I'm using the WebCenter content version 12.2.1.3.0 and using the document transfer utility to upload legacy document in content server.

but facing some problems like below

1) unable to set custom metadata fields value in content server. Please suggest how we can do?

2) dDocAccount value is mandatory to pass. how we can avoid it?.3) dDocAccount value adding 0001/0010/0100 then during checkin it's adding the value to document as 0001$/0010$/0100. Please suggest how we can avoid this $ symbol. ThanksSanjeev
