@Julia van orsouw, unfortunately I can't reply to your comment due to low karma. Yes, you are correct about the Analytic Account, we are able to use that field and collect financial data.

However, it's the workflow or nature of our organization, (I haven't yet came across anyone is like us from odoo topic s online). We need to create an order while it's in CRM stage, then it will be linked to a project.

Therefore, the order will be linked to both CRM and Project. We've created a customized section in both CRM and Project to show all Orders linked to them.

However, this only works when we can select/edit project_id field, which we were able to do in Sale.Order.form because there was a hidden field created by odoo initially, which we were able to utilize.

But, we can't do the same for Purchase.order form. We can make customized field for analytic account itself, but any purchases edited manually will not be able to associate with the CRM and Project even when we have assigned them to the right analytic account. As we monitor projects more than using it as an organizer, it's really like the central control hub for everything, freight, delivery, installation, field survey, quote, p.o, invoice and etc.

All we need to do is to be able to add customized field in Quote, Sales Order, and Purchase, which we were able to do for all of them by utilizing what's already (hidden) there, except for Purchase.

I understand now that project_id (name) field is an inherit field, maybe that's why we weren't able to do anything about it.

I'm wondering if there's anyway of inherit project_id in purchase module without using python code via pycharm.

Thank you or anyone reading this
