let xResponse := dialog(" UPDATE This Activity -> ", "Do you want to UPDATE This Activity To 'Control Deliverable' ?", ["Yes", "CANCEL"]);
if xResponse = "Yes" then
    let transId := Id;
    let updAct := 'Activities_>';
    let updRec := first(select 'Control Deliverables' where 'Activities_>' = updAct);
    let 'Activities_>' := updRec;
end

I will try to update from 'Documents' table 'Activities_>' n:1 to 'Control Deliverables' table the 'Activities_>' n:1

This is possible ??
