Create Behavior Definition for BO-Part 2

To save data properly using Behavior definition Data mapping is important. As of now field names are different in our BO entity and the table /dmo/travel_m where we want to store the data.

Travel Entity:

Code snippet showing data field mappings for travel-related identifiers including travel_id, agency_id, and customer details.

Travel Table:

Code snippet defining a database table for travel management, including fields like travel_id, customer_id, booking_fee, total_price, and status.

For example Root entity field is TravelId and table field is travel_id.

Let’s start with mapping.

Open the BDEF ZHA_SA_TRAVEL and add mapping fields for /dmo/travel_m,

			
managed implementation in class zbp_ha_sa_travel unique;
strict ( 2 );
define behavior for ZHA_SA_TRAVEL alias Travel
persistent table /dmo/travel_m
lock master
authorization master ( instance )
etag master LastChangedAt
{
  create ( authorization : global );
  update;
  delete;
//  field ( readonly ) TravelId;
  association _Booking { create; }
mapping for /dmo/travel_m{
TravelId = travel_id;
AgencyId = agency_id;
CustomerId = customer_id;
BeginDate = begin_date;
EndDate = end_date;
TotalPrice = total_price;
CurrencyCode = currency_code;
BookingFee = booking_fee;
LastChangedAt = last_changed_at;
LastChangedBy = last_changed_by;
CreatedAt = created_at;
CreatedBy = created_by;
OverallStatus = overall_status;
Description = description;
}
}
define behavior for ZHA_SA_BOOKING alias Booking
persistent table /dmo/booking_m
lock dependent by _Travel
authorization dependent by _Travel
etag master LastChangedAt
{
  update;
  delete;
  field ( readonly ) TravelId;
  association _Travel;
  association _BookingSupplement { create; }
mapping for /dmo/booking_m{
TravelId  = travel_id;
BookingId = booking_id;
BookingDate = booking_date;
CustomerId = customer_id;
CarrierID = carier_id;
ConnectionId = connection_id;
FlightDate = flight_date;
CurrencyCode = currency_code;
BookingStatus = booking_status;
LastChangedAt = last_changed_at;
}
}
define behavior for ZHA_SA_BOOKSUPPL alias BookingSuppl
persistent table /dmo/booksuppl_m

etag master LastChangedAt

  field ( readonly ) TravelId, BookingId;
  association _Travel;
  association _Booking;
mapping for /dmo/booksuppl_m{
TravelId = travel_id;
BookingId = booking_id;
BookingSupplementId = booking_supplement_id;
SupplementId = supplement_id;
price = price;
CurrencyCode = currency_code;
LastChangedAt = last_changed_at;
}
}
