Advanced shipment processing

Sometimes it is necessary to use the full functionality of Carrier Connect. For this requirement you can use the class /AEB/CL_PA_PB_CARRIER_BF. This class allows to directly address the Carrier Connect functions completely. For a detailed view check https://transport-freight-management.docs.developers.aeb.com/docs/getting-started-with-carrier-connect.

To support you building up the required data structures, there are some complementary features :

TaskClass
Determination of the org unitFreight order: /AE1/CL_PA_PB_FRO_OU_RULE_BC
Delivery: /AEB/CL_PA_PB_DLV_OU_RULE_BC
Shipment: /AEB/CL_PA_PB_SHP_OU_RULE_BC
Determination of connection parms/AEB/CL_PA_PB_ENGN_PRM_BC
Collecting data for a shipment
This function provides the basic data based on the settings in the configuration. It runs also through the "AFTER_STD_FILLING"-method of the according BAdI for each object.
Freight order: /AE1/CL_PA_PB_FRO_SHP_COLL_BC
Delivery: /AEB/CL_PA_PB_DLV_SHP_COLL_BC
Shipment: /AEB/CL_PA_PB_SHP_SHP_COLL_BC
Determination of the shipment referenceFreight order: /AE1/CL_PA_PB_FRO_SHP_REF_BC
Delivery: /AEB/CL_PA_PB_DLV_SHP_REF_BC
Shipment: /AEB/CL_PA_PB_SHP_SHP_REF_BC
Determination of the workstation ID/AEB/CL_PA_PB_WSTA_ID_BC

In the following program you will see a reference implementation that combines those functions. The task is to implement the same as seen in the "the first shipment"- part, but now using the functions above. First thing is to determine an organisational unit.

REPORT zaeb_create_first_shipment.

WRITE: 'OrgUnit: ' , org_unit.

If you run the report the org unit should be shown. The next step is to determine the connection parameter with this org unit.

REPORT zaeb_create_first_shipment.

PARAMETERS: vbeln TYPE likp-vbeln.

WRITE: 'Destination: ' , engn_prm_mo->get_destination( ).
WRITE: 'Engine client: ' , engn_prm_mo->get_engine_client( ).

If you run the report again the destination and engine client will be printed on screen. Now we need the data for the shipment.

REPORT zaeb_create_first_shipment.

PARAMETERS: vbeln TYPE likp-vbeln.

  likp             TYPE likp,

shipment = collector_bc->create_shipment( org_unit ).

write shipment-referencenumber1.
WRITE /.

Now the program has collected data of the delivery, e.g. the reference number. What you need as well for printing the label is a workstation ID. Just add the following code lines to the program.

DATA: workstation_id TYPE string.
workstation_id = /aeb/cl_pa_pb_wsta_id_bc=>new( )->get_workstation_id( ).
write: workstation_id.
write /.

Now you have everything to create your first shipment. You have to combine the data you collected with the class /AEB/CL_PA_PB_CARRIER_BF. Add the following code to your report.

With the above report you will either see the error messages on screen or no output when the shipment was processed successfully.

Now that you know which functions you need to combine using /AEB/CL_PA_PB_CARRIER_BF you should be able to implement everything else what is possible via this API. In addition, there is a function module /AEB/PA_PB_GET_CAR_PROPS that enables you to get the master data information from Carrier Connect.

Note: The public class will not write log entries. You can use the class /AEB/CL_PA_PB_LOGGER_BC and use the response data from the call to write a log entry. You can use the result type to determine if you should write an error or a warning log entry e.g. IF result->has_error( ) = 'X'. logger->create_log_error( ). ELSEIF result->has_warning( ) ...
