Sometimes one needs to create Workflow forecast for the case if workflow must be restarted.
Want to share a solution, I found.
First you need to have a shopping cart header guid.
DATA lo_process TYPE REF TO /sapsrm/if_wf_process. lo_process = /sapsrm/cl_wf_process_manager=>get_process_by_document( header_guid ).
So you get a worflow process instance. Then you need to reinitialize process (simulate restart)
/sapsrm/cl_wf_process_manager=>reinitialize_process( lo_process ).
This call returns true, if re-initialization was successful.
So, it’s better to pack it in IF operator
IF abap_true = /sapsrm/cl_wf_process_manager=>reinitialize_process( lo_process ). ........ ENDIF.
Now you are ready to simulate workflow
DATA ls_process_forecast TYPE /SAPSRM/S_WF_PROCESS. /sapsrm/cl_wf_apv_facade=>create_process_forecast( EXPORTING iv_document_guid = header_guid iv_document_type = /sapsrm/if_pdo_obj_types_c=>gc_pdo_shop iv_agent_id = sc_header_created_by iv_language = sc_header_language IMPORTING es_process = ls_process_forecast ).
So, in ls_process_forecast you will get a workflow simulation for the restart case.
After processing of simulation you may need to rollback the work or clear workflow simulation cache.
