Project Synopsis

The Chart of Accounts Key Accounting Flex field Segment Hierarchies created in Energy General Ledger GL will be used for creating financial reports in the Data Warehouse systems for Energy Services P Ls Instance Charlie, Galaxy, etc. In order to achieve this, the GL Hierarchies will be transferred from Energy GL to P Ls Instances and thereafter Jaros will pull the GL Hierarchies details from P Ls Instances. I cover the functional design for extracting GL Hierarchies from Energy GL and loading into custom tables in P Ls Instances.

The Interface program is Design and Build to

1. Extract all GL AFF segment values and hierarchies from Energy GL

2. Load extracted data initially into staging tables and then into custom tables in P L Instance.

3. Notifications in case of errors in transmission from Energy GL to P L Instance.

Contribution:

  • As a Team Member was responsible for
  • Analysis of the BRD's provided by my IM.
  • Creation of Mappings as per the Business Logic.
  • Documentation.
  • Regularly 30 minutes interval Monitor the Trigger Table in Energy GL instance and check
  • for any new record insertion in the table columns to signal that Hierarchy Maintenance work is completed.
  • If Trigger table is updated with new record, then extract all records from Energy GL Base
  • tables as listed above and detailed in the Sections Business Rules and P L Table Design and Mapping.
  • Validate that the number of records are same in the Energy GL tables and Staging Tables of
  • P L instance.
  • In case of Loading Error, then the program should rollback and report Exception.
  • In the case of loading error in P L GL the next process of Loading to Jaros should not happen.
