So, hope this is my last issue for a while. So i have one main "master" workbook that feeds information in to several other workbooks. Issues seems to be that every day we save the "master" file, then "save as" and name is the date & time, ex. Master 20210101 0600. Issue seems to be that if any of the other workbooks are open, that they will now automatically change their source from the "master" to the "Master 20210101 0600" workbook. Is there a way to edit the link so that they DO NOT change or update? Thanks.
