If you want to copy the standard workflow of the leave request approval process (WS12300111) and are adding another approval step (or you just want to add an escalation where you set the approve workitem to obsolete and create a new approval step for the next approver) you have to implement the following BAdI. In detail you only have to add the new step ID in the filter, else the approver will not see any approval or reject buttons in his inbox. See details here.
BAdI: /IWWRK/BADI_WF_BEFORE_UPD_IB
As second step you have to add the Workflow in the customizing. You’ll find further information here.
During the leave request approval process the standard workflow WS12300111 does not include any deadlines. To archieve this you can simply copy the workflow and add a deadline at the approval task (Step 38). There are two possible ways to forward the approval step to the next processor: 1. When deadline is reached, forward the current workitem to the next approver. 2. When deadlines is reached, set current workitem to obsolete and create a new workitem and assign it to the next approver. Then you also have to add the new step ID to this BAdI Filter.
I selected the first option. In my demo the escalation is triggered after just three minutes.
The deadline generates a new exit on the approval step.
In this new exit you are able to call your own logic on finding the new approver, forward the workitem and inform him via mail if necessary.
To forward the request to the next approver, you have to forward the workitem and also set this new approver as next processor in the current leave request. So first identify the next approver. I used RH_GET_LEADER for this.
*--------------------------------------------------*
* Get next approver
*--------------------------------------------------*
CALL FUNCTION 'RH_GET_LEADER'
EXPORTING
plvar = '01'
keydate = sy-datum
otype = is_approver-otype
objid = CONV realo( is_approver-objid )
IMPORTING
leader_type = lv_leader_type
leader_id = lv_leader_id
EXCEPTIONS
no_leader_found = 1
no_leading_position_found = 2
OTHERS = 3.
CHECK lv_leader_type EQ 'P' AND lv_leader_id IS NOT INITIAL.
CALL FUNCTION 'HR_GET_USER_FROM_EMPLOYEE'
EXPORTING
pernr = CONV pernr_d( lv_leader_id )
iv_with_authority = abap_false
IMPORTING
user = lv_userid_approver.
ev_approver-otype = |US|.
ev_approver-objid = lv_userid_approver.
Then set this new approver as next processor in your request. While doing this, it’s recommended to enqueue and dequeue the request. To get the current request object use class cl_pt_req_badi.
*--------------------------------------------------*
* Set new approver in request
*--------------------------------------------------*
" Enqueue the request
CALL FUNCTION 'ENQUEUE_EPTREQ'
EXPORTING
mode_ptreq_header = 'S'
mandt = sy-mandt
request_id = io_req->req_id
EXCEPTIONS
foreign_lock = 1
system_failure = 2
OTHERS = 3.
" Get the request object instance
CALL METHOD cl_pt_req_badi=>get_request
EXPORTING
im_req_id = io_req->req_id
IMPORTING
ex_request = DATA(lcl_request).
CALL METHOD lcl_request->set_next_processor

im_plvar = '01'
im_otype = 'P'
im_objid = CONV #( lv_leader_id ). " PERNR of Next Approver
IF sy-subrc = 0.
COMMIT WORK AND WAIT.
ENDIF.
" Dequeue the request
CALL FUNCTION 'DEQUEUE_EPTREQ'
EXPORTING
mode_ptreq_header = 'S'
request_id = io_req->req_id.
Finally forward the workitem to the new approver. There of course you need the right workitem ID of the approving step.
*--------------------------------------------------*
* Forward workitem to next approver
*--------------------------------------------------*
CALL FUNCTION 'SAP_WAPI_FORWARD_WORKITEM'
EXPORTING
workitem_id = iv_wi_id "woritem id of approving step

IF lv_subrc <> 0.
ENDIF.
Recently I got the demand to enhance the leave request approvel workflow with some mail steps. These mails should also include the attachments, which can be uploaded in the “Leave Request” Fiori App.
To achive this, I used the exit functionality in the mail step.
There you have to provide a class name. The class has to implement the following interface:
IF_SWF_IFS_WORKITEM_EXIT
You will get a method you can implement.
This Method has two parameters, the “Event Name” and the “Workitem Context”.
With the event, you are able to control, in which situations your exit should be fired. In my case, I just need my code run when the workitem is created (event “CREATED”). You’ll find all usable events in domain SWW_EVTTYP.
To get and pass back the attachment to the mail step, a few things need to be done. First, get the curent workitem container and check, if there is already any attachment. If not, read the request id from the leave request. With this request id, you are able to find the attachment you need. I’ve already written a method for that, you’ll find below. Then convert the xstring to a solix table, create the attachment document with function module “SO_DOCUMENT_INSERT_API1” and “SWO_CREATE” and finally pass it to the container.
