   The tp buffer contains old, not completely processed OCS Packages
   Interrupt the import due to an error situation (21.09.2011, 10:08:12)
   Display detailed informations concerning the error in phase 'CHECK_REQUIREMENTS'
   Abort the import due to an error situation (21.09.2011, 10:08:19)

Solution:
If you execute
tp showbuffer <sid> pf=<path to transport profile> tag=SPAM
You can either delete these from the buffer if they are old packages that have been imported previously or if the buffer does not contain transports that you need, you could simply reset the current spam queue so it is empty.

Then rename the actual buffer file to OLD_<buffer file name> and create a new buffer in usr/sap/trans/buffer

Go to /usr/sap/trans/buffer
 take backup of buffer (e.g <SID> DEV)
# touch DEV
