Some of the Important SAP Notes that I recently used to setup an End-to-End SAP Sybase Mobile CRM landscape (SMP links - Secure Access required)
Following are some of the SAP Notes that I went through in one of the recent landscape build for deploying SAP Sybase CRM Mobile Sales application. Please note that this is not complete list of material (reference guides, notes, etc.) that you would have to go over in order for a successful implementation. It's just a reference and a hint of what would the effort include and look like.
For a setup from scratch, it would involve installing an SAP CRM 7.0 system, meeting all the pre-requisites of Mobile Gateway and upgrading to desired SP level (or latest available SP level), applying SAP Notes, installation of an SAP NW Mobile DOE system with again meeting all pre-requisites of DOE connector and applying SAP Notes, SPs, etc., installation and configuration of an SUP server from SAP Sybase, installation and configuration of an SAP Sybase Relay Server, Installing SAP Sybase Mobile Client application, configuring mobile devices such as iPhones, iPads, iPods (with Touch functionality), and trigger/test the initial loading.
How would you setup Environment Variable 'ORACLE_HOME'?
For each SAP Application Server in the landscape, users <SAPSID>adm on
Windows and ora<DBSID> on Unix are needed to setup a User Specific
environment variable 'ORACLE_HOME'.
Windows and ora<DBSID> on Unix are needed to setup a User Specific
environment variable 'ORACLE_HOME'.

list of SAP system users, such as:

TP - Transport Control Program in SAP
Some important information on TP:
1) If a change request (a transport request) has an object with an
error or would generate an error, and if another transport request
with an object that would repair the previous object with an eror,
then the ultimate outcome will not have any errors in the runtime
environment of target system, if both the requests are moved/imported
together in a queue.
2) Before the MAIN import phase starts, tp imports and activates ABAP
Dictionary Structures. This way the structures are current and able to
receive new data.
3) In case of multiple transport requests in a queue, tp processes
each import step for all requests in a queue before moving on with the
next step in Import procedure.

Sequence of applying SAP Support Packs
Focusing on sequence of applying SAP Support Packs, how would you apply them? Take current SP level is 03, and the downloaded SAP SP packs are 04, 05, 06, 07, and 08?
You MUST follow the numbered order when applying the Support Packs because of pre-requisite dependencies. In the above case, you MUST apply them starting 04, then 05, 06, 07, and last 08. You CANNOT apply SAP Support Packs with jumping directly to say 07, then come back for 04.
You may want to remember the word: ARBITRARY - this means you decide with a random choice. Which SHOULD NOT be the case when applying the SAP Support Packs.
So, if there is an interview question, if SAP SP can be applied ARBITRARILY, i.e. randomly, then the answer is NO, it cannot.
Parameters to set Initial and Maximum J2EE Heap size
The typical parameter would look like:
-Xms=256m
-Xmx=512m
Here, note that the difference is 's' and 'x'.
's' is used to set Initial J2EE Heap size
'x' is used to set Maximum J2EE Heap size
Transport Paths
Name a few transport paths you have used in your transport landscape:
1) Delivery Path
2) Consolidation Path
How would you generate RFC destinations for Transport Management System (TMS) connections?
When you initialize TMS setup, they're generated automatically. These RFC destinations are between the Domain Controller and all memeber SAP systems in the Transport Domain.

Standard Clients and Users delivered with an SAP system
With a new SAP system, more than one clients are delivered in-built. They are 000,066, and 001. Total possible number of clients in a given SAP system would be 1,000. That is 000 to 999 (means 999 + 1 (this one is for client 000) = 1,000)
Along with the default clients there are some users come created with the system. They are SAP*, DDIC, and EARLYWATCH.
The above is important to know and note because you would need a user immediately after installing the system. This information is usually available in the installation guides but it's always good to remember and keep the fundamental know-how crystal clear.
