Crystal reports repeating the items when i am using the query with dataset

[kumar2kx]

I am new to crystal report. At the time of binding the datas from dataset the crystal report showing twice or thrice.

i checked in dataset also at the time of debugging but in dataset only i am having 5 records but in my crystal its showing 10 records.

Below is my Code:

 ReportDocument doc = new ReportDocument();
 
 sda = new SqlDataAdapter(" SELECT ac_mstr.AC_DESC, TRAN_HDR.DOC_DT, TRAN_DTLS.GL_CODE, DBCR, AMT FROM dbo.TRAN_DTLS TRAN_DTLS INNER JOIN dbo.AC_MSTR ac_mstr ON (TRAN_DTLS.SUB_CODE=ac_mstr.SUB_CODE) AND (TRAN_DTLS.GL_CODE=ac_mstr.GL_CODE) INNER JOIN dbo.TRAN_HDR TRAN_HDR ON (TRAN_DTLS.TC=TRAN_HDR.TC) AND (TRAN_DTLS.DOC_NO=TRAN_HDR.DOC_NO) where tran_hdr.tc='CAS' and tran_hdr.doc_dt between '2012/01/01' and '2012/12/30'   ORDER BY TRAN_DTLS.GL_CODE", con);
 
            sda.Fill(ds);                    doc.Load(Server.MapPath("~/Reports/Acc_sum.rpt"));
 
   doc.SetDataSource(ds.Tables[0]);
   CrystalReportViewer1.ReportSource = doc;

Can any one help Me?
