Inserting a row in FA_TAX_INTERFACE I've got Error Unique constraint violated

I need to update the cost of an asset that have been previously updated  through the interface table . When I try to insert the new row for the cost update needed in this period  in FA_TAX_INTERFACE table,  I've got Error Unique constraint violated.

In Note:

FATAXUP Error: ORA-00001: Unique Constraint (FA.FA_TAX_INTERFACE_U1) Violated  (Doc ID 2386088.1), it is indicated to purge the table.

Could anyone tell me if this is valid for any case?

Can I delete from FA_TAX_INTERFACE the previous records without any consequences?

Thanks!!
