The Oracle Applications store these "codes" in key flexfields. Key flexfields are flexible enough to let any organization use the code scheme they want, without programming.
When your organization initially installs Oracle Applications, you and your organization's implementation team customize the key flexfields to incorporate code segments that are meaningful to your business. You decide what each segment means, what values each segment can have, and what the segment values mean. Your organization can define rules to specify which segment values can be combined to make a valid complete code (also called a combination). You can also define relationships among the segments. The result is that you and your organization can use the codes you want rather than changing your codes to meet Oracle Applications' requirements.
For example, consider the codes your organization uses to identify general ledger accounts. Oracle Applications represent these codes using a particular key flexfield called the Accounting Flexfield. One organization might choose to customize the Accounting Flexfield to include five segments: company, division, department, account, and project. Another organization, however, might structure their general ledger account segments differently, perhaps using twelve segments instead of five. The Accounting Flexfield lets your Oracle General Ledger application accommodate the needs of different organizations by allowing them to customize that key flexfield to their particular business usage. See: the Oracle General Ledger User's Guide.
Attention: Throughout this guide we use the "Part Number Key Flexfield" in our examples and graphics. We use this example because it helps to illustrate the uses and behaviors of key flexfields without requiring any specialized accounting, human resources, or manufacturing knowledge. However, there is no actual "Part Number Key Flexfield" in the Oracle Applications, and you should not confuse it with the System Items Flexfield (Item Flexfield) used by many Oracle Applications products such as Oracle Inventory.
