Missing Unit Cost field in Misc Transaction for a Maintenance Organization

Content

I have define two organizations, one for Manufacturing and another for Maintenance. I am trying to create a misc transaction for an item in both the organizations. I would like to add cost while creating this transaction. However, while I can see the field Unit Cost for Manufacturing Organization, I cannot see the Unit Cost field when I try to perform this transaction for a Maintenance Organization.

Any ideas if I am missing any setups. We have completed all the required setups for costing. 

Thanks in advance for your help
