Client operates in multiple geographies - North Central and South America, Europe; Africa, Russia & Caspian; Middle East & North Africa; and Asia Pacific.

Project Scope

Client implemented Oracle ERP Cloud and engaged ChainSys as its data migration partner utilizing the ChainSys dataZap offering. As part of the Oracle Cloud deployment, Client needed data migration from legacy systems for more than thirty five objects that were primarily loaded to the following tracks - Procurement, Inventory & Payable Systems. The key challenge was around multiple source systems and transformation requirements to assure data readiness for loading to the Oracle Cloud target system. This was easily accomplished through dataZap, which offered automation capability for extraction and transformation.

Business Situation

Client’s legacy systems offered exceptional challenges since the data had to be cleansed as well as transformed prior to migration to Oracle Cloud ERP. Also, getting a view of the data transformation requirements was the key to success, which was enabled by putting functional teams in-place that had knowledge in both the legacy and Oracle target application.



Technical Situation

ChainSys deployed dataZap to help with the data migration. Data was directly extracted from multiple legacy systems via templates configured specifically for each system. The data transformations were incorporated into dataZap, which assured that source data was correctly mapped to the target Oracle Cloud application. dataZap was used for automated loading into the Oracle Cloud via FBDI / Web services. Data cleansing was carried out by ChainSys’s dataZen.

Solutions

ChainSys deployed its dataZap product for migrating data from Legacy systems to Oracle Cloud ERP. The master data was cleansed prior to the migration using the ChainSys dataZen.

  • Business data from 17 Countries and 74 Legal entities
  • Data cleansing and Governance - Item and Supplier data
  • Data Migration - Item and Supplier master data, Purchase Requisitions and Purchase Orders transaction data and Open and Historical transactions for all Open Projects.
  • Template based data conversion and load  for each Oracle cloud data object 
  • Automated data extraction process from legacy application,  automated transformation rules using global cross reference value sets
  • Custom pre-validation and post validation business rules

Benefits

  • Ability to implement multiple iterations of data conversions in quick succession utilizing pre-configured templates
  • Improved data quality and on-going quality assurance, easing business operations
  • Improved process accuracy and efficiency with clean data.
  • Regional roll-outs were easy and faster with the Global implementation of master data.
  • Reusability of the dataZap & dataZen multiple times on phased rollouts.

The key to success was the ability to transform the data per client’s needs and the reusability of templates that accelerated the data migration and assured process accuracy.
