Import creating extra entry in Location Data Tuple

Hi Experts,

I am using SAP MDM SP 04 in which I have a xml which has Plant level data and is imported in to Location Data Tuple.

On import I am using set Ruple update with all field as matching fields.

For New records - Create

For Existing records - Update Mapped

In few records I am getting an error with Two entries in Tuple,one valid and another with just one field filled in and others not populated.

Please help me resolve this, and also explain why is it happening?

Please Guide!

Thanks in advance,

Ravi
