accounts.put("Total_Debits", total_Fp_Dr); 
accounts.put("Total_Credits", total_Fp_Cr); 
BasicDBObject update = new BasicDBObject(); 
update1put("$push", new BasicDBObject("Accounts.$.Total_Debits",total_Fp_Dr));

Попробуйте реструктуризации ваши вопросы следующим образом:

DBObject searchQuery = new BasicDBObject("_id", id).append("Date", date); 
DBObject accountsArray = new BasicDBObject("Accounts", 
          new BasicDBObject("Date", date) 
           .append("Total_Debits", total_Fp_Dr) 
           .append("Total_Credits", total_Fp_Cr)); 

DBObject updateQuery = new BasicDBObject("$push", accountsArray); 
accountHeads.update(searchQuery, updateQuery);
