Sql to Sql table load

Hi,

I tried loading a sql server table form 1 db to another.

i got an err saying

11524 8612 DBS-070401 4/4/2014 2:54:21 AM Server]The INSERT permission was denied on the object 'XXXX, database 'XXX', schema 'dbo'.

I used windows authentication for both source and destination data stores.

but when i try it in sql server am able to load data, so i have enough access on that table.
