Hi Wesley,
Not sure if I completely understood your questiong, but I am not aware about any possible BAPI or RFC for this process in the standard system.
I would suggest you to check for EHHSS_INC_REC_SFO_QAF_V3, with this you may be able to create the initial safety observation.
This process is better describedi in the following link:
Hope this information can help you somehow 
Best regards,
Raphael
