Hello,
I was trying simple LROP Fiori Element application using RAP. I have defined single Entity with Team id & Team Name columns but in the UI (from the settings button) it was showing additional two columns called "Dyn. Method Control".
PFA screenshots for more details,
From metadata file,
<Key><PropertyRef Name="TeamId"/></Key><Property Name="Delete_mc" Type="Edm.Boolean" sap:label="Dyn. Method Control" sap:creatable="false" sap:updatable="false" sap:sortable="false" sap:filterable="false"/><Property Name="Update_mc" Type="Edm.Boolean" sap:label="Dyn. Method Control" sap:creatable="false" sap:updatable="false" sap:sortable="false" sap:filterable="false"/><Property Name="TeamId" Type="Edm.Guid" Nullable="false" sap:label="Team ID"/><Property Name="TeamName" Type="Edm.String" MaxLength="30" sap:label="Team Name" sap:creatable="false" sap:updatable="false"/>

Thanks a lot.
Best Regards,
Muthu
