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).       *-- Anupam Sharma

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. 

Tips by : Suresh Babu

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.)

What is mysap?

It's a term for all the systems that in a contract (e. g. a MySAP business suite consist of ERP2005, CRM2005, SRM2005).

What is the systems configuration required to implement SAP.. i.e for production,development and QAS servers the hard disk space, RAM, Processor

This also depends on what your are implementing, how many users will work on the system, how many records in what area are created etc.

We need a BIG database system and an even bigger application server for ~ 900 users and 12 languages.

What is ASAP?

It's an old term for an implementation strategy. Blueprint -> prototype -> goLive (if you want to say it in one sentence).

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.
