Setting up of a new device is the easiest of all, this can be achieved by just taking the latest setup.exe or the cab files and installing them. But when there is already a SP running on the device and the device is productive, then a full or a delta patch is required to upgrade to newer SP or patches.
There are 2 SCAs which are required for the purpose of Patching. The 2 SCAs are XOCA03_0.sca and NWMCLIENT03_0.sca. Meaning of 03_0 in the name of the SCA is that this SCA is for SP03 and patch level is 0.
To move from a lower SP to a higher SP, applying the Full Patch is a must.
To send the patch to the devices via sync, the SCAs have to be loaded to DOE by transaction SDOE_UPLOAD_ARCHIVE
This SCAs contain patches for Laptop Client and PDA client namely AWT,ESWT and JSP, for each case there is a full and a delta patch. Moreover the laptop client might need WebDynpro patches which are also present in NWMCLIENT03_0.sca.
Why we need full patch and delta patch?
Within same SP to move from one patch level to another Delta patch is required. A delta patch has all the files which changed after the release of the SP except any changes to UI. Thus this is a very light way of patching.
But in case of Laptop client, to get any UI related changes Full patch needs to be applied. If there are any Webdynpro related changes, again the WebDynpro patches are required.
Similarly for PDA to get any container related changes (Ex:awt, eswt and jsp) the particular container patch is required.
Full patch is used in case of NetWeaver Mobile Laptop Client when there is any GUI related changes or changes in WebDynpro even if the upgrade is happening in the same SP. If the upgrade is between different SPs then Full patch is the only way.
While assigning the patch it is very important to check the version in the portal.
Below is the list of patches, with their descriptions, as seen in the portal after uploading the SCAs.
DELTA_PATCH_WIN32 : Delta patch for laptop
FULL_PATCH : Full patch for laptop
Mobile_Delta_Patch_ppc : Delta patch for pda runtime
Mobile_Full_Patch_Awt_ppc : Full patch for pda awt container

Mobile_Full_Patch_ppc : Full patch for pda runtime
OCA_RT_DELTAPATCH : Delta patch for pda oca container
OCA_RT_FULLPATCH : Full patch for pda oca container
WD_PATCH_1 : WebDynpro patch
WD_PATCH_2 : WebDynpro patch
When upgrading from any SPs of 7.10 or 7.11 to 7.3SPx the following patches are required.
Laptop: FULL_PATCH, WD_PATCH_1 and WD_PATCH_2.
PDA AWT: Mobile_Delta_Patch_ppc and Mobile_Full_Patch_Awt_ppc
PDA JSP: Mobile_Delta_Patch_ppc and Mobile_Full_Patch_Jsp_ppc
