I am new to pega Robotics.I was trying to read from an excel file and write some new date.There are two columns in the excel. EmpName and EmpPhone columns.I have automate to read from the column.I pick each name one by one and find out the phone No from the Company CRM. I tried to write back the phone Nos to the 2nd column. Though I change the values in the proxy, the values don't get reflected in the excel.I have provided a screenshot what I am trying to do.Can you please provide some example? and want to know from where I can find some documentation for robotics components?I did the Robotics Architect Essentials course but there were lot of stuff out side that course.
