Duplicates in SAP Query (crmd_order_index)

Hello, SAP-friends!

I'm trying to get all Bus.Transaction of a particular partner using table CRMD_ORDER_INDEX in sap query.

I insert the part number and in the result screen I get more items than it has to be (here are some duplicates items). My result differences compared with B.Tr CRMD_ORDER using search criteria as business partner number or b.tr se16-CRMD_ORDER_INDEX, here I get another result without duplicates! What is problem in SAP Query?

Did anyone face this problem?

Thanks in advance!
