Hi,

  I am trying to extract the SQL query from AOT Object(smmSalesCustItemStatistics) in MS Dynamic AX 2012 R3.

Please help me by providing step by step guidance to extract it. I am new starter for Dynamics and have started a week ago,so I don't have much knowledge about this stuff. Please provide me the code which will help me to extract the SQL Query .

Thanks
