Incorect dataload in SAP BI 7.0

We are using BI 7.0 version currently. We have issues while loading data into the data targets with the help of DTP process.

Problem: We created transformations to load the Cube. We got the data from r/3 into the PSA first. The no of records that came in were 5500. Now when we load these records into the Cube the no of records get doubled ie 1100. ie) For 1 particular record, 2 different records are created. The Characterstics remain the same but the Key figure value comes to be 0 for the duplicate record that is created. So logically it wont impact the data, but the number of records doubles up.

Best regards,
