[Workflow] How do delete a Workflow in status COMPLETED

While searching for a way to delete a workflow, I came across this blog post: https://community.sap.com/t5/technology-blogs-by-members/how-to-logically-delete-workflows/ba-p/12991725
Unfortunately, logically deleting workflows is only possible when the workflow is not in the status COMPLETED.

Since my workflow was already in this state, I had to find another way, and found it with transaction code SWWL. Simply find the unique Identification of the top level workitem via t-code SWIA and then use it in SWWL. When running the report, you will first get a list, then simply select the result items you want to delete and hit the trash icon, or restart the selection and check the flag for Delete immediately.

[Workflow] Get all Workitems and Workitem Container related to a pernr

If you have connected any workflows to a pernr via BUS1065 (like it is described here), you can receive all related workflows/workitems related to this pernr via the following code:

    NEW cl_def_im_com_bsp_workflow( )->if_ex_com_bsp_workflow~read_workitems_for_object( EXPORTING iv_swo_objtype = 'BUS1065'
                                                                                                   iv_swo_objkey  = CONV #( lv_pernr ) 
                                                                                         IMPORTING et_workitems   = DATA(lt_workitems) ).

    LOOP AT lt_workitems ASSIGNING FIELD-SYMBOL(<workitems>).
      "If you are only interested in specific workflows, you could filter here
      "WHERE wi_rh_task = 'WSxxxxxxxx' 
      "AND   wi_stat    =  'STARTED'.

      NEW /iwwrk/cl_wf_read_workitem( <workitems>-wi_id )->get_wi_container( IMPORTING et_wi_container = DATA(lt_wi_container) ).
      " access container items via lt_wi_container[ element = 'IV_PERNR'  ]-value

    ENDLOOP.

[Workflow] You are not one of the possible agents of task ‘&1’

The Function Module SAP_WAPI_START_WORKFLOW uses RH_TASK_START_CHECK to check, if the calling user is allowed to start the Workflow.
In it RH_TASKS_TO_START is used to read the WF and Task IDs which the user is allowed to call. But it uses a buffer and if you just did some changes to the Workflow Classification, i.e. setting it to General Task,

it can be that this check will continue to fail as it is reading old data from the buffer.

You will receive an error message from Message Class WZ: You are not one of the possible agents of task ‘&1’

I had this problem sometimes when transporting objects to the next system, but until now I could not figure out when it happens and when not.

Luckily the solution is pretty simple, just call T-Code SWU_OBUF and do a buffer refresh/synchronization.
Rob Dielemans has explained the cause very well here.

[ABAP] Read ACTION_COMMENTS from Workitem

The Attribute ACTION_COMMENTS is of type SWC_VALUE, which is a char with length 255.

If the entered text has less than < 255 characters, there is just one element named ‘ACTION_COMMENTS’ in the workitem container.

If the user entered a text with more than 255 characters, the text is split and there are more elements named with ‘ACTION_COMMENTS_1’, ‘ACTION_COMMENTS_2’ etc. (Note 3017539)

There is the function module SAP_WAPI_READ_CONTAINER to read Workitems. As input for the function module, you need the workitemId from the decision step. You will then find the ACTION_COMMENTS in the simple_container table.

    DATA: return_code              TYPE sy-subrc,
          simple_container         TYPE TABLE OF swr_cont,
          message_lines            TYPE TABLE OF swr_messag,
          message_struct           TYPE TABLE OF swr_mstruc,
          subcontainer_bor_objects TYPE TABLE OF swr_cont,
          subcontainer_all_objects TYPE TABLE OF swr_cont,
          object_content           TYPE TABLE OF solisti1.

    " Read the work item container from the work item ID
    CALL FUNCTION 'SAP_WAPI_READ_CONTAINER'
      EXPORTING
        workitem_id              = wiid
      IMPORTING
        return_code              = return_code
      TABLES
        simple_container         = simple_container
        message_lines            = message_lines
        message_struct           = message_struct
        subcontainer_bor_objects = subcontainer_bor_objects
        subcontainer_all_objects = subcontainer_all_objects.


    TRY.
        DATA(text) = simple_container[ element = 'ACTION_COMMENTS' ]-value.
      CATCH cx_sy_itab_line_not_found.
      " Check for ACTION_COMMENTS_1 etc.
      " or follow the approach below
    ENDTRY.

