Thanks for your reply, There is difference in activity type pricing – it is not taking from routing

where I have to make the configuration setting to correct the cost

one thing to note here in production order – if I released the production order with the same cost and make the goods issue against this production order, activity confirmation, and finished goods receipt In stock against this production order – then at last while I am checking the variance against the production order- there was no variance – I understand that there was no variance recorded compare to plan and actual but since there was variance on production order costing analysis.
