A SAGE till needs a store
What you see
In the admin, when you save the till settings (a store's page in Settings › Stores, or Till close › Closing rules), a message appears with this title. Nothing is saved. The title is “A SAGE till needs a store”. Code: ZP-TILL-TILLS-INVALID.
What happened
A SAGE till has to belong to a store. Settings are saved only when they are valid, so nothing was changed and the till keeps working as before.
What to do
In Settings › Stores, every SAGE till must belong to one store. Open the store, pick its tills (or create one with New till in SAGE) and save. A till cannot be left without a store, nor shared between two.
Can zrsPOS do it for you?
No. This one needs a person.
Still stuck?
Write to support@zrspos.com and quote the code ZP-TILL-TILLS-INVALID, with the store, the till (if the store has several) and what you were doing. For the way the Till works, see the till close manual.
