Introduction

Transition Period, the period of time during which legacy system changes to new system, during that process both systems operated to sustain the business stability. In a nut shell one state or stage to another without impacting the business

Background

In order to meet the bulk upload requirement in the new SAP ECC implementation. The information to date indicates that legacy will continue to remain the custodian of master data during the transition period ann it will be replicated or synchronised with SAP ECC.

Integration Dependency

The Integration solution to fulfil the bulk upload strategy, so that

1) SAP ECC is not impacted through custom temporary interface solution.

2) Common data model can be created in SAP PI, a simple UI (User Interface) in HTML page can be created which will interact with SAP PI.

Issues for Consideration

Based on the indicative design decisions for the master and transaction upload data strategy,

1) The ability to perform bulk data maintenance of data including master and transaction data.

2) The ability to selectively choose the data attributes to maintain.

3) The ability to work offline without the need for any network connection or sessions connected to SAP ECC.

4) The capability to apply validation and authorisation controls to the individual data attributes being maintained.

5) Supports temporary legacy interface solution while the systems can evolve to interact with SAP ECC Interfaces.

                               The UI – User Interface can call the SAP standard functionality through SAP PO

                               The UI – User Interface can be developed as common data model

Stage /State Details
M,N,O & P Represented in the diagram
M – As is sate

where the file is read from the FTP/Business system direct upload

N – UI (Direct call ) where the file is read from the Business system/User directly with a UI (User Interface) tool (HTML page)
O -Evolution protocol where the data is read from the Business system directly supporting the new protocols, such as web service, JMS, JDBC, and SOAP & HTTP. The payload remains the same as current state
P – Direct upload If the user has the direct access to the SAP ECC and if the error message needs to be notified immediately to resolve it.

Protocol Comments
UI – User Interface

Custom created User Interface

With HTML page anyone can interact with SAP PI, so we can use the UI as common data model

The ability to perform bulk data maintenance of asset data including master and transaction data.

Web service

SAP PO hosts the web service call

JDBC

Through database connection parameters can connect to SAP PO directly

Queue

Any Queue mechanism can connect to SAP PO directly

File Legacy mechanism

The goal of the document is to help make users aware of the Handling bulk upload during transition period using SAP PI. Recommendations are based on my personal experience in SAP Implementation as an SAP employee and technical architect.The user can follow the suggestions provided by the document which should be supplemented with additional information. The suggestion provided by the document may vary as per the project requirement.
