Restart flow

Question

Hello All,
Could you help me!
I try to call FM SAP_WAPI_ADM_WORKFLOW_RESTART  twice in one session for one ID.
First time FM return error. In this session i fix all errors. But second time FM return Error too.
In new session FM doen't return error.
      LOOP AT lt_rows INTO ls_rows.
        READ TABLE <ft_data> ASSIGNING <fs_data> INDEX ls_rows-index.
        IF sy-subrc EQ 0.
          ASSIGN COMPONENT 'WI_ID' OF STRUCTURE <fs_data> TO <fs_id>.
          CALL FUNCTION 'SAP_WAPI_ADM_WORKFLOW_RESTART'
            EXPORTING
              workitem_id   = <fs_id>    
              do_commit     = 'X'
            TABLES
              message_lines = lt_return.
        ENDIF.
      ENDLOOP.
How can i make error does not occur in same session?

Hi Artem
I don't know what excaltly is causing the error and how and where are you trying to fix the same. (You should have used SWIA instead ).
But, remember that SAP WAPIs too are function modules and would load the entire Function Group memory in the first call to any FM from that group. It is quite possible that internally, the Functions are reading buffered values and hence giving you an error. In a new session, the FG memory is reloaded and buffered values are reset .... hence it's not giving the error.
Can you elaborate on why are you doing the above, what is the need and why in a loop ....what WI IDs are in <ft_data>? and why SWIA is not preferred?

PS: the first line in the API used by you is
lh_wapi = cl_swf_utl_wapi_framework=>create( im_language = language )
If you check this method, it creates the framework only if it does not exists, else it passes what is available.
