How to pass one contract parameters in to another contract class in AX

Hi,

1. Create the contract as normal you designed with reference to your param list.
2. Add below method.

[
DataMemberAttribute
]
public InventDimViewContract parmNestedContract(InventDimViewContract _nestedContract = InventDimViewContract)
{
    InventDimViewContract = _nestedContract;
    return InventDimViewContract;
}

Here this methods inherits the another contract class called InventDimContract.

3. Dont forgot to declare in class declaration method as

InventDimViewContract              InventDimViewContract ;

Thanks,
