For example, if your key flexfield segment shares its value set with a descriptive flexfield segment, your security rules also affect that descriptive segment. If you use the same value set for Standard Request Submission parameter values, the rules you assign here also affect your request parameter, provided that the parameter has security enabled.
Many Oracle Applications reports use predefined value sets that you may also use with your flexfield segments. If your flexfield segment uses a value set associated with a Standard Request Submission report parameter, the security rules you define here also affect the report parameter, provided that the parameter has security enabled. In addition, if you query a key flexfield combination where one or more of the segments already contain a secure value, you cannot update any of the segment values in the combination.
Security rules for the Accounting Flexfield also restrict query access to segment values in the Account Inquiry, Funds Available, and Summary Account Inquiry windows. In these windows, you cannot query up any combination that contains a secure value.
