Upgration of 4.6B to ECC 6.0

[Former Member]

Hi All,

if any one worked on up gradation project, please help me in this. Don't give link to SAP Market Place.

1. What are the steps/procedure to be followed in up gradation?

2. What are the precautionary measures to be taken?

3. How can we do Data Migration in case of upgradation that means down load the data(master data,open items data) from 4.6B and again upload using migration tools?

4. How can we solution manager ? Can we use any other customized tools for this? if yes what are they?

5. what is the meaning of Unicode conversion? what we have to do in this case?

6. while uploading is client has to taken separate license from SAP for ECC 6.0?

thanks & regards,

Hi Ramesh,

The first step in the upgrade is: The basis people Initially takes the copy of any SAP system(DEV, QAS or PROD) of previous one and installs the same thing in any new hardware (New SAP System). Then installs different patches and service packs related to the newer version of SAP.

Here they copy the following objects into new system.

1.Standard SAP objects.

2.Modified SAP objects.

3.Custom objects.

During the upgrade,

The standard SAP objects are overwritten by the objects in the latest release.

The modified and custom objects are adjusted.

The upgrade project mainly consists of three steps.

1.Technical upgrade: In this upgrade the functionality of the previous system has not been changed.

this is mainly about making the older system compatible with the upgraded system.

The following actions are taken in this.

1. Removing the obsolete statements and function modules.

2. Unicode conversion.

After performing this adjustments the transactions SPDD and SPAU were run to check the errors in the upgraded objects. The errors in all the objects are fixed by running this.

SPDD deals with the dictionary objects.

SPAU deals with the repository objects.

SE95 u2013Modification Browser.

SAMT u2013Extended Program Check.

After these adjustments rigorous testing has to be done to test whether the upgraded system is working as per the requirements. Unit testing, FUT( Functional unit testing), FIT (Functional Integration Testing), UAT (User Acceptance Testing) will be done in this step.

2.Functional upgrade: The new business processes introduced in the newer version are analyzed and compared with the existing processes and based on the requirements of the customer the new processes are incorporated in this upgrade.

3.Strategic Enhancements: It involves installing new and optimized business process in the latest SAP release. For example installing ESOA.(Enterprise Service Oriented Architecture). ESOA enables the user to shorten application innovation life cycle and implement strategic business enhancements at your own.

while upgrading every client should take license from SAP.Dont bother about client worries like license and all.

Hi Ramesh

regarding 1-5, I recommend you to look into the Upgrade Master Guide SAP ERP. You will find it in the box (updated versions in service.sap.com/erp-inst).

Hello Ramesh,

Migration of data is day to day activity for any system (ERP).

LSMW - Legacy System Migration Workbench

So LSMW is used for transferring (Migration) of data from one system to SAP system.

(SAP T code is u2018LSMWu2019)

The LSMW Workbench performs two main activities:-

Firstly, It reads the transfer data from one or more files (for ex.. sequential files,

Spreadsheets etc). So it transfers data from one legacy system to SAP.

This legacy system can be from different vendors like - oracle, Ramco, JDadwords..

Secondly, It Converts the data from the legacy source format to the target SAP format.

So It mainly support all kind of legacy data formats.

If any query then let me know.

Regards,

Raj

Hi Ramesh,

Data migration in upgradiation(in technical) just checking the two versions ,and mostly problem in recording of particular transaction in new version screens are changed so comparing the two screen flow do small modification .

2.in download and upload in ws_upload and ws_download are obsolute use new one like gui_upload and gui_download

These are the main points ...

Hi Ramesh

to migrate data in SAP LSMW useful.

SAP transaction code is 'LSMW'

The LSM Workbench carries out following tasks:-

1.Reads the transfer data from one or more files (for ex.. sequential files,spreadsheets etc).

2.Converts the data from the source format into the target format.

Thanks

Hi,

first of all upgrade is nothing but

Upgrade is nothing but installing a new version of software which have more functionality earlier version.

in Upgrade mainly three types

1.Technical Upgrade

2.Functional Upgrade

3.Strategic upgrade

Technical upgrade : is a fast upgrade without additional functionality but with minor user interface changes, to ensure business continuity. This upgrade type includes a cleanup of the system without implementing additional functionality, as well as technology upgrade with the opportunity to eliminate not used modifications and custom developments.

Functional upgrade : Is built on the technical upgrade, the functional upgrade provides in addition the opportunity to implement new functionalities in area like FI,HR,Logistics ..,this upgrade type also represents an opportunity to maximize the use of SAP standard functionalities by replacing custom modifications and consolidate instance or systems.

Strategic upgrade: Is driven by enterprise SOA to provide more flexibility to business process innovation. This type of upgrade approach represents a significant technology improvements step by leveraging SAP Net weaver functionality to standardize, adapt, and enable new business processes and optimized scenarios.

The major stages of a technical upgrade can be:

System preparation and stack level patch upgrade u2013 Basis Team

SPDD Phase u2013 ABAP and Functionals

Up gradation of the system u2013 Basis Team

SPAU Phase u2013 ABAP and Functionals

DBACOCKPIT for indexing u2013 ABAP TEAM

Unicode check

Unicode

u2022 In non-Unicode system, each character is represented with 8 bit code. Unicode provides a unique number for every character independent of platform, program, and language.

u2022 Unicode is a 16-bit code to represent universal character set, which is used to facilitate a better exchange of data between different systems.

u2022 E.g.: problems that may arise when communicating systems use different code pages. These problems mainly arise, because a code page is only applicable to specific languages and cannot be combined at with other code pages. Using Unicode helps you avoid these problems.

Unicode Compliance

u2022 Transaction UCCHECK

u2022 The transaction UCCHECK is used to find Unicode related issues. You can use transaction UCCHECK to examine a Unicode program set for syntax errors without having to set the program attribute "Unicode checks active" for every individual program. From the list of Unicode syntax errors, you can go directly to the affected programs and remove the errors. It is also possible to automatically create transport requests and set the Unicode program attribute for a program set.

Madhu