The comment is also added as attachment to the workitem. Just check the table subcontainer_all_objects, which is also returned by the previous function module, for attribute _ATTACH_COMMENT_OBJECTS (or _ATTACH_OBJECT or DECISION_NOTE). With function module SO_DOCUMENT_READ_API1 you can then get the actual comment.

    " Read the _ATTACH_COMMENT_OBJECTS element
    " There can be more than one comment, just take the last one
    LOOP AT subcontainer_all_objects INTO DATA(comment_object) WHERE element = '_ATTACH_COMMENT_OBJECTS'.
    ENDLOOP.

    CHECK comment_object-value IS NOT INITIAL.

    " Read the SOFM Document
    CALL FUNCTION 'SO_DOCUMENT_READ_API1'
      EXPORTING
        document_id    = CONV so_entryid( comment_object-value )
      TABLES
        object_content = object_content
      EXCEPTIONS
        OTHERS         = 1.

    LOOP AT object_content INTO DATA(lv_soli).
      CONCATENATE text lv_soli-line INTO text.
    ENDLOOP.

As you get a table as a result, it’s properly easier to read long comments this way.

[Fiori] Send notification mail if workitem is forwarded in MyInbox

Workitem function modules

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.

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.

BAdI Filter

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.

IF_EX_WF_WI_WORKITEM~CHECK_BEFORE_FORWARD Paramter

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] Add custom message in workflow log

In a function exit of a workflow task, you can copy the sample coding out of class CL_SWH_WORKITEM_EXIT_LOG to append a custom message

METHOD if_swf_ifs_workitem_exit~event_raised .
  DATA: ls_msg TYPE swr_mstruc.
  DATA: ls_por TYPE sibflporb.
  DATA: l_cnt TYPE REF TO if_swf_ifs_parameter_container.

  me->m_ctx = im_workitem_context.
  IF im_event_name EQ swrco_event_after_creation.
    ls_msg-msgid = 'SWH'.
    ls_msg-msgty = 'S'.
    ls_msg-msgno = '100'.
    ls_msg-msgv1 = 'CL_SWH_WORKITM_EXIT_LOG'.
    ls_msg-msgv2 = 'swrco_event_after_creation'.
    l_cnt = m_ctx->get_wi_container( ).
    TRY.
        CALL METHOD l_cnt->get
          EXPORTING
            name  = swrco_wi_leading_object
          IMPORTING
            value = ls_por.
        CALL METHOD m_ctx->set_message_to_log
          EXPORTING
            im_message    = ls_msg
            im_object_por = ls_por.
      CATCH cx_swf_cnt_container .
    ENDTRY.
  ENDIF.
ENDMETHOD.                    "IF_SWF_IFS_WORKITEM_EXIT~EVENT_RAISED

But to add a message in general, only the workitem context is needed. If you got the context, just use method set_message_to_log.

* context type: im_workitem_context TYPE REF TO if_wapi_workitem_context   

" text in im_function will be displayed in workitem log (max char30),
" message in im_message will give further information when clicking on the traffic light (max char 70).
im_workitem_context->set_message_to_log( im_function = |Forward: Mail { var }|
                                         im_message = VALUE #( msgid = '00'
                                                               msgty = 'S'
                                                               msgno = '000'
                                                               msgv1 = |var 1|
                                                               msgv2 = |var 2| ) ).
* In some cases "COMMIT WORK" is needed.

You’ll find the log entry in workitem flog view:

[Fiori] Leave Request Approval Steps with Custom Workflow

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

Default implementation: HCMFAB_LEAVE_APPROVAL_INBOX
Default Workflows and Step ID’s
Add your custom workflow and the custom approval step id in your own BAdI implementation

As second step you have to add the Workflow in the customizing. You’ll find further information here.

SM30 View /IWWRK/V_WFSTEP.
Add the Workflow with Approval StepId
Add the Approve and Reject Buttons

[ABAP] Leave Request Approval Workflow with Escalation

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
      EXPORTING
        im_actor_type = 'P'
        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
        user_id      = lv_userid_approver
        language     = sy-langu
        do_commit    = 'X'
      IMPORTING
        return_code  = lv_subrc.
    IF lv_subrc <> 0.
    ENDIF.
