What is th difference between Sap lock and database lock?

A "SAP lock" is named "enqueue lock", the enqueue is on a much higher level, e. g. a complete sales document is locked there whereas in the datbase usually only row locks exist. Since SAP runs on more database than Oracle (thanx god) one needed to have a mechanism, that is database independent and on a higher level.

I would like to know is there anyway to transport roles from Production to Development or Sandbox.

Goto PFCG and enter the role which you want to transfer to other system. goto utilities->Mass download it will ask the path where to download/save that role on local desktop give the location and save it. Next logon to the system where you want that particular role.

PFCG-> Role -> upload.

Give the path where the role is saved. it accepts and generates successfully.

To develop and custamize SAP to companies requirement. say if you dont have DEV, after go-live(started using SAP (PRD}) if you want to do some changes to application, you cannot do changes directly to PRD server, which may cause problem the PRD server live data. so you do the required changes on DEV first and test them on QAS, if it works fine then transport the same to PRD.

What is the correct use of SPAM, SAINT, SPAD and SPDD transactions. When should we use each?

SPAM is for installing support packages, SAINT is used to install new addons. SPAD is for creating printers (I assume you meant SPAU) and SPDD is for adjusting modification to dictionary objects.


Is it possible to update Support Release packages from OS level?


No - you can import them but the full process will require additional steps the tools "tp" and "R3trans" are not aware of. The way is to use SPAM - but SPAM has the possibility to schedule those imports in the background.


After doing any Support Package update in SPAM, are there any further steps to carry out for this update to take effect?


No, they are active immediately.

SAP Administration Questions Answers

What is the use of profile paramater ztta/roll_area?

The value specifies the size of the roll area in bytes. The roll area is one of several memory areas, which satisfies the user requests of user programs. For technical reasons, however, the first 250 KB or so of a user context are always stored in the roll area, further data

- up to the roll area limit ztta/roll_first,

- in the extended memory, up to the limit ztta/roll_extension or if extended memory is exhausted, then

- again in the roll area, until the roll area is full, then

- in the local process area, up to the limit abap/heap_area_dia or abap/heap_area_total or until the address space or the swap space is exhausted.

Followed by termination with errors like STORAGE_PARAMETERS_WRONG_SET an error code, that points to memory bottleneck Minimum data transfer with context change; however, the increase helps to avoid problems (address space, swap space, operating system paging).


What is R/3? and what is basis version?

SAP Basis:

- Provides the runtime environment for all SAP applications

- Optimally embeds the application in the system environment

- Defines a stable architecture framework for system enhancements

- Contains the tools for administering the entire system

- Allows the distribution of resources and system components

- Provides interfaces for decentralized system parts and external products.

An R/3 instance is a group of R/3 services that are started and stopped as a unit (by an R/3 dispatcher) and have a common instance profile. The name of an R/3 instance is composed of letters standing for the relevant services, and an instance number which is unique for each computer. The services may be D, V, E, B, M, G, or S, which respectively stand for dialogue, update, enqueue, background, message, gateway, and spool services.


I would like to know the version or name of SAP that is implemented in real time?

This is a very generic question and really depends on what you are implementing (modules).

The history of the "R/3" is

3.0D Basis 300

3.0E Basis 300

3.0F Basis 300

3.1H Basis 310

3.1I Basis 310

4.0B Basis 400

4.5B Basis 450

4.6C Basis 460

4.71 Basis 6.20

4.72 Basis 6.20

5.00 Basis 6.40 (ECC 5.0 - Enterprise Core components)

6.00 Basis 7.00 (ECC 6.0) - actually in RampUp

All of those have increased business functionality and interfaces to other systems (CRM, BW etc.)

How should I set priority for Printing say like user, teamlead, project manager?

There's nothing like "priority" settings for spool processes. Just define more (profile parameter rdisp/wp_no_spool) processes so people don't need to wait.

Using Tc SGEN I have generated 74% job and later I have terminated the job. I wish to start generating from where it stopped I have refreshed but to no chance nothing was done. How should I further proceed so as to complete the remaining job..

Start SGEN again and select the same you have selected before. It will popup and ask if you want to start from scratch or generate the just the remaining.
