6091   Index(es) open on destination table

   Problem:   A Copy To or Append From operation was attempted on the
   server, but index(es) are open on the destination table, so the operation
   was performed on the client.

   Solution:  Close all open indexes on the destination table before
   attempting the Copy To or Append From operation on the server.  Then
   re-open the indexes when the operation is completed and re-build the
   indexes.
