Why to I get the following error when I enter the DMP command to delete a data set entry?
SCNO0-08 INVALID INPUT REQUEST
The DMP command look for entries to dump from the SASDS and the UNC command look for entries in the IDS.
The reason you get the "SCNO0-08 INVALID INPUT REQUEST" message is because no entry was found n the SASDS
