EHP4 for ERP6.0 / NW2004s
Currently my system (ABAP + JAVA )is under ERP6.0 (ex: SAPKB70018 ) . Now i just want to upgrade it into EHP4.
Kindly let me know whether is it possible to directly install EHP4 on ERP6.0 or first do i need to update it to EHP1 and then to EHP4.
Thanks in advance for your support.
