Defining Accounting Flexfield Segment Qualifiers

When you define an account segment value, you can identify it as a qualifying segment value. You must enter the segment qualifier information whenever you define values for any value set that is used by an account that uses segment qualifiers.
You can define the following segment value qualifiers for your Accounting Flexfield:

• Account Type: Defines the account type for the natural account segment value. You can enter only valid account types.

• Budget Entry Allowed: Indicates whether General Ledger should allow detailed budgeting to accounts with this segment value.

• Posting Allowed: Indicates whether General Ledger should allow detailed posting to Accounting Flexfields with this segment value.

• Other Segment Qualifiers: You may have additional segment qualifiers (such as Reconciliation) if your site uses localizations for your country or region.

General Ledger prevent you from changing these qualifiers for segment values that you already defined, unless you first unfreeze your Accounting Flexfield structure. When you change the Budget Entry or Posting Allowed qualifiers for segment values that you have already defined, you should also make a corresponding change to all accounts that include the value in the account definition.

   To set the Account Type segment qualifier:

• Enter a valid account type for this segment qualifier. This segment qualifier requires a value for the natural account segment only. Accounts have the same account type as the natural account segment value they include.

The default value for this field is Expense. Accept this value or change it to one of the other valid account types. Enter the type of your proprietary account (Asset, Liability, Owners' Equity, Revenue or Expense) or the type of your budgetary account (Budgetary Dr or Budgetary Cr) your segment value represents. Choose any proprietary balance sheet account type if you are defining a statistical account segment value. If you choose a proprietary income statement account type for a statistical account segment value, your statistical balance will zero-out at the end of the fiscal year.

You can change the Account Type segment qualifier by unfreezing all Accounting Flexfield structures that reference the natural account segment. Changing the account type only affects new accounts created with the reclassified natural account segment; it does not change the account type of existing accounts.

   To set the Budget Entry Allowed segment qualifier:

• Enter Yes for Budget Entry Allowed to perform detailed budgeting for accounts with this segment value. If you do not allow budget entry for a segment value, you cannot assign accounts with this segment value to budget organizations, and you cannot define budget formulas for those accounts.

If you are defining a parent segment value, you must enter No. You cannot budget amounts to a segment value that references other segment values where detail budgeting is already allowed.

   To set the Posting Allowed segment qualifier:

• Enter Yes for Posting Allowed to allow detailed posting to accounts with this segment value. If you do not allow posting for a segment value, you cannot use accounts with this segment value when you enter journals, and you cannot use the accounts in recurring journals.

If you are defining a parent segment value, you must enter No. You cannot post amounts to a segment value which references other segment values where detail posting is already allowed.
