Allow to extend DDMRP App to store historical data of buffers.
auto_awesome What this module does
AI-generated from the code · Odoo 19.0Stores a time-stamped history of DDMRP buffer values and shows two charts (Planning and Execution) on the buffer form, plus a report listing all buffer history records.
This module keeps a record of how each DDMRP buffer changes over time. Every time the buffer recalculation runs, a new history line is saved with the date, the buffer levels (top of red, top of yellow, top of green), the net flow position, the on-hand position and the average daily usage.
On the buffer form you get two new tabs: - Planning Chart: a stacked chart of the red, yellow and green zones over time, with lines for net flow position and on-hand position. - Execution Chart: a chart showing the execution zones and the on-hand position over time.
Both charts show a message when there is not enough data. A new report menu 'DDMRP Buffer History' under Warehouse > Reporting opens a list, pivot and graph of all history records, searchable by buffer. History lines are read-only for buffer maintainers and can only be deleted by DDMRP managers. A multi-company rule limits records to the companies the user is allowed to see. The module adds the ddmrp.history model and extends stock.buffer.
