Deep Dive: Data Transfer Types and Scheduling in RSA1 [ Part 6]

In our SAP journey, we've previously discussed various types of data transfer in RSA1 and their scheduling. Today, we'll dive deeper into the pros, cons, and trade-offs of different data transfer types and elaborate further on scheduling data transfers in RSA1.




Types of Data Transfer: Pros, Cons, and Trade-offs

Full Update

Pros: A full update ensures all the data in the target system is up-to-date with the source system. It's beneficial for initial data loads or when data inconsistencies arise.

Cons: Full updates can be resource-intensive, especially for large data sets, and can affect system performance. Moreover, they can cause increased network traffic and longer system downtime.

Delta Update

Pros: Delta updates are efficient as they only transfer data that has changed since the last update, reducing the system load and network traffic.

Cons: The downside is that if a delta update fails or if there are data inconsistencies, a full update may still be required.

Direct Access

Pros: Direct access provides real-time data analysis without the need for physical data transfer. This ensures the most current data is always available for reporting.

Cons: The performance largely depends on the source system's capability to handle BW queries. Also, the source system might be stressed due to simultaneous data reads and transactional processing.

Real-Time Update

Pros: Real-time updates provide immediate data availability for reporting, which is crucial for time-sensitive business operations.

Cons: However, this might impose a significant load on both the source and BW systems due to continuous data transfers.

Scheduling Data Transfers in RSA1

Scheduling is a crucial step in the data transfer process. Let's break it down further:

  1. Select the InfoPackage: In the RSA1 interface, navigate to the Modeling tab. The InfoProvider tree displays various InfoPackages. The InfoPackage, which corresponds to the data transfer you want to schedule, needs to be selected.

  2. Schedule the InfoPackage: After selecting the InfoPackage, right-click and select 'Schedule.' It opens up the scheduling options.

  3. Set the Transfer Type: The 'Update' tab in the scheduling options allows you to choose the type of transfer (Full, Delta, Direct Access, Real-Time). The choice depends on your data transfer requirements and the capabilities of your system.

  4. Set the Schedule Options: The 'Schedule' tab provides options to start the data transfer immediately or schedule it for a later time. It also offers options to set the transfer to repeat at regular intervals, which can be daily, weekly, or custom intervals.

  5. Save and Execute the Schedule: Once you've set the options, click on 'Start' to save and execute the schedule. If you've scheduled the transfer for a later time, it will start automatically at the specified time.

Remember, scheduling should be done judiciously to optimize system performance and data availability. It's a delicate balance between meeting your data analysis requirements and ensuring your systems run smoothly.

In our upcoming blogs, we'll continue to unravel more about SAP systems and their effective utilization. Stay tuned!

How to properly Start/Stop SAP system through command line ?

Starting/stopping an SAP system is not a critical task, but the method that most of us follow to achieve this is sometimes wrong. A common mistake that most of the SAP admins do is, making use of the 'startsap' and 'stopsap' commands for starting/stopping the system.  These commands got deprecated in 2015 because the scripts were not being maintained anymore and SAP recommends not to use them as many people have faced errors while executing those scripts. For more info and the bugs in scripts, you can check the sap note 809477.  These scripts are not available in kernel version 7.73 and later. So if these are not the correct commands, then how to start/stop the sap system?  In this post, we will see how to do it in the correct way. SAP SYSTEM VS INSTANCE In SAP, an instance is a group of resources such as memory, work processes and so on, usually in support of a single application server or database server with

sapstartsrv is not started or sapcontrol is not working

 What is sapstartsrv ? The SAP start service runs on every computer where an instance of an SAP system is started. It is implemented as a service on Windows, and as a daemon on UNIX. The process is called  sapstartsrv.exe   on Windows, and   sapstartsrv   on UNIX platforms. The SAP start service provides the following functions for monitoring SAP systems, instances, and processes. Starting and stopping Monitoring the runtime state Reading logs, traces, and configuration files Technical information, such as network ports, active sessions, thread lists, etc. These services are provided on SAPControl SOAP Web Service, and used by SAP monitoring tools (SAP Management Console,  SAP NetWeaver  Administrator, etc.).

