thanks Ronald for your fast response, but what im looking for is to treat with DB procedure with input parameters as object with its associations and get an output from procedure when execute it as object and its association, consider that i have header entity with two child entities as 1-M relation with header table, i need to pass all these entities to database procedure for some calculations and return another header table with 1-M child table...
