data service full load failure due to duplicate key in object

Hi there,

I have a job to do a full and delta load of general ledger data from ERP to SQL via SAP data service. The delta load is working without problem. But the full load met an issue when I triggered. The error message is as "

<[Microsoft][SQL Server Native Client 10.0][SQL

  Server]Violation of PRIMARY KEY constraint 'PK__SAP_GL_L__9F83A9C50323BE7C'. Cannot insert duplicate key in object dbo.xxx" . The duplicate key value is '200,200001......'. Any hint on this issue? Thanks for any help!
