split data based on three columns to multiple sheets and rename sheets based on headers

hi
I have data in sheet MAIN the result should be after it so it should split data based on COL B,C,D and the sheets names should be based on headers when create the new sheets after split them . every time increase data in sheet MAIN then should updating in the created sheets . so the result in sheets IMPORT,EXPORT ,RETURNS
sorry if it's poor detailes , but I think the result after sheet main will be clear . if it's not clear please inform me
