I have a requirement that automatically backup the date set while your editing it. for example, you locate a PDS member named CWS1001.DM.PLI(MSNABC). If you edited it correctly, there is nothing to do, otherwise we need to recover that data set manually. of course, we need to backup the source data set before do any changes. this is normal process.
I need to confirm with you all that Is available to automatic backup data set. If so. con you give me detailed process to achieve it.
yes, It's easy to recover by using command UNDO. But the method you mentioned is to UNDO before save the records.
my requirement is to automatically backup the data sets before you edit records. Of cause we can use command COPY to achieved.
