A company code is assigned organizational units like plants, purchasing organizations, and sales organizations. A controlling area can be assigned to one or many company codes and oversees activities like cost center accounting. A company code can only have one chart of accounts. There are two types of fiscal year variants: calendar year and year dependent. Year dependent variants have changing month end dates each year. Postings do not occur in special periods in materials management. A company code can have three currencies configured: the local currency and two parallel currencies. Additional ledgers are only needed for the third parallel currency if it is different than the second.
