.

How can I get all the three fields and relate them with?

Please help me with an example code

Thank you
