how we Show a tree structure of all the POs that are related to the SO by the many2one “Sales Order” field in the PO in the newly created tab?
Create “Related Purchase Orders” Tab in the Sales Order to the right of “Other Information” tab in my module.
<record id="view_order_form" model="ir.ui.view">
<field name="inherit_id" ref="sale.view_order_form"/>
<field name="arch" type="xml">
<xpath expr="//page[@string='Other Information']" position="after">
<page string= "Related Purchase Orders">
In my module, In the top page of the SO form view, create two char fields, named “Project” and “Contract
NO.” Show these two fields also in the SO list view. and Create a char field in the PO form view named “Contract NO.”.
In the form view of PO, add a many2one field named “Related Sales Order”, which
contains the sale.order object. Make this field a required field, show this field also in the
list view of the PO. When choosing the “Related Sales Order” in PO, automatically pass
the “Contract NO.” from SO to PO.
last i create a new tab "Related Purchase Orders".
now i want, In the tab, show a tree structure of all the POs that are related to the SO by the
many2one “Sales Order” field in the PO.?
Please Help me
Thank you in advance.
