Openbravo connector

FrePPLe provides an integration with Openbravo, a leading open source agile ERP system.

Overview

The connector provides the following functionality:

Two-way integration:
- Synchronizes the frePPLe database with items, locations, bill of materials, routings, resources, sales orders, customers, inventory, production orders, purchase orders from Openbravo.
- Uploads new production requirements, purchase requisitions and expected delivery date of sales orders from frePPLe to Openbravo.
Uses the standard web services API to access Openbravo. No changes are required on Openbravo side.
For optimal performance the connector allows net-change download. Only the objects that have been created or changed in Openbravo within a certain time frame are extracted.
You can still maintain additional data in the frePPLe user interface. I.e. Openbravo doesn’t need to be the only source of data for your frePPLe model.
Easy to customize.

The connector uses the standard Openbravo web services (see http://wiki.openbravo.com/wiki/XML_REST_Web_Services ) to read and write data.

Coded in Python, the connector can easily be updated to match the customizations done in your Openbravo deployment.
The connector has been validated with Openbravo 16Q3.3.

For integration of work requirements the Advanced Warehousing Operations (see http://wiki.openbravo.com/wiki/Modules:Advanced_Warehouse_Operations ) is recommended, as it provides an additional web service that provides a better workflow for the end users.

Importing data from Openbravo into frePPLe

You can run the import interface in 2 ways:

Interactively from the frePPLe user interface.

The execute screen has a specific section where you can launch the import connector.

You can specify the number of days of recent changes you want to extract from Openbravo.
From the command line script.

The script is especially handy when you want to run the interface automatically, e.g. with a cron job.

Issue one of the commands below. The second command runs an incremental import of the Openbravo objects that have been changed in the last 7 days.
```
frepplectl openbravo_import
frepplectl openbravo_import --delta=7
```

Exporting data from frePPLe to Openbravo

You can bring the planning results to Openbravo in three ways:

Incremental export from the frePPLe user interface

User can select proposed purchase orders, distribution orders or manufacturing orders in the frePPLe screens, and then use the action menu to bring them immediately to Openbravo.
Bulk export from the frePPLe user interface.

The execute screen has a specific section where you can launch the export connector. This allows to export all proposed transactions meeting certain criteria to Openbravo.

Three parameters define a filter criterion to select which transactions will be included in the bulk exports.
Bulk export from the command line.

Issue the command below. The script is especially handy when you want to run the interface automatically.
```
frepplectl openbravo_export
```

It is possible to combine both the incremental and bulk export in the same frePPLe instance. For instance, proposed purchase orders for a total value less than a certain dollar threshold can be exported automatically to Openbravo. Proposed purchase orders above the threshold are then reviewed in frePPLe by the planner, and export incrementally upon the planners’ approval.

Technical configuration

Edit the configuration file djangosettings.py

The file is found under /etc/frepple (linux) or <install folder>bincustom (Windows).

Assure that the freppledb.openbravo is included in the setting INSTALLED_APPS which defines the enabled extensions. By default it is not enabled.
Migrate your frePPLe database

Run the migrate command to add some extra fields in the database, and load the connector parameters.
```
frepplectl migrate
```
Configure the following parameters

In the frePPLe user interface, the menu item ‘admin/parameters’ opens a data table to edit these.
- openbravo.host: host where the Openbravo web service is running
- openbravo.user: Openbravo user used to for the connection
- openbravo.password: Password for the connection
  
  For improved security it is recommended to specify this password in the setting OPENBRAVO_PASSWORDS in the djangosettings.py file rather then using this parameter.
- openbravo.date_format: Date format for openbravo webservice filter
  
  Date format defaults to %Y-%m-%d (i.e. YYYY-MM-DD) but can here be changed to other formats like %m-%d-%Y (i.e. MM-DD-YYYY).
- openbravo.exportPurchasingPlan
  
  By default we export purchase requisitions and manufacturing work orders.
  
  By switching this flag to true, we will export to the purchaseplan object instead, which is where the Openbravo MRP run normally stores its results. Switch this flag to true only if you have specific customizations using the purchaseplan table.
- openbravo.filter_export_purchase_order
  
  Filter expression purchase orders for bulk export of purchase orders.
- openbravo.filter_export_manufacturing_orderfilter:
  
  Filter expression for bulk export of manufacturing orders.
- openbravo.filter_export_distribution_order
  
  Filter expression for bulk export of distribution orders.

Data mapping details

The connector doesn’t cover all possible configurations of Openbravo and frePPLe. The connector is quite likely to require some customization to fit the particular setup of the Openbravo and the planning requirements in frePPLe.
