Review existing key flexfields when you update your cross-validation rules to maintain consistent validation. Regardless of your current validation rules, Oracle E-Business Suite accepts a key flexfield combination if the combination already exists and is enabled. Therefore, to ensure accurate validation, you must review your existing combinations and disable any combinations that do not match the criteria of your new rules.
Suggestion: To keep this type of key flexfield maintenance to a minimum, decide upon your cross-validation rules when you first set up your key flexfield structure.
If you want to prevent users from using previously-existing combinations that are no longer valid according to your cross-validation rules, you can always disable those combinations using the combinations form.
Refer to the Oracle General Ledger documentation for information on defining accounts in the Accounting Flexfield.
