get commerce order variables dpm without loading order again I try to get order variables using devel module from inside custom order template page--admin--commerce--orders__%.tpl.php.

I use code $order = commerce_order_load(123); 

Question: is it possible not to load full order again and get the variables ? (assuming that I am on order page, the variables should be loaded anyways correct?)
Thank you for explanation.
You need to use commerce_order_load to load the order with all the data. If the order already has been loaded somewhere else on the page, the order won't be loaded twice, but the order will be fetched from static cache instead. So it's fine to load the same order multiple times.

If you do need to clear the cache, (maybe you need to compare the order to what is in the datebase to see what has changed), then you can use use commerce_order_load_multiple or call entity_load directly.
