Create line items and event content

Hi Ariba experts,

I have a doubt whe creating a sourcing Project. I´m the Project owner of the Project but I would like to add a partner job in a team member  created by me so he can help me doing the soucing Project.

Well the doubt is simple, I can´t find any permissions to allow my team member to introduce event content, line ítems, etc..

Would you help me??

Thanks in advance!

Ana
