Flexfield Qualifier

A flexfield qualifier identifies a particular segment of a key flexfield. Usually an application needs some method of identifying a particular segment for some application purpose such as security or computations. However, since a key flexfield can be customized so that segments appear in any order with any prompts, the application needs a mechanism other than the segment name or segment order to use for segment identification. Flexfield qualifiers serve this purpose. You can think of a flexfield qualifier as an "identification tag" for a segment.

For example, 

Your Oracle General Ledger product needs to be able to identify which segment in the Accounting Flexfield contains balancing information and which segment contains natural account information. Since you can customize the Accounting Flexfield so that segments appear in any order with any prompts, 

Oracle General Ledger needs the flexfield qualifier to determine which segment you are using for natural account information. When you define your Accounting Flexfield, you must specify which flexfield qualifiers apply to which segments

Other applications, such as Oracle Human Resources, also use flexfield qualifiers. Oracle Human Resources uses flexfield qualifiers to control who has access to confidential information in flexfield segments.
