5 June 2010: Connector OpenERP-frePPLe: any interested souls?
OpenERP is a leading open source ERP system, which in combination with frePPLe provides a complete end-to-end solution to your planning needs.
The frePPLe team has started development of a two-way connector to OpenERP, and is eagerly looking for interested souls, contributors and guinea pigs.
Planned features:
- Two-way integration:
- Synchronizes the frePPLe database with items, locations, bill of materials, routings, resources, sales orders, customers, inventory, production orders, purchase orders from OpenERP
- Uploads new production orders and/or purchase orders from frePPLe to OpenERP
- Uses XMLRPC API to access OpenERP
- Allows to download only the objects that have been changed in OpenERP within a certain time frame. Which gives an incremental and performant execution.
- Given the many different configurations possible for OpenERP and frePPLe, a one-size-fits-all approach won't be possible. The connector will probably require customization for each use, and the code will be modular and flexible enough to allow this
5 June 2010: Beta release 0.8.1 is now available

The following enhancements are included in the new release:
- Engine:
