differences between implementation and support

Hi ,

What is the differnce between implementation/Roll out/upgrade and support projects?

Which will be easier for an ABAPer to work it on?

Plz go through this u understand the types of projects and differences.

Difference between implementation, support & upgradation projects and the role of ABAPer in each of them

SAP Implementation:

SAP Implementation is the whole of processes that defines a complete method to

implement SAP software in an organization. It is based on best practices and case studies from various literature sources and presents a collection of processes and products that make up a complete implementation method to allow any organization to plan and execute the implementation of SAP (ERP) software. The SAP implementation process is made up out of four main phases, i.e. the project preparation where a vision of the future-state of the SAP solution is being created, a sizing and blueprinting phase where the solution stack is created and training is being performed, a functional development phase and finally a final preparation phase, when the last tests are being performed before the actual go live.

ABAP Developer Role is to prepare the Technical Specification (based on a Functional Specification given by a Functional Consultant), build the code, Review the code and finally to prepare the Unit Test Cases. Sometimes ABAPer may be asked to do a technical research for an optimal solution.

SAP Support:

After a go live, the application needs a maintenance/support to resolve the issues/tickets raised by the users when using the application. Ticket is like a request for changes/bug fixing or a request for a new ABAP Developer Role includes bug fixing/change the existing code due to new requirements/build a new code etc.

SAP Upgrade:

SAP Upgrade is nothing but upgrading the software with a superior version which has got more advantages when compared to the earlier version.

ABAP Developer Role is to go through transactions SPAU/SPDD to compare the old and new version of the change and finally need to activate the relevant one. Some times might need to work on SAP notes too.

hi,

Implementation

Customer wants to install SAP/Include different modules of SAP viz. MM/SD/FI/CO/PP etc. This is implementation project. Here one needs to integrate several modules, migrate data from Legacy system to SAP system. Need to prepare interfaces/RFC’s to interact with 3rd party systems.

Support

Customer has already installed SAP & wants to give the work of maintaining those systems. This is support project

Upgrade

Customer has SAP Version 4.6b and wants to update his version i.e. wants to go to Version 4.7. This is upgrade project

Rollouts

Customer has upgraded his version & wants to rollout country specific changes.

This is rollout project

Role of abaper is comaparitivly easier on roll out and upgrade projects.

Hope this is helpful, Do reward.

Basically support projects are 'easier' as you will mostly do only minor changes to existing programs.

But sometimes this is what makes it hard, as you will have to mess around with somebody elses code.

In general you can´t really say what is easier, as it depends on the project scope.
