Data migration Strategy - Identification of objects

Identification of Data Migration objects from each module:

It is very important that the data migration objects are identified from each module, earlier the better. All modules (SD, CS, PP, MM, FI, CO etc) leads from SAP implementation team and business team should identify all the Data migration objects from their responsible modules. It is equally important for modules leads to identify the volume of data to be migrated for the identified data migration objects.

Data type

There are four types of data involved in a SAP system: master data, Customization data, transactional data, and historical data.

• Master Data: Application master data tends to be more static once defined. Most master data can be driven by the legacy applications. Examples include vendors, customers, charts of accounts, assets, bills of materials, material masters, info records, and so on.

• Customization data: Customization data for which volume will be more and not feasible to maintain it manually, it is better to design the tools to transfer the customization data to ECC.

Example of customization data might be Release strategies, Material groups etc.

• Transactional Data. Transactional data is current and outstanding transaction data that needs to be captured from the legacy system and defined to the SAP R/3 applications for business process completion. Examples include accounting documents, open purchase orders, open sales orders, back orders, and so on.

• Historical Data. Historical data needs to be brought over from the legacy system to the SAP R/3 System for reference purposes. Examples include closed purchase orders, closed sales orders, summary general ledger information, and so on.
