Supplier Calendar

Beta License: LGPL-3 OCA/purchase-workflow Translate me on Weblate Try me on Runbot

This module adds a Calendar to the ResPartner model. This calendar can then used as the basis of the proper computation of start/end dates based on the delivery lead time of the supplier in this and other modules.

In this module, the calendar is considered in the computation of the schedules date of a stock picking and in the order date of a purchase order.

Table of contents


  • Go to Settings and activate the developer mode.
  • Go to Settings > Technical > Resource > Working Time and define your resource calendar.
  • Go to Contacts > Sales&Purchases > Purchase > Delay Calendar Type and assign Supplier Calendar and in Factory Closing Days assign the Resource Calendar desired.


When a picking is created from a purchase order of a supplier, the lead time used to calculate the scheduled date is computed in natural days. At the same time, when a purchase order is created due to a a procurement evaluation, its order date is also computed considering the lead time in natural days. THis module adds the possibility of expressing the lead time of a vendor in his own calendar. This way, the order dates of purchase orders and the scheduled dates of receipts will only take into account the supplier working days.
