[ABAP Env] Create Data Model & OData Service
Recently I worked through the tutorial on creating a travel bookings app in the SAP Cloud Platform ABAP Environment.
Find a good introduction and overview on this topic here: Getting Started with ABAP in the Cloud – Part I
And the travel bookings app tutorial here: Getting Started with ABAP in the Cloud – Part II
These are my notes on the steps needed to create the data model and publish it as oData service.
| # | Layer | Nomenclature | Description |
|---|---|---|---|
| 1 | Database Table | ZTABLE | Place your raw data first |
| 2 | Data Definition (Interface View) | ZI_ | Relation between different tables (e.g. currency or text table) |
| 3 | Projection View (Consumption View) | ZC_ | Configure the UI depending on your scenario. Use different projection views for different usages of the same interface view and the same physical table. |
| 4 | Service Definition | ZSD_ | Expose the projection view (and underlying associations like currency, country…) as service |
| 5 | Service Binding | ZSB_ | How to we want to make the service available? Defines the binding type (OData V2 / OData V4) Activate it with the “Activate” Button within the editor window. Select the Entity and hit “Preview…” to see whtat we defined in our projection view. |
If you’ve done this, you are able to view the data in a generated Fiori Elements app. But if you also want to create, edit, delete data, you’ll have to add some behavior functionality.
| 6 | Behavior Definition on Data Definition | ZI_ | Created on top of the Data Definition. Will get the same name es the Data Definition. Implementation Type: Managed Defines the operations create, delete, edit. |
| 7 | Behavior Implementation on Definition View | ZBP_I_ | The code for the behavior… For the travel app tutorial, some logic for a generated unique key and field validation. The class inherits from cl_abap_behavior_handler. |
| 8 | Behavior Definition on Projection View | ZC_ | Created on top of the Projection View. Will get the same name es the Projection View. Defines the operations create, delete, edit. |

[Fiori] Send notification mail if workitem is forwarded in MyInbox
If you forward a workitem manually from the MyInbox or via function module SAP_WAPI_FORWARD_WORKITEM, the function module SWW_WI_FORWARD will be called. There the SAP implemented a BAdI call of the BAdI WF_WI_FORWARD.
The BAdI provides a method to add additional checks, when forwarding a workitem. I will use it, to send notification mails.
Create your own BAdI implementation and add a task id as filter. In my case it’s the task TS21500003 of the leave request approval workflow.
Now your implementation will only be called, if this specific workitem is forwarded. Now we implement the method CHECK_BEFORE_FORWARD. The method has enough parameters to get all necessary information to enrich the mail text.
First the workitem container is read out of the context. There we get the _WI_OBJECT_ID element, which contains the request object reference. With this information we are able to get the current request object out of the workflow. I pass this into antother class where I already have a mail sending implementation.
METHOD if_ex_wf_wi_workitem~check_before_forward.
*---------------------------------------------------------------------------------*
* This BAdI implementation is used to send an info mail when a workitem is forwarded.
*---------------------------------------------------------------------------------*
TRY.
"Get workitem container and requestId
DATA(container) = im_workitem_context->get_wi_container( ).
container->get_value_ref( EXPORTING name = |_WI_OBJECT_ID|
IMPORTING value_ref = DATA(lr_req_id) ).
ASSIGN lr_req_id->* TO FIELD-SYMBOL(<lpor>).
"Get current request object
DATA(lo_req) = NEW cl_pt_req_wf_attribs( )->bi_persistent~find_by_lpor( lpor = <lpor> ).
"Send an info mail to each new agent (should be only one)
LOOP AT im_table_new_agents INTO DATA(new_agent).
zcl_hcm_leave_request_assist=>send_mail( io_req = CAST cl_pt_req_wf_attribs( lo_req )
iv_tdname = mc_mailtext
iv_pernr = cl_hcmfab_employee_api=>get_instance( )->get_employeenumber_from_user( iv_user = new_agent-objid ) ).
ENDLOOP.
CATCH cx_hcmfab_common.
CATCH cx_swf_cnt_elem_not_found.
CATCH cx_swf_cnt_container.
"In error case, do nothing. The workitem should still be forwarded.
RETURN.
ENDTRY.
"Write Info to WF Log
MESSAGE s001(00) WITH |Forward: Mail { mc_mailtext }| INTO DATA(lv_message).
im_workitem_context->set_message_to_log( im_function = CONV #( lv_message ) "max char30
im_message = VALUE #( msgid = sy-msgid
msgty = sy-msgty
msgno = sy-msgno
msgv1 = sy-msgv1 ) ).
COMMIT WORK.
ENDMETHOD.
At the end I’m writing a little notification in the workflow log. The workitem context provides the method set_message_to_log for this. The log will look like this.
[ABAP] Access leave request attributes
cl_pt_req_badi=>get_request( EXPORTING im_req_id = request_id
IMPORTING ex_request = DATA(request) ).
request->get_all_attribs( IMPORTING ex_attribs_struc = DATA(req_attribs) ).
DATA(req_begda) = req_attribs-version-item_tab[ 10 ]-value.
Take a look in the item_tab to see the specific request values.
