Processing more in detail

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. To see more about using those functions check https://transport-freight-management.docs.developers.aeb.com/docs/getting-started-with-carrier-connect.

But don't worry, there are a still few complementary features that we provide out of the box. So you don't have to develop everything from scratch.

Task	Class
Determination of the org unit	Freight 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	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 reference	Freight 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.

PARAMETERS: vbeln TYPE likp-vbeln.

DATA:
  likp             TYPE likp,
  lipss            TYPE STANDARD TABLE OF lips,
  vbpas            TYPE STANDARD TABLE OF vbpa,
  vekps            TYPE STANDARD TABLE OF vekp,
  org_unit_rule_bc TYPE REF TO /aeb/cl_pa_pb_dlv_ou_rule_bc,
  org_unit         TYPE string.

SELECT SINGLE * FROM likp INTO likp WHERE vbeln = vbeln.
SELECT * FROM lips INTO TABLE lipss WHERE vbeln = vbeln.
SELECT * FROM vbpa INTO TABLE vbpas WHERE vbeln = vbeln.
SELECT * FROM vekp INTO TABLE vekps WHERE vpobjkey = vbeln.


org_unit_rule_bc = /aeb/cl_pa_pb_dlv_ou_rule_bc=>new_for(
        im_likp = likp 
    im_lipss = lipss ).
    
org_unit = org_unit_rule_bc->get_org_unit( ).

WRITE: 'OrgUnit: ' , org_unit.
WRITE /.

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.

DATA:
  likp             TYPE likp,
  lipss            TYPE STANDARD TABLE OF lips,
  vbpas            TYPE STANDARD TABLE OF vbpa,
  vekps            TYPE STANDARD TABLE OF vekp,
  org_unit_rule_bc TYPE REF TO /aeb/cl_pa_pb_dlv_ou_rule_bc,

  engn_prm_mo      TYPE REF TO /aeb/if_pa_pb_engn_prm_mo.

SELECT SINGLE * FROM likp INTO likp WHERE vbeln = vbeln.
SELECT * FROM lips INTO TABLE lipss WHERE vbeln = vbeln.
SELECT * FROM vbpa INTO TABLE vbpas WHERE vbeln = vbeln.
SELECT * FROM vekp INTO TABLE vekps WHERE vpobjkey = vbeln.


org_unit_rule_bc = /aeb/cl_pa_pb_dlv_ou_rule_bc=>new_for( im_likp = likp im_lipss = lipss ).
org_unit = org_unit_rule_bc->get_org_unit( ).

WRITE: 'OrgUnit: ' , org_unit.
WRITE /.

engn_prm_bc = /aeb/cl_pa_pb_engn_prm_bc=>get_instance( ).
engn_prm_mo = engn_prm_bc->get_engn_prm_do_for( org_unit ).

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.

DATA:
  likp             TYPE likp,
  lipss            TYPE STANDARD TABLE OF lips,
  vbpas            TYPE STANDARD TABLE OF vbpa,

  engn_prm_mo      TYPE REF TO /aeb/if_pa_pb_engn_prm_mo,
  collector_bc     TYPE REF TO /aeb/cl_pa_pb_dlv_shp_coll_bc,
  shipment         TYPE /aeb/pa_pb_dl_shp_req_do.

SELECT SINGLE * FROM likp INTO likp WHERE vbeln = vbeln.
SELECT * FROM lips INTO TABLE lipss WHERE vbeln = vbeln.
SELECT * FROM vbpa INTO TABLE vbpas WHERE vbeln = vbeln.
SELECT * FROM vekp INTO TABLE vekps WHERE vpobjkey = vbeln.


org_unit_rule_bc = /aeb/cl_pa_pb_dlv_ou_rule_bc=>new_for( im_likp = likp im_lipss = lipss ).
org_unit = org_unit_rule_bc->get_org_unit( ).

WRITE: 'OrgUnit: ' , org_unit.
WRITE /.

engn_prm_bc = /aeb/cl_pa_pb_engn_prm_bc=>get_instance( ).
engn_prm_mo = engn_prm_bc->get_engn_prm_do_for( org_unit ).

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

collector_bc = /aeb/cl_pa_pb_dlv_shp_coll_bc=>new_for( im_likp = likp
                                                       im_lipss = lipss
                                                       im_vbpas = vbpas
                                                       im_vekps = vekps ).

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.

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( ) ...
