As far as I know, No. But why don't you keep another column 'source_final' and you populate it with value from sourc1 or sourc2 depending on what has value(Look at transformer, may be script transformer) . then in schema.xml
<copyField source="source_final" dest="dest"/> Thanks James http://www.click2money.com From: Blargy [via Lucene] [mailto:ml-node+722785-1511121936-124...@n3.nabble.com] Sent: Thursday, April 15, 2010 5:54 PM To: caman Subject: CopyField Is there anyway to instruct copy field overwrite an existing field, or only accept the first one? <copyField source="source1" dest="dest"/> <copyField source="source2" dest="dest"/> Basically I'm want to copy source1 to dest (if it exists). If source1 doesnt exist then copy source2 into dest.
