Auto Approval by WF-BATCH after deadline

Hi All,

I am working on following SRM version

SRM_PLUS 702 0006 SAPK-70206INSRMPLUS SRM_PLUS for mySAP SRM

SRM_SERVER 702 0006 SAPK-70206INSRMSRV SRM_SERVER

And am using process controlled workflow.

My SC workflow has two level.

I have a requirement where for a SC for first level, after the deadline has reached i have to auto approve the SC level and SC should move to level 2.

I have written Pre exit in class /SAPSRM/CL_WF_EVENT_ADAPTER, method TRIGGER_EVENT.

To achieve this i tried many options :

1. Using FM SAP_WAPI_EXECUTE_WORKITEM, SAP_WAPI_DECISION_COMPLETE

    Result: Work item complete , workflow level still not completed

2. Use FM BBP_PD_SC_STATUS_CHANGE_WF

     Result : No impact on SC workflow

4. Use method /sapsrm/cl_wf_process_mgr_sbwf=>system_decision                                                       

     Result No impact on SC work flow

5. Used sc_adv class to set the decision

    Result : No impact on SC workflow

lo_pdo_bo_sc_adv ?= /sapsrm/cl_pdo_factory_sc_adv=>get_instance(

                iv_header_guid    = iv_document_guid

                iv_mode           = /sapsrm/if_pdo_constants_gen_c=>gc_mode_approval

                iv_user_id        = sy-uname

                iv_user_language  = sy-langu

                iv_wiid           = lv_workitem_id

              ).



              lo_pdo_bo_sc_adv->/sapsrm/if_pdo_do_approvalstat~set_item_decision( it_item_status = lt_item_approval_stat ).



              lo_pdo_bo_sc_adv->/sapsrm/if_pdo_adv_base~submit_decision(

                CHANGING

                  co_message_handler = lo_pdo_msg_consumer    " Methods for message handling

Can anyone suggest an option which i should try?
