出现这种错误的时候可能是由以下几种原因造成的：
1. Tablespaces may be full or may not have much space.

2. Another possible solution for a case when the client copy failed could be wth the RFC destinations in SM59.
Try out this method:
Add an RFC destination that looks like this:
Name: FINBTR@<SID>CLNT< xxx>
Type: 3
Desc: RFC Destination for System <SID> Client <xxx>
Target Host: <host name>
System Number: <system number>
Client: xxx
User: <RFC user>
Password: <RFC User password>
