Binding Structure/Internal Table to Workflow from Webdynpro

Question

Hi Gurus,
I have to trigger workflow from WEBDYNPRO application. For now I have two ways they are:
1. Triggering WFLow using SAP_WAPI_START_WORKFLOW (Successfull):
How could I bind Structure/Internal Table (DDIC referred structure) to workflow directly. Presently I am mapping indvidual fields which makes my code complex using FM SAP_WAPI_START_WORKFLOW.
2. Triggering WFLow using SAP_WAPI_CREATE_EVENT (Bindind issues):
Also When I try to submit using BOR event with SAP_WAPI_CREATE_EVENT workflow triggers successfully But I cannot able to bind the values. So are there any specific configuration need to be made.( like making task as General while triggering workflow using SAP_WAPI_START_WORKFLOW).

Answer 1

Hi
Please make use of the below code
INCLUDE cntn01_swc.
DATA lt_kna1    TYPE TABLE OF kna1.
DATA lt_cont    TYPE TABLE OF swcont.
DATA lv_wiid    TYPE          sww_wiid.
swc0_create_container  lt_cont.
SELECT * FROM kna1 INTO TABLE  lt_kna1 UP TO 10 ROWS.
swc0_set_table lt_cont 'CUST' lt_kna1.
CALL FUNCTION 'SWW_WI_START'
  EXPORTING
    creator                      = sy-uname
    task                         = 'WSXXXXXXXX'
    do_commit                    = 'X'
  IMPORTING
    wi_id                        = lv_wiid
  TABLES
    wi_container                 = lt_cont
  EXCEPTIONS
    id_not_created               = 1
    read_failed                  = 2
    immediate_start_not_possible = 3
    execution_failed             = 4
    invalid_status               = 5
    OTHERS                       = 6.
IF sy-subrc <> 0.
  MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
          WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
ENDIF.
The other way to do is you  can also make use of OO ABAP classes to trigger the workflow. If you want to create a rfc function module then create a wrapper function module .
SAP_WAPI_START_WORKFLOW cannot transfer structures or tables which are more thatn 255 characters. So the work around is  either make use of  OO  container or SWCONT container.
The above code snippet should be included in the assistance class of the webdynpro application and you need to include the define the include cntn01_swc in the class local types  under macros.
and then you create a method ....... and include the above code in that method.   excluding the include statement.
