Input Key

Hi there,

Please help me understand this issue below and please provide me a solution

[Target Table:TAR_PRICE(Target_Datastore.TAR)]

Column <TAR_PRICE_ID> is a key column for target <TAR_PRICE(Target_Audit_Datastore.AUD)> but does not match any column from the input schema.  Also, the 'Use Input Key' check box on target's Option property page is not selected. If the output schema has unmatched key columns, then the 'Use Input Key' check box must be selected. (BODI-1111042)
