HI Drew,
Thank you for responding, let me be precise here below:
1) Installed the gateway and established the connection to SharePoint On-Prem
2) I have given the URL for the Site and able to get the SharePoint List reference under Data Verse -> Table
3) In the SharePoint On-Prem list I have a choice field called Status with Values (Initiated, Pending, Approved)
4) In Power Apps under Table when I opened the referenced table I do not see the Status field
5) Due to which I cannot add that field in the Power Page.
Hope I am clear now.
