Hi,
The support packages needs to be extracted before they are applied. Following is the command to do this.
sapcar -xvf <filename.car (in the command prompt --- if using Windows OS )
all the extracted files will be moved to the location \usr\sap\trans\EPS\in
Now, login to Sap in the 000 client with the DDIC login.
Enter tcode SPAM ---In the toolbar select Suport Packages ---> From Front end.
There is no compulsion from which package you need to start. If they are dependant, you will be displayed with a message to upgrade the dependant support pack.
It appears you are trying this for the first time, take help of someone who has expereince in it.
Regards,
Mj
