Let’s say there are two workbooks with the same name and same data in prod. One is owned by Alex and another is by Carl. What I did is I downloaded the workbook from Carl made changes and published it. But it has to be for Alex only. There is a small difference which is one of the worksheet only a display changes not entire data or column. Now the actual need is to make changes to the Alex one and publish it. My question is since i published the Carl one yesterday the owner changed from Carl to my name and if I publish the Alex one today after the changes . Will two workbooks be there or only one? Because after publishing the owner will be my name. Please someone answer on this
