With Odoo's advanced searching and filtering features, you might be able to update the contacts in bulk so that they are linked to the business.

Hi,

You can do it by utilizing the mass editing feature in odoo list view, by default the company field is readonly in the tree view, so if you are using studio, you can remove the readonly attribute from the field, and if you don't have access to studio,

1.  enable developer mode

2. click on debugger button after opening the contacts tree view

3. click edit view: list

4. set readonly="0" for company_id field

5. refresh the view, select all the contacts, click on company field and enter the value

6. Once it is saved, bring back the readonly to 1

Thanks

Hi,

Select the contacts that you want to modify in tree view. Export them from action -> export. Export the file as xlsx or csv which ever is convenient (don’t forget to export the company_id field). Then edit the file and give the value for company_id as required (id of the company you want). Then import the file from Favorite -> Import records. Click on Upload File button and choose the file and open. After choosing the necessary fields, click on Import button.
