Sorry @rohitsbots for the long delay in responding 🙂 . I really appreciate your return.
I referred to SOA because of a process we already have in the company, where it generates an xml (3.6mb) with the data I need.
Today I upload the xml with automate through xpath to the sharepoint list!
But I wanted a way for SOA itself to feed the list, without having to use the xml generated by it.
