There are multiple LPARs with different CPU serials on the same CPU machine.
Does an Already Exists error occur when uploading ISV-SCRT reports created in these LPARs to the SCRT portal site?
The SCRT portal site also checks the CPU serial information when uploading.
Therefore, even if the CPU model and type are the same, if the CPU serial information is different, an Already Exist Error will not occur and you can upload the data.