In case of linux , you can simply ps -ef | grep sapstartsrv In case of windows, you need

ST03N : The chapter for all BASIS Admins

This blog is targeted to BASIS ADMINS Transaction for workload analysis statistical data changed over time are monitored using transaction code ST03 , now ST03N (from SAP R/3 4.6C) . With SAP Web AS 6.4 the transaction ST03 is available again. From time to time ST03 and ST03N has seen many changes but later in SAP NW7.0 ST03N has reworked in detail specially processing time is now shown in separate column. Main Use of ST03N  is to get detailed information on performance of any ABAP based SAP system. Workload monitor analyzes the statistical data originally collected by kernel. You can compare or analyze the performance of a single application server or multiple application server. Using this you start checking from the entire system and finding your way to that one application server and narrowing down to exact issue. By Default :- You see data of current day as default view , you can change the default view. Source of the image : sap-perf.ca Let's discuss the WORKLOAD MONITOR By D

HANA System Replication - Prerequisites & Setup

Hey Folks! Welcome back to Hana high availability blog series. In our last blog we checked out operation & replication modes in hana system replication. If you haven't gone though that blog, you can checkout  this link In this blog we will be talking about the prerequisites of hana replication and it's setup. So let's get started. When we plan to setup hana system replication, we need to make sure that all prerequisite steps have been followed. Let's have a look at these prerequisites. HANA System Replication Prerequisites: Primary & secondary systems should be up & running HDB version of secondary should be greater than or equal to Primary database sever But, for Active/Active(read enabled config), HDB version should be same on both sites. System configuration/ini files should be identical on both sides Replication happe

HANA hdbuserstore

The hdbuserstore (hana secure user store) is a tool which comes as an executable with the SAP Hana Client package. This secure user store allows you to store SAP HANA connection information, including user passwords, securely on clients. With the help of secure store, the client applications can connect to SAP HANA without the user having to enter host name or logon credentials. You can also use the secure store to configure failover support for application servers in a 3-tier scenario (for example, SAP Business Warehouse) by storing a list of all the hosts that the application server can connect to. To access the system using secure store, there are two connect options: (1)key and (2)virtualHostName. key is the hdbuserstore key that you use to connect to SAP HANA, while virtualHostName specifies the virtual host name. This option allows you to change where the hdbuserstore searches for the data and key files. Note

How to resolve Common Error : Standard Template "sap_sm.xls" missing

Hey everyone, putting forward a common error we usually face when we have “ Excel inplace” functionality enabled in our SAP system. This error occurs when validity of the signature of SAP standard templates expired or were incorrectly delivered via support packages. We can reproduce the error by doing as below.. Click on “spreadsheet” icon after any SAP ALV grid view of data is on screen to make this data to export into excel directly from SAP.

Work Process and Memory Management in SAP

Let’s talk about the entire concepts that are related to memory when we talk about SAP Application. Starting with few basic terminologies, Local Memory :  Local process memory, the operating system keeps the two allocation steps transparent. The operating system does the other tasks, such as reserving physical memory, loading and unloading virtual memory into and out of the main memory. Shared Memory :  If several processes are to access the same memory area, the two allocation steps are not transparent. One object is created that represents the physical memory and can be used by various processes. The processes can map the object fully or partially into the address space. The way this is done varies from platform to platform. Memory mapped files, unnamed mapped files, and shared memory are used.  Extended Memory : SAP extended memory is the core of the SAP memory management system. Each SAP work process has a part reserved in its virtual address space for extended memory. You can set

ABAP Dumps Analysis

Ever now and then have you heard about ABAP Dumps, We also have a joke everything in temporary in life except ABAP dumps for SAP Consultants. Lets try to understand ABAP dumps from perspective of a SAP BASIS Consultant. Dumps happen when an ABAP program runs and something goes wrong that cannot be handled by the program We have two broad categories of Dumps , In custom program Dumps and SAP provided program Dumps. Dumps that happen in the customer namespace ranges (i.e. own-developed code) or known as Custom Program , can usually be fixed by the ABAP programmer of your team. Dumps that happen in SAP standard code probably need a fix from SAP. You do not have to be an "ABAPer" in order to resolve ABAP dump issues. The common way to deal with them is to look up in ST22 How to correct the error ? Hints are given for the keywords that may be used to search on the note system. Gather Information about the issue  Go to System > Status and Check the Basis SP level as well as info

SAP system migration blog series - part 1: migration overview

Summary : This blog is part 1 of the blog series on SAP system migration. In this blog, we will provide overview about SAP migration, types of migration, their differences and usage scenario. SAP migration overview :   As the Greek philosopher, Heraclitus, said: “change is the only constant.” Same goes within SAP world too, often customer have to change the SAP systems along with its underlying components to meet the changing requirements, be it change from old hardware to new one, changing operating system, database. This change in SAP system components (DB, OS or Hardware) is termed as migration. Before we go into details of migration, let’s understand architecture of a typical SAP system.   An SAP system consist of SAP application instances, running on database (DB), hosted on operating system (OS), provisioned on hardware. Change in any one or more of these underlying components (DB, OS or hardware) warrant us to perform migration. Types of migration:   Broadly, there are two types
