An optional string containing an alternate identifier for the current user. For example, this could be a membership number or e-mail address. This is used only for Restricted promotions.

The information in each entry is trusted by the ReservePromoCodes component for the amount of time specified by the i_PromoCodeRenewReservationAfter_Minutes resource property setting. After that interval has elapsed, a new lookup on the promotion code is performed and the entry is rebuilt with fresh information. |

A Simplelist of Dictionaries that correspond to PromoCodeRecordCollection. On output, there is exactly one entry in this list for each promotion code string in the promo_codes list. The information in each entry is trusted by the ReservePromoCodes component for the amount of time specified by the i_PromoCodeRenewReservationAfter_Minutes resource property setting. After that interval has elapsed, a new lookup on the promotion code is performed and the entry is rebuilt with fresh information. |

Remarks
The ReservePromoCodes pipeline component typically runs in the Basket pipeline just before the OrderDiscount (PCR) pipeline component in the Order Adjust Price stage. The ReservePromoCodes pipeline component validates and reserves promotion codes. All promotion codes must be validated, but reservations are only required for limited promotion codes where the number of codes that have not yet been redeemed already has dropped below a configured threshold. Validation depends on the type of promotion code.
A public, unlimited promotion code can usually be validated by a fast lookup in the Discount cache, which is a ContentList Object. Public promotion codes available for a given promotion code definition that has a limit, and private or restricted promotion codes require validation against the database. The validation for public, limited promotion codes verifies that there are promotion codes available. If the number of limited promotion codes drops below the threshold configured in the ReservationRequiredThreshold property of the marketing resource, a reservation is required. If a reservation is granted, the promo_code_info property Reserved is set to True.
For restricted promotion codes, the profile's user_id or the Basket's promo_user_identity must match a value in the u_pc_target_user column of the mktg_promocode table for the promotion code.
For private promotion codes, the promotion code must be valid, and, if a user was specified when the promotion code was defined, the profile's user_id or the Basket's promo_user_identity must match the u_pc_target_user column of the mktg_promocode table for the promotion code.
