Supply function class :- CL_WDABAP_FLIGHT_MODEL

[Former Member]

Hi Everyone,

This is regarding the sample codes posted below. Can any one please let me know where is CL_WDABAP_FLIGHT_MODEL class coming from. This is not a global class I have checked in SE24. Another question I am using table vbak instead of sflight. SO in my case also do we have a class like the one above.... if yes where do I find that ...........

method GET_BOOKINGS . data: Itab_Bookings type IF_COMPONENTCONTROLLER=>Elements_Bookings, Stru_Bookings like line of Itab_Bookings, Stru_FlightList type if_componentcontroller=>Element_FLIGHT_LIST. parent_element->get_static_attributes( importing static_attributes = Stru_FlightList ). Itab_bookings = CL_WDABAP_FLIGHT_MODEL=>GET_BOOKINGS( CARRID = Stru_FlightList-airlineid CONNID = Stru_FlightList-connectid FLDATE = Stru_FlightList-flightdate ). node->bind_table( Itab_bookings ). endmethod.

Implement supply method GET_BOOKINGS which fills the node BOOKINGS with booking information, according to the selected flight. Use the static GET_BOOKINGS method of the class CL_WDABAP_FLIGHT_MODEL.

Thanks,

Anu.

Hi

CL_WDABAP_FLIGHT_MODEL is not present in some systems.

I hope you are learning this from SAP Standard course, which is available only in the training servers.

It is just a business logic to get the flight details, you can create your own function module and call it here.

It should be not possible to use an productive System for the sap tutorials.

But if I want to do it anyway with a temporary package and then it is not forbitten - or?

Why is ther no note for each different sap-system to get the object thorugh a note and I must not create it by myself?

Is there anywhere a tutorial to crate the clas CL_WDABAP_FLIGHT_MODEL?

For me next important ist the method CL_WD_FLIGHT_MODEL=>GET_BOOKINGS.

Thank you for help

This class was only created to support TechEd workshops. Therefore there is no note for it. It was shipped in the developer edition/sneak preivew NSP ABAP system you can download from SDN, but I don't believe it is in the standard SAP_BASIS software component. All this class really does is hide the SQL statements to read from the SFLIGHT tables. For example here is the code for GET_BOOKINGS:

select * from sbook into table bookings where carrid = carrid and connid
 = connid and fldate = fldate.

CL_WDABAP_FLIGHT_MODEL was written by a colleague in Product Management (not by development) to only support the TechEd Web Dynpro ABAP session. It is present in the the SDN Sneak Preview systems because we shipped a lot of the TechEd exercises via that system image.

In general you will NOT find special model classes for the standard business objects. What you will find is BAPIs and/or Enterprise Services that make an excellent foundation for safely interacting with standard business objects.
