It is not currently possible for schools to manually add members into Cypad; the only way for meals to be recorded is for the school to add the member into SIMS as a staff member so that they are imported into Cypad.
Although you are able to add Visitors/staff members manually in Schoolcomms, this wouldn’t pull across to Cypad.
You can however add various ‘generic’ visitor staff records in SIMS (e.g. ‘Visitor 1’, ‘Visitor 2’ etc.). These will then appear in Schoolcomms and Cypad and would allow you to record meals against them.
