SRM - ppoma_bbp: how to link central person with the position

Hi experts,

I would need your advice. In ppoma, I see my user id contains position and a central person, ID is assigned to org structure correctly. However, in SRM my Settings, I see that the position and dept. is not visible, so I assume position is not linked to central person. Can you please advise how to link it? Should I delete the assignment at position level or CP level in ppoma and then assign the user via users_gen? Thank you very much for your soon response. Katarina
