how to check & fix probles while apply kjp in solaris10?

# ./installpatchset --s10patchset
....
PaTcH_MsG 23 Patch number 146681-02 cannot be applied until all         restricted patches are backed out
solution:
Please Note : we have to Backout IDR Patch No IDR148092-01 before proceeding to KJP. IDR patch was interim patch  provided to us which is causing error now.
I have backed out  IDR Patch No IDR148092-01    for  p60app01 (10.66.230.50). You can proceed further for KJP installation.


# patchrm IDR148092-01
it removes successfuly


 # pwd

/tmp/10_Recommended


 # cd patches


 # patchadd 146681-02
now it add successfully
