Functional Area in Master Data
You can add the functional area to the master data of various objects:
· G/L account
· Cost element
· Cost center
· Orders
¡ Order type
¡ Internal order
¡ Sales order for make-to-order production and requirements class
¡ Maintenance, service, and QM order
¡ Production order, product cost controller, and cost object hierarchy
· WBS elements
¡ Project profile and project definition
¡ WBS element
· Networks
¡ Network type
¡ Network header
¡ Network activity
During posting, the system derives the functional area from the master data of the assigned objects. For more information, see Deriving the Functional Area.
If you want to be able to enter the functional area in the master data of the specified objects, the Functional Area field in the master data must be ready for input. You need to have activated cost of sales accounting for your company codes or activated it for preparation. You make the settings in Customizing for Financial Accounting (new) under Financial Accounting Global Settings (New) → Ledgers:
· Fields → Standard Fields → Functional Area for Cost of Sales Accounting → Activate Cost of Sales Accounting for Preparation
· Ledger → Activate Cost of Sales Accounting

The master data of the following objects is not company code-dependent, rather it is assigned to higher-level organizational units:
Object |
Assigned organizational unit |
G/L account |
Chart of accounts |
Cost element |
|
Cost center category |
Client |
Order type |
In such cases, the Functional Area field is ready for input in all company codes of a client, provided that the status of cost of sales accounting is either In Preparation or Active for at least one company code of the client.
You have the following options for adding the functional area to the master data of the objects specified:
· Add functional area
You can add the functional area provided that no postings exist for this object.
· Change functional area
You can change a functional area that has already been entered as long as no postings exist. Where postings already exist, you can no longer change the functional area. Postings that have already been made cannot be changed automatically. The functional area is derived only in the case of new postings.

However, if you have to change the functional area and postings already exist, you can change the error message from work area FH with number 600 to a warning message and then change the functional area. You do this in Customizing for Financial Accounting (New) under Financial Accounting Global Settings (New) → Tools → Change Message Control. You then have to transfer existing postings manually.
