Hello everyone,


I would like to do something like this: location = Production

  • 1. within the selected range of time 'start_date' and 'end_date'

  • 2. count product in location for every week, then average the weekly quantity,

  • 3. count total of the product in location for a each month within this range of time and average the monthly quantity

  • 4. based on this information calculate minimum of the product in stock 'MWoS',

  • 5. check if product level is lower than '150% of MWoS' if so send message or give a notification about the product ;)


    I know, I can do something like this directly in Odoo but the whole process is far too complicated so I decided to create an addon which will do this thing in one click .... ok, not in one ... in four :)
    But still it's quicker than digging, setting everything up for each product etc.
    So far I can check quantities in location, count it within selected range of time then check details if needed.

    In a code there is a definition which count days, weeks (don't need days :)) need months, but how to use it to check and count product for every week and record it, then check for a month and record it ?
    I hope you know what I mean .......
