Hi everybody,

Hopefully someone is able to help me 🙂 !

I need help to patch a sharepoint list, when an external user hits on a button. I can't see a problem here.

The external user has been added to the sharepoint list for access as a guest user.

After the external user hits the button "Termin buchen" , nothing happens. The sharepoint list doesn't fill the entries from the user.

Button "Termin buchen" - On Select:

Patch(
Rolloutdaten;
LookUp(
Rolloutdaten;
ID = varselectedApt.ID
);
{
Kommentar: Kommentarbox_1.Text;
Status: "gebucht";
Rollouttyp: "HO";
Teilnehmer: Emailbox_HO.Text;
Abteilung: Abteilungbox_HO.Text;
Telefonnummer: Telbox_HO.Text;
PCName: Pcnamebox_HO.Text;
Straße_Nr: Straßebox_HO.Text;
PLZ: PLZbox_HO.Text;
Ort: Ortbox_HO;
Vorname: Vornamebox_HO.Text;
Nachname: Nachnamebox_HO.Text
}
);;

Navigate(Termin_buchen_screen)

Can anybody help? That would be great.
Greetings!

Monika

Hi @monikakokot,

Do you want the external users to update the SP list in Power Apps?

As I know, PowerApps has already supported to share an app with guests. However, guests may only be assigned the Edit permission, and not the Co-owner role, for apps shared with them. This means that the shared app is read-only for the guests, edit or create is not allowed for guests.

In a word, if you want the external users to update SharePoint record in PowerApps, you should make sure that you ahve assigned the full access or Edit permission of the SharePoint list to the external users.

Hi Qi,

Thanks a lot for your answer. I changed the permission of the guestuser to edit - I will try it again.

Regards,
Monika
