Automating Subscription Contract Conversion to Oracle Fusion
When customers move from legacy platforms to Oracle Fusion, one of the biggest data conversion challenges is Subscription Contracts. Oracle provides Import Management as the standard tool for loading this data. While it works, it also brings a lot of complexity.
Subscription Contracts are hierarchical — Headers, Products, Covered Levels, Bill Levels. Import Management expects separate CSV templates for each of those layers. They must be prepared, loaded, and error-resolved one at a time.
The challenges in the Import Management Approach
Traditional Import Management based uploads come with a few recurring pain-points:
- Multi-template dependency
Creation of multiple templates, mapping rules, and linking keys across levels is difficult and error prone. - Partial or broken contracts
If one level fails (e.g. Covered Levels) while Headers + Products already loaded, the system ends up with incomplete contracts that must be cleaned, retried or manually repaired. - High volume becomes unmanageable
When you are dealing with hundreds of thousands of contracts — the challenges with incomplete contracts multiply quickly.
The Automation Approach
In a recent Oracle Fusion implementation, the ask was to bring Subscription Contracts from Oracle EBS to Fusion Cloud. The dataset was large – about 350,000 contracts – as we were bringing both active and recently expired contracts for business continuity.
Loading these via Import Management would have taken significant manual effort, multiple iterations, and would have caused incomplete contracts issues.
To simplify the conversion, Apps Associates built a fully automated mechanism in which we treated each subscription contract as a single logical entity.
Instead of converting individually at Header, Products, Covered and Bill Lines etc., we devised an automated code to:
- Export contracts as a unified structure
- Run a Python script to build JSON payloads
- Invoke Fusion Subscription REST API to load contract as a single entity
Automation Flow
- Extract Data from Source Systems
A single SQL procedure was written which read Subscriptions data from different tables and consolidated into a single csv file. This csv file combined all subscription levels of headers, product lines, covered lines and bill levels into a single row. - Run Python Script
The Input parameter to the script is the csv file. Once the csv is read the script performs the following
- Validate Contract Data for data accuracy
- Prepare and invoke Fusion Rest API to create contracts
- Handle & Log API Response
Conclusion
Using this automation, we were able to convert and load 350K+ contracts over a period of 2 days with no partial records and efficient error reporting.
If you’re dealing with similar legacy migrations, especially from Oracle EBS, we can help build an automated loader which can significantly reduce both risk and effort over iterations.
